### 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
|
||
|
|
```
