- } -``` - -我们想对它做增强，那么可以编写下面的代码： - -```java - public String hello(String str) { - System.out.println("before"); - Object value = InstrumentApi.invokeOrigin(); - System.out.println("after, result: " + value); - return object; - } -``` - -增强后的结果是： - -```java - public String hello(String str) { - System.out.println("before"); - Object value = "hello " + str; - System.out.println("after, result: " + value); - return object; - } -``` - -**这种方式可以随意插入代码，非常灵活。** - -## 示例 - -以`ByteKitDemo.java`为例说明，[[查看源文件](src/test/java/com/example/ByteKitDemo.java)]。 - -### 1. 定义注入点和Binding数据 - -* 在下面的 SampleInterceptor 时定义了要注入 `@AtEnter`/`@AtExit`/`@AtExceptionExit`三个地方， -* 用`@Binding`绑定了不同的数据 -* 在`@AtEnter`里配置了 `inline = true`，则说明插入的`SampleInterceptor#atEnter`函数本身会被inline掉 -* 配置了 `suppress = RuntimeException.class` 和 `suppressHandler = PrintExceptionSuppressHandler.class`，说明插入的代码会被 `try/catch` 包围 - -```java - public static class SampleInterceptor { - - @AtEnter(inline = true, suppress = RuntimeException.class, suppressHandler = PrintExceptionSuppressHandler.class) - public static void atEnter(@Binding.This Object object, - @Binding.Class Object clazz, - @Binding.Args Object[] args, - @Binding.MethodName String methodName, - @Binding.MethodDesc String methodDesc) { - System.out.println("atEnter, args[0]: " + args[0]); - } - - @AtExit(inline = true) - public static void atExit(@Binding.Return Object returnObject) { - System.out.println("atExit, returnObject: " + returnObject); - } - - @AtExceptionExit(inline = true, onException = RuntimeException.class) - public static void atExceptionExit(@Binding.Throwable RuntimeException ex, - @Binding.Field(name = "exceptionCount") int exceptionCount) { - System.out.println("atExceptionExit, ex: " + ex.getMessage() + ", field exceptionCount: " + exceptionCount); - } - } -``` - -### 2. @ExceptionHandler - -在上面的 `@AtEnter`配置里，生成的代码会被 try/catch 包围，那么具体的内容是在`PrintExceptionSuppressHandler`里 - -```java - public static class PrintExceptionSuppressHandler { - - @ExceptionHandler(inline = true) - public static void onSuppress(@Binding.Throwable Throwable e, @Binding.Class Object clazz) { - System.out.println("exception handler: " + clazz); - e.printStackTrace(); - } - } -``` - -### 3. 查看反编译结果 - -原始的Sample类是： - -```java - public static class Sample { - private int exceptionCount = 0; - - public String hello(String str, boolean exception) { - if (exception) { - exceptionCount++; - throw new RuntimeException("test exception, str: " + str); - } - return "hello " + str; - } - } -``` - -增强后的字节码，再反编译： - -```java -package com.example; - -public static class ByteKitDemo.Sample { - private int exceptionCount = 0; - - public String hello(String string, boolean bl) { - try { - String string2 = "(Ljava/lang/String;Z)Ljava/lang/String;"; - String string3 = "hello"; - Object[] arrobject = new Object[]{string, new Boolean(bl)};

 ##### Can arthas view the value of a variable in memory?
 
 No. But you can use some tricks to intercept the object with the `tt` command, or fetch it from a static method.
+
+
+#### How to filter method with the same name?
+
+You can used all variables in [fundamental fields in expressions](advice-class.md) for the condition express to filter method with the same name, you can use the number of parameters `params.length ==1`,parameter type `params[0] instanceof java.lang.Integer`,return value type `returnObj instanceof java.util.List` and so on in one or more combinations as condition express.
+
+You can use `-v` to view the condition express result [https://github.com/alibaba/arthas/issues/1348](https://github.com/alibaba/arthas/issues/1348)
+
+example [arthas-demo](quick-start.md)
+
+```bash
+watch demo.MathGame primeFactors traceE '{params,returnObj,throwExp}' -v -n 5 -x 3 'params.length >0 && returnObj instanceof java.util.List'

