# Nacos Config 2.4.x Example
|
||||
|
||||
## 项目说明
|
||||
|
||||
Spring Boot 2.4.0 版本开始默认不启动 bootstrap 容器
|
||||
本项目演示如何在 Spring boot >= 2.4.0 版本不启用 bootstrap 容器情况下如何使用 nacos
|
||||
|
||||
[Nacos](https://github.com/alibaba/Nacos) 是阿里巴巴开源的一个更易于构建云原生应用的动态服务发现、配置管理和服务管理平台。
|
||||
|
||||
## 示例
|
||||
|
||||
### 如何接入
|
||||
|
||||
1. 首先，修改 pom.xml 文件，引入 Nacos Config Starter
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>org.springframework.boot</groupId>
|
||||
<artifactId>spring-boot-starter-web</artifactId>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>com.alibaba.cloud</groupId>
|
||||
<artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
|
||||
<!-- 不再需要 bootstrap 容器 -->
|
||||
<exclusions>
|
||||
<exclusion>
|
||||
<groupId>org.springframework.cloud</groupId>
|
||||
<artifactId>spring-cloud-starter-bootstrap</artifactId>
|
||||
</exclusion>
|
||||
</exclusions>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
|
||||
2. 在应用的 /src/main/resources/***application.yml*** 配置文件中配置 Nacos Config 元数据
|
||||
```yaml
|
||||
server:
|
||||
port: 8888
|
||||
spring:
|
||||
application:
|
||||
name: nacos-config-import-example
|
||||
cloud:
|
||||
nacos:
|
||||
config:
|
||||
name: test.yml
|
||||
file-extension: yml
|
||||
# 2.4.0 新增配置 spring.config.import
|
||||
config:
|
||||
import:
|
||||
- optional:nacos:localhost:8848
|
||||
```
|
||||
|
||||
3. 在 nacos 创建 test.yml
|
||||
```yaml
|
||||
configdata:
|
||||
user:
|
||||
age: 21
|
||||
name: freeman
|
||||
map:
|
||||
hobbies:
|
||||
- art
|
||||
- programming
|
||||
intro: Hello, I'm freeman
|
||||
users:
|
||||
- name: dad
|
||||
age: 20
|
||||
- name: mom
|
||||
age: 18
|
||||
```
|
||||
|
||||
4. 完成上述操作后，应用会从 Nacos Config 中获取相应的配置，并添加在 Spring Environment 的 PropertySources 中
|
||||
```java
|
||||
// controller
|
||||
@RestController
|
||||
public class UserController {
|
||||
|
||||
@Autowired
|
||||
private UserConfig userConfig;
|
||||
|
||||
@GetMapping
|
||||
public String get() throws JsonProcessingException {
|
||||
return new ObjectMapper().writeValueAsString(userConfig);
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
// ConfigurationProperties
|
||||
@ConfigurationProperties(prefix = "configdata.user")
|
||||
public class UserConfig {
|
||||
private String name;
|
||||
private Integer age;
|
||||
private Map<String, Object> map;
|
||||
private List<User> users;
|
||||
// getters and setters ...
|
||||
|
||||
public static class User {
|
||||
private String name;
|
||||
private Integer age;
|
||||
// getters and setters ...
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
验证动态刷新
|
||||
访问 http://localhost:8888
|
||||
再从 nacos 修改配置, 再次访问即可验证动态配置生效