+不能。但可以用一些技巧，用`tt`命令拦截到对象，或者从静态函数里取到对象。
+
+
+##### 方法同名过滤
+
+同名方法过滤可以通过匹配表达式,可以使用[表达式核心变量](advice-class.md)中所有变量作为已知条件,可以通过判断参数个数`params.length ==1`, 参数类型`params[0] instanceof java.lang.Integer`、返回值类型 `returnObj instanceof java.util.List` 等等一种或者多种组合进行过滤。
+
+可以使用 `-v` 查看观察匹配表达式的执行结果 [https://github.com/alibaba/arthas/issues/1348](https://github.com/alibaba/arthas/issues/1348)

+> Load the external `*.class` files to retransform the loaded classes in JVM.
+
+Reference: [Instrumentation#retransformClasses](https://docs.oracle.com/javase/8/docs/api/java/lang/instrument/Instrumentation.html#retransformClasses-java.lang.Class...-)
+
+### Usage
+
+```bash
+   retransform /tmp/Test.class
+   retransform -l
+   retransform -d 1                    # delete retransform entry
+   retransform --deleteAll             # delete all retransform entries
+   retransform --classPattern demo.*   # triger retransform classes
+   retransform -c 327a647b /tmp/Test.class /tmp/Test\$Inner.class
+   retransform --classLoaderClass 'sun.misc.Launcher$AppClassLoader' /tmp/Test.class
+```
+
+### retransform the specified .class file 
+
+```bash
+$ retransform /tmp/MathGame.class
+retransform success, size: 1, classes:
+demo.MathGame
+```
+
+Load the specified .class file, then parse out the class name, and then retransform the corresponding class loaded in the jvm. Every time a `.class` file is loaded, a retransform entry is recorded.
+
+> If retransform is executed multiple times to load the same class file, there will be multiple retransform entries.
+
+### View retransform entry
+
+```bash
+$ retransform -l
+Id ClassName LoaderHash LoaderClassName
+1 demo.MathGame null null
+```
+
+### Delete the specified retransform entry
+
+Need to specify id:
+
+```bash
+retransform -d 1
+```
+
+### Delete all retransform entries
+
+```bash
+retransform --deleteAll
+```
+
+### Explicitly trigger retransform
+
+```bash
+$ retransform --classPattern demo.MathGame
+retransform success, size: 1, classes:
+demo.MathGame
+```
+
+> Note: For the same class, when there are multiple retransform entries, if retransform is explicitly triggered, the entry added last will take effect (the one with the largest id).
+
+### Eliminate the influence of retransform
+
+If you want to eliminate the impact after performing retransform on a class, you need to:
+
+* Delete the retransform entry corresponding to this class
+* Re-trigger retransform
+
+> If you do not clear all retransform entries and trigger retransform again, the retransformed classes will still take effect when arthas stop.
+
+### Use with the jad/mc command
+
+```bash
+jad --source-only com.example.demo.arthas.user.UserController > /tmp/UserController.java
+
+mc /tmp/UserController.java -d /tmp
+
+retransform /tmp/com/example/demo/arthas/user/UserController.class
+```
+
+* Use `jad` command to decompile bytecode, and then you can use other editors, such as vim to modify the source code.
+* `mc` command to compile the modified code
+* Load new bytecode with `retransform` command
+
+### Tips for uploading .class files to the server
+
+The `mc` command may fail. You can modify the code locally, compile it, and upload it to the server. Some servers do not allow direct uploading files, you can use the `base64` command to bypass.
+
+1. Convert the `.class` file to base64 first, then save it as result.txt
+
+    ```bash
+    Base64 < Test.class > result.txt
+    ```
+
+2. Login the server, create and edit `result.txt`, copy the local content, paste and save
+
+3. Restore `result.txt` on the server to `.class`
+
+    ```
+    Base64 -d < result.txt > Test.class
+    ```
+
+4. Use the md5 command to verify that the `.class` files are consistent.
+
+
+### Restrictions of the retransform command
+
+* New field/method is not allowed
+* The function that is running, no exit can not take effect, such as the new `System.out.println` added below, only the `run()` function will take effect.
+
+    ```java
+    public class MathGame {
+        public static void main(String[] args) throws InterruptedException {
+            MathGame game = new MathGame();
+            while (true) {
+                game.run();
+                TimeUnit.SECONDS.sleep(1);
+                // This doesn't work because the code keeps running in while
+                System.out.println("in loop");
+            }
+        }
+
+        public void run() throws InterruptedException {
+            // This works because the run() function ends completely every time
+            System.out.println("call run()");
+            try {
+                int number = random.nextInt();
+                List primeFactors = primeFactors(number);
+                print(number, primeFactors);
+
+            } catch (Exception e) {
+                System.out.println(String.format("illegalArgumentCount:%3d, ", illegalArgumentCount) + e.getMessage());

+retransform

+> 加载外部的`.class`文件，retransform jvm已加载的类。
+
+参考：[Instrumentation#retransformClasses](https://docs.oracle.com/javase/8/docs/api/java/lang/instrument/Instrumentation.html#retransformClasses-java.lang.Class...-)
+
+
+### 使用参考
+
+```bash
+   retransform /tmp/Test.class
+   retransform -l
+   retransform -d 1                    # delete retransform entry
+   retransform --deleteAll             # delete all retransform entries
+   retransform --classPattern demo.*   # triger retransform classes
+   retransform -c 327a647b /tmp/Test.class /tmp/Test\$Inner.class
+   retransform --classLoaderClass 'sun.misc.Launcher$AppClassLoader' /tmp/Test.class
+```
+
+### retransform 指定的 .class 文件
+
+```bash
+$ retransform /tmp/MathGame.class
+retransform success, size: 1, classes:
+demo.MathGame
+```
+
+加载指定的 .class 文件，然后解析出class name，再retransform jvm中已加载的对应的类。每加载一个 `.class` 文件，则会记录一个 retransform entry.
+
+> 如果多次执行 retransform 加载同一个 class 文件，则会有多条 retransform entry.
+
+### 查看 retransform entry
+
+```bash
+$ retransform -l
+Id                  ClassName           LoaderHash          LoaderClassName
+1                   demo.MathGame       null                null
+```
+
+### 删除指定 retransform entry
+
+需要指定 id：
+
+```bash
+retransform -d 1
+```
+
+### 删除所有 retransform entry
+
+```bash
+retransform --deleteAll
+```
+
+### 显式触发 retransform
+
+```bash
+$ retransform --classPattern demo.MathGame
+retransform success, size: 1, classes:
+demo.MathGame
+```
+
+> 注意：对于同一个类，当存在多个 retransform entry时，如果显式触发 retransform ，则最后添加的entry生效(id最大的)。
+
+### 消除 retransform 的影响
+
+如果对某个类执行 retransform 之后，想消除影响，则需要：
+
+* 删除这个类对应的 retransform entry
+* 重新触发 retransform
+
+> 如果不清除掉所有的 retransform entry，并重新触发 retransform ，则arthas stop时，retransform过的类仍然生效。
+
+
+### 结合 jad/mc 命令使用
+
+```bash
+jad --source-only com.example.demo.arthas.user.UserController > /tmp/UserController.java
+
+mc /tmp/UserController.java -d /tmp
+
+retransform /tmp/com/example/demo/arthas/user/UserController.class
+```
+
+* jad命令反编译，然后可以用其它编译器，比如vim来修改源码
+* mc命令来内存编译修改过的代码
+* 用retransform命令加载新的字节码
+
+### 上传 .class 文件到服务器的技巧
+
+使用`mc`命令来编译`jad`的反编译的代码有可能失败。可以在本地修改代码，编译好后再上传到服务器上。有的服务器不允许直接上传文件，可以使用`base64`命令来绕过。
+
+1. 在本地先转换`.class`文件为base64，再保存为result.txt
+
+    ```bash
+    base64 < Test.class > result.txt
+    ```
+
+2. 到服务器上，新建并编辑`result.txt`，复制本地的内容，粘贴再保存
+
+3. 把服务器上的 `result.txt`还原为`.class`
+
+    ```
+    base64 -d < result.txt > Test.class
+    ```
+
+4. 用md5命令计算哈希值，校验是否一致
+
+### retransform的限制
+
+* 不允许新增加field/method
+* 正在跑的函数，没有退出不能生效，比如下面新增加的`System.out.println`，只有`run()`函数里的会生效
+
+    ```java
+    public class MathGame {
+        public static void main(String[] args) throws InterruptedException {
+            MathGame game = new MathGame();
+            while (true) {
+                game.run();
+                TimeUnit.SECONDS.sleep(1);
+                // 这个不生效，因为代码一直跑在 while里
+                System.out.println("in loop");
+            }
+        }
+
+        public void run() throws InterruptedException {
+            // 这个生效，因为run()函数每次都可以完整结束
+            System.out.println("call run()");
+            try {
+                int number = random.nextInt();
+                List primeFactors = primeFactors(number);
+                print(number, primeFactors);
+
+            } catch (Exception e) {
+                System.out.println(String.format("illegalArgumentCount:%3d, ", illegalArgumentCount) + e.getMessage());
+            }
+        }
+```

+{"timestamp":1550223186170,"status":500,"error":"Internal Server Error","exception":"java.lang.IllegalArgumentException","message":"id < 1","path":"/user/0"}
+```
+
+下面通过热更新代码，修改这个逻辑。
+
+### jad反编译UserController
+
+`jad --source-only com.example.demo.arthas.user.UserController > /tmp/UserController.java`{{execute T2}}
+
+jad反编译的结果保存在 `/tmp/UserController.java`文件里了。
+
+再打开一个`Terminal 3`，然后用vim来编辑`/tmp/UserController.java`：
+
+`vim /tmp/UserController.java`{{execute T3}}
+
+比如当 user id 小于1时，也正常返回，不抛出异常：
+
+```java
+    @GetMapping(value={"/user/{id}"})
+    public User findUserById(@PathVariable Integer id) {
+        logger.info("id: {}", (Object)id);
+        if (id != null && id < 1) {
+			return new User(id, "name" + id);
+            // throw new IllegalArgumentException("id < 1");
+        }
+        return new User(id.intValue(), "name" + id);
+    }
+```
+
+### sc查找加载UserController的ClassLoader
+
+`sc -d *UserController | grep classLoaderHash`{{execute T2}}
+
+```bash
+$ sc -d *UserController | grep classLoaderHash
+ classLoaderHash   1be6f5c3
+```
+
+可以发现是 spring boot `LaunchedURLClassLoader@1be6f5c3` 加载的。
+
+注意hashcode是变化的，需要先查看当前的ClassLoader信息，提取对应ClassLoader的hashcode。
+
+如果你使用`-c`，你需要手动输入hashcode：`-c `
+
+对于只有唯一实例的ClassLoader可以通过`--classLoaderClass`指定class name，使用起来更加方便.
+
+`--classLoaderClass` 的值是ClassLoader的类名，只有匹配到唯一的ClassLoader实例时才能工作，目的是方便输入通用命令，而`-c `是动态变化的。
+
+### mc
+
+保存好`/tmp/UserController.java`之后，使用`mc`(Memory Compiler)命令来编译，并且通过`--classLoaderClass`参数指定ClassLoader：
+
+`mc --classLoaderClass org.springframework.boot.loader.LaunchedURLClassLoader /tmp/UserController.java -d /tmp`{{execute T2}}
+
+```bash
+$ mc --classLoaderClass org.springframework.boot.loader.LaunchedURLClassLoader /tmp/UserController.java -d /tmp
+Memory compiler output:
+/tmp/com/example/demo/arthas/user/UserController.class
+Affect(row-cnt:1) cost in 346 ms
+```
+
+也可以通过`mc -c  /tmp/UserController.java -d /tmp`，使用`-c`参数指定ClassLoaderHash:
+
+```bash
+$ mc -c 1be6f5c3 /tmp/UserController.java -d /tmp
+```
+
+### retransform
+
+再使用`retransform`命令重新加载新编译好的`UserController.class`：
+
+`retransform /tmp/com/example/demo/arthas/user/UserController.class`{{execute T2}}
+
+```
+$ retransform /tmp/com/example/demo/arthas/user/UserController.class
+retransform success, size: 1
+```
+
+### 热修改代码结果
+
+`retransform`成功之后，再次访问 https://[[HOST_SUBDOMAIN]]-80-[[KATACODA_HOST]].environments.katacoda.com/user/0 ，结果是：
+
+```
+{
+  "id": 0,
+  "name": "name0"
+}
+```

+This case introduces the ability to dynamically update code via the `jad`/`mc`/`retransform` command.
+
+Currently, visiting http://localhost/user/0 will return a 500 error:
+
+`curl http://localhost/user/0`{{execute T3}}
+
+```
+{"timestamp":1550223186170,"status":500,"error":"Internal Server Error","exception":"java.lang.IllegalArgumentException","message":"id < 1","path":"/user/0"}
+```
+
+This logic will be modified by `retransform` command below.
+
+## Use jad command to decompile UserController
+
+`jad --source-only com.example.demo.arthas.user.UserController > /tmp/UserController.java`{{execute T2}}
+
+The result of jad command will be saved in the `/tmp/UserController.java` file.
+
+
+Then open `Terminal 3`, use `vim` to edit `/tmp/UserController.java`:
+
+`vim /tmp/UserController.java`{{execute T3}}
+
+For example, when the user id is less than 1, it also returns normally without throwing an exception:
+
+```java
+    @GetMapping(value={"/user/{id}"})
+    public User findUserById(@PathVariable Integer id) {
+        logger.info("id: {}", (Object)id);
+        if (id != null && id < 1) {
+			return new User(id, "name" + id);
+            // throw new IllegalArgumentException("id < 1");
+        }
+        return new User(id.intValue(), "name" + id);
+    }
+```
+
+### Use sc command to find the ClassLoader that loads the UserController
+
+`sc -d *UserController | grep classLoaderHash`{{execute T2}}
+
+```bash
+$ sc -d *UserController | grep classLoaderHash
+ classLoaderHash   1be6f5c3
+```
+
+It can be found that it is loaded by spring boot `LaunchedURLClassLoader@1be6f5c3`.
+
+Note that the hashcode changes, you need to check the current ClassLoader information first, and extract the hashcode corresponding to the ClassLoader.
+
+if you use`-c`, you have to manually type hashcode by `-c `.
+
+For classloader with only one instance, it can be specified by `--classLoaderClass` using class name, which is more convenient to use.
+
+The value of `--classloaderclass` is the class name of classloader. It can only work when it matches a unique classloader instance. The purpose is to facilitate the input of general commands. However, `-c ` is dynamic.
+
+### mc
+
+After saving `/tmp/UserController.java`, compile with the `mc` (Memory Compiler) command and specify the ClassLoader with the `--classLoaderClass` option:
+
+`mc --classLoaderClass org.springframework.boot.loader.LaunchedURLClassLoader /tmp/UserController.java -d /tmp`{{execute T2}}
+
+```bash
+$ mc --classLoaderClass org.springframework.boot.loader.LaunchedURLClassLoader /tmp/UserController.java -d /tmp
+Memory compiler output:
+/tmp/com/example/demo/arthas/user/UserController.class
+Affect(row-cnt:1) cost in 346 ms
+```
+
+You can also execute `mc -c  /tmp/UserController.java -d /tmp`，using `-c` to specify ClassLoaderHash:
+
+```bash
+$ mc -c 1be6f5c3 /tmp/UserController.java -d /tmp
+```
+
+### retransform
+
+Then reload the newly compiled `UserController.class` with the `retransform` command:
+
+`retransform /tmp/com/example/demo/arthas/user/UserController.class`{{execute T2}}
+
+```
+$ retransform /tmp/com/example/demo/arthas/user/UserController.class
+retransform success, size: 1
+```
+
+### Check the results of the hotswap code
+
+After the `retransform` command is executed successfully, visit https://[[HOST_SUBDOMAIN]]-80-[[KATACODA_HOST]].environments.katacoda.com/user/0 again.
+
+The result is:
+
+```
+{
+  "id": 0,

+![Arthas](https://arthas.aliyun.com/doc/_images/arthas.png)
+
+`Arthas` is a Java diagnostic tool open-sourced by Alibaba middleware team. Arthas helps developers in trouble-shooting issues in production environment for Java based applications without modifying code or restarting servers.
+
+`Arthas` supports JDK 6+, supports Linux/Mac/Windows.
+
+## Background
+
+Oftentimes the production system network is inaccessible from local development environment. If issues are encountered in production systems, it is impossible to use IDE to debug the application remotely. What’s even worse, debugging in production environment is unacceptable, as it will suspend all the threads, leading to services downtime.
+
+Developers could always try to reproduce the same issue on the test/staging environment. However, this is tricky as some issues cannot be reproduced easily in a different environment, or even disappear once restarted.
+
+And if you’re thinking of adding some logs to your code to help trouble-shoot the issue, you will have to go through the following lifecycle: test, staging, and then to production. Time is money! This approach is inefficient! Worse still, the issue may not be fixed since it might be irreproducible once the JVM is restarted, as described above.
+
+Arthas is built to solve these issues. A developer can troubleshoot production issues on the fly. No JVM restart, no additional code changes. Arthas works as an observer, that is, it will never suspend your running threads.
+
+## Key features
+
+- Check whether a class is loaded? Or where the class is loaded from? (Useful for trouble-shooting jar file conflicts)
+- Decompile a class to ensure the code is running as expected.
+- Check classloader statistics, e.g. the number of classloaders, the number of classes loaded per classloader, the classloader hierarchy, possible classloader leaks, etc.
+- Check the method invocation details, e.g. method parameter, returned values, exceptions and etc.
+- Check the stack trace of specified method invocation. This is useful when a developer wants to know the caller of the method.
+- Trace the method invocation to find slow sub-invocations.
+- Monitor method invocation statistics, e.g. QPS (Query Per Second), RT (Return Time), success rate and etc.
+- Monitor system metrics, thread states and CPU usage, GC statistics and etc.
+- Supports command line interactive mode, with auto-complete feature enabled.
+- Supports telnet and WebSocket, which enables both local and remote diagnostics with command line and browsers.
+- Supports profiler/Flame Graph
+- Supports JDK 6+
+- Supports Linux/Mac/Windows
+
+This tutorial takes a normal Spring Boot application as an example to demonstrate the the usage of mc-retransform.

+retransform success, size: 1, classes:
+com.example.demo.arthas.user.UserController
+```
+
+> Note: For the same class, when there are multiple retransform entries, if retransform is explicitly triggered, the entry added last will take effect (the one with the largest id).
+
+### Eliminate the influence of retransform
+
+If you want to eliminate the impact after performing retransform on a class, you need to:
+
+* Delete the retransform entry corresponding to this class
+* Re-trigger retransform
+
+> If you do not clear all retransform entries and trigger retransform again, the retransformed classes will still take effect when arthas stop.
+
+
+After deleting the retransform entry above and explicitly triggering the retransform, you can use the `jad` command to confirm that the result of the previous retransform has been eliminated.

+Dynamic trace by specifying `listenerId`, you can go deeper and deeper. In addition, commands such as `watch`/`tt`/`monitor` also support similar functionality.
+
+
+### Trace result time inaccuracy problem
+
+For example, in the following result: `0.705196 > (0.152743 + 0.145825)`
+
+```bash
+$ trace demo.MathGame run -n 1

+
+So where is the rest of the time consumed?
+
+1. Methods that are not traced to. For example, methods under `java.*` are ignored by default. This can be printed out by adding the `-skipJDKMethod false` parameter.
+

 通过指定`listenerId`的方式动态trace，可以不断深入。另外 `watch`/`tt`/`monitor`等命令也支持类似的功能。
+
+
+### trace结果时间不准确问题
+
+比如下面的结果里：`0.705196 > (0.152743 +  0.145825)`
+
+```bash
+$ trace demo.MathGame run -n 1
+Press Q or Ctrl+C to abort.

+        `---[0.145825ms] demo.MathGame:print() #25
+```
+
+那么其它的时间消耗在哪些地方？
+
+1. 没有被trace到的函数。比如`java.*` 下的函数调用默认会忽略掉。通过增加`--skipJDKMethod false`参数可以打印出来。
+
+    ```bash
+    $ trace demo.MathGame run --skipJDKMethod false
+    Press Q or Ctrl+C to abort.
+    Affect(class count: 1 , method count: 1) cost in 35 ms, listenerId: 2

+    ```
+2. 非函数调用的指令消耗。比如 `i++`, `getfield`等指令。
+
+3. 在代码执行过程中，JVM可能出现停顿，比如GC，进入同步块等。

 ### Best practices
 
+> Note that the agentId must be unique, otherwise it will conflict on the tunnel server and not work properly.
+
 If the arthas agent is configured with `appName`, the generated agentId will be prefixed with `appName`.
 
 For example, if you add the startup parameter `as.sh --tunnel-server 'ws://127.0.0.1:7777/ws' --app-name demoapp`, the generated agentId might be `demoapp_URJZ5L48RPBR2ALI5K4V`.

 ### 最佳实践
 
+> 注意，agentId要保持唯一，否则会在tunnel server上冲突，不能正常工作。
+
 如果 arthas agent配置了 `appName`，则生成的agentId会带上`appName`的前缀。
 
 比如在加上启动参数：`as.sh --tunnel-server 'ws://127.0.0.1:7777/ws' --app-name demoapp` ，则生成的agentId可能是`demoapp_URJZ5L48RPBR2ALI5K4V`。

+Demonstrate the workflow of the `ognl` expression in the `watch` command in Arthas. You can modify the expressions in `Demo.java`, and compile and run the code.
+
+Project: https://github.com/hengyunabc/ognl-demo
+
+# Open the Demo.java file
+
+`src/main/java/com/example/ognl/Demo.java`{{open}}
+
+# Compile and run the code
+
+`mvn compile exec:java`{{execute}}
+
+Expression in the code:
+
+```java
+String watchExpress = "{target, params, returnObj, #cost}";
+String conditionExpress = "params[0] > 1 && #cost > 0.1";
+```
+
+The result is similar to the following expression:
+
+```bash
+watch com.example.ognl.TestService test "{target, params, returnObj, #cost}" "params[0] > 1 && #cost > 0.1" -x 3
+```
+
+# View the expression result when the method throws an exception

+Expression in the code:
+
+```java
+String watchExpress = "{target, params, throwExp}";
+String conditionExpress = "params[0] > 1";

+
+```bash
+watch com.example.ognl.TestService test "{target, params, throwExp}" "params[0] > 1" -e -x 2

+##step1 在您的pom.xml中增加profile配置
+```

+        
+        
+            windows
+        
+    
+
+```
+##step2 在您的pom.xml中引入依赖
+PS：一定要配置好profile，不然无法自动生成``配置。
+```
+
+    com.taobao.arthas
+    mana-pool-analyzer
+    ${arthas.vision}
+    ${os_family}-${os.arch}
+
+```
+
+##step3 如果没有合适的版本
+1. 如果是32位的操作系统，不好意思，目前暂不支持。
+
+2. 如果是64位操作系统，请先尝试`mvn clean compile package install -DskipTests=true -U`把依赖安装到本地；
+
+3. 如果报错，请先确保您本地的g++编译器能够正常工作，再重新尝试`mvn clean compile package install -DskipTests=true -U`；
+

+ * AWT native interface (new in JDK 1.3)
+ *
+ * The AWT native interface allows a native C or C++ application a means
+ * by which to access native structures in AWT.  This is to facilitate moving
+ * legacy C and C++ applications to Java and to target the needs of the
+ * community who, at present, wish to do their own native rendering to canvases
+ * for performance reasons.  Standard extensions such as Java3D also require a
+ * means to access the underlying native data structures of AWT.
+ *
+ * There may be future extensions to this API depending on demand.
+ *
+ * A VM does not have to implement this API in order to pass the JCK.
+ * It is recommended, however, that this API is implemented on VMs that support
+ * standard extensions, such as Java3D.
+ *
+ * Since this is a native API, any program which uses it cannot be considered
+ * 100% pure java.

+ * AWT Native Drawing Surface (JAWT_DrawingSurface).
+ *
+ * For each platform, there is a native drawing surface structure.  This
+ * platform-specific structure can be found in jawt_md.h.  It is recommended
+ * that additional platforms follow the same model.  It is also recommended
+ * that VMs on Win32 and Solaris support the existing structures in jawt_md.h.
+ *
+ *******************
+ * EXAMPLE OF USAGE:
+ *******************
+ *
+ * In Win32, a programmer wishes to access the HWND of a canvas to perform
+ * native rendering into it.  The programmer has declared the paint() method
+ * for their canvas subclass to be native:
+ *
+ *
+ * MyCanvas.java:
+ *
+ * import java.awt.*;
+ *
+ * public class MyCanvas extends Canvas {
+ *
+ *     static {
+ *         System.loadLibrary("mylib");
+ *     }
+ *
+ *     public native void paint(Graphics g);
+ * }
+ *
+ *
+ * myfile.c:
+ *
+ * #include "jawt_md.h"
+ * #include 
+ *
+ * JNIEXPORT void JNICALL
+ * Java_MyCanvas_paint(JNIEnv* env, jobject canvas, jobject graphics)
+ * {
+ *     JAWT awt;
+ *     JAWT_DrawingSurface* ds;
+ *     JAWT_DrawingSurfaceInfo* dsi;
+ *     JAWT_Win32DrawingSurfaceInfo* dsi_win;
+ *     jboolean result;
+ *     jint lock;
+ *
+ *     // Get the AWT
+ *     awt.version = JAWT_VERSION_1_3;
+ *     result = JAWT_GetAWT(env, &awt);
+ *     assert(result != JNI_FALSE);

-1. 如果是32位的操作系统，不好意思，目前暂不支持。
-
-2. 如果是64位操作系统，请先尝试`mvn clean compile package install -DskipTests=true -U`把依赖安装到本地；

+
+`vmtool` uses the `JVMTI` to support `getInstances` in jvm and `forceGc`.
+
+* [JVM Tool Interface](https://docs.oracle.com/javase/8/docs/platform/jvmti/jvmti.html)
+
+### getInstances
+
+```bash
+vmtool --action getInstances --className java.lang.String --limit 10
+```
+
+> Through the `--limit` parameter, you can limit the number of return values to avoid pressure on the JVM when obtaining large data. The default value of limit is 10.
+
+### Specify classloader name
+
+```bash
+vmtool --action getInstances --classLoaderClass org.springframework.boot.loader.LaunchedURLClassLoader --className org.springframework.context.ApplicationContext
+```
+
+
+### Specify classloader hash
+
+The classloader that loads the class can be found through the `sc` command.
+
+```bash
+$ sc -d org.springframework.context.ApplicationContext
+ class-info org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext
+ code-source file:/private/tmp/demo-arthas-spring-boot.jar!/BOOT-INF/lib/spring-boot-1.5.13.RELEASE.jar!/
+ name org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext
+...
+ class-loader +-org.springframework.boot.loader.LaunchedURLClassLoader@19469ea2
+                     +-sun.misc.Launcher$AppClassLoader@75b84c92
+                       +-sun.misc.Launcher$ExtClassLoader@4f023edb
+ classLoaderHash 19469ea2
+```
+
+Then use the `-c`/`--classloader` parameter to specify:
+
+```bash
+vmtool --action getInstances -c 19469ea2 --className org.springframework.context.ApplicationContext
+```
+
+### Specify the number of expanded layers of returned results
+
+> The return result of the `getInstances` action is bound to the `instances` variable, which is an array.
+
+> The expansion level of the result can be specified by the `-x`/`--expand` parameter, the default value is 1.
+
+```bash
+vmtool --action getInstances -c 19469ea2 --className org.springframework.context.ApplicationContext -x 2
+```
+
+### Execute expression
+
+> The return result of the `getInstances` action is bound to the `instances` variable, which is an array. The specified expression can be executed through the `--express` parameter.
+
+```bash
+vmtool --action getInstances --classLoaderClass org.springframework.boot.loader.LaunchedURLClassLoader --className org.springframework.context.ApplicationContext --express'instances[0].getBeanDefinitionNames()'
+```
+
+### Force GC
+
+```bash
+vmtool --action forceGc
+```

+[`vmtool`在线教程](https://arthas.aliyun.com/doc/arthas-tutorials.html?language=cn&id=command-vmtool)
+
+`vmtool` 利用`JVMTI`接口，实现查询内存对象，强制GC等功能。
+
+* [JVM Tool Interface](https://docs.oracle.com/javase/8/docs/platform/jvmti/jvmti.html)
+
+### 获取对象
+
+```bash
+vmtool --action getInstances --className java.lang.String --limit 10
+```
+
+> 通过 `--limit`参数，可以限制返回值数量，避免获取超大数据时对JVM造成压力。默认值是10。
+
+### 指定 classloader name
+
+```bash
+vmtool --action getInstances --classLoaderClass org.springframework.boot.loader.LaunchedURLClassLoader --className org.springframework.context.ApplicationContext
+```
+
+
+### 指定 classloader hash
+
+可以通过`sc`命令查找到加载class的 classloader。
+
+```bash
+$ sc -d org.springframework.context.ApplicationContext
+ class-info        org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext
+ code-source       file:/private/tmp/demo-arthas-spring-boot.jar!/BOOT-INF/lib/spring-boot-1.5.13.RELEASE.jar!/
+ name              org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext
+...
+ class-loader      +-org.springframework.boot.loader.LaunchedURLClassLoader@19469ea2
+                     +-sun.misc.Launcher$AppClassLoader@75b84c92
+                       +-sun.misc.Launcher$ExtClassLoader@4f023edb
+ classLoaderHash   19469ea2
+```
+
+然后用`-c`/`--classloader` 参数指定：
+
+```bash
+vmtool --action getInstances -c 19469ea2 --className org.springframework.context.ApplicationContext
+```
+
+### 指定返回结果展开层数
+
+> `getInstances` action返回结果绑定到`instances`变量上，它是数组。
+
+> 通过 `-x`/`--expand` 参数可以指定结果的展开层次，默认值是1。
+
+```bash 
+vmtool --action getInstances -c 19469ea2 --className org.springframework.context.ApplicationContext -x 2
+```
+
+### 执行表达式
+
+> `getInstances` action返回结果绑定到`instances`变量上，它是数组。可以通过`--express`参数执行指定的表达式。
+
+```bash
+vmtool --action getInstances --classLoaderClass org.springframework.boot.loader.LaunchedURLClassLoader --className org.springframework.context.ApplicationContext --express 'instances[0].getBeanDefinitionNames()'
+```
+
+### 强制GC
+
+```bash
+vmtool --action forceGc
+```
