spring-cloud-config 配置管理

spring-cloud-config client 服务端

Maven 导入

<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-actuator</artifactId>
</dependency>

1.Application 类上增加 @EnableConfigServer

2.application.properties 配置

server.port = 9090
spring.application.name = ws
### 拉取远程git中配置
spring.cloud.config.server.git.uri = file:///G:/project/git-test
### 关闭actuator验证
management.endpoint.beans.enabled = false

3.增加 git 文件

ws.properties 内容:my.name = default

ws-dev.properties 内容:my.name = dev

4.测试

http://localhost:9090/ws-default.properties 会出现 my.name: test123,表示成功!

spring-cloud-config client 客户端

Maven 导入

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-config</artifactId>
</dependency>

1.增加 bootstrap.properties

# 配置服务器url
spring.cloud.config.uri = http://localhost:9090/
# 远程地址properties 前缀 [ws.properties]
spring.cloud.config.name = ws
# 远程地址properties -后缀 [ws-dev.properties]
spring.cloud.config.profile = default
# git仓局分支
spring.cloud.config.label = master

2.修改 application.properties

spring.application.name = client
#springcloud-Finchley.SR1版本中,意思是:使用包含暴露的服务端口
management.endpoints.web.exposure.include = env,refresh 

3.修改 Application.java

package com.gupao.springcloudclientconfig;

import org.omg.CORBA.Environment;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class SpringCloudClientConfigApplication {

	@Value("${my.name}")
	public String name;
	public static void main(String[] args) {
		SpringApplication.run(SpringCloudClientConfigApplication.class, args);
	}

	@GetMapping("/config")
	public String getConfig(){
		return name;
	}
}

4.测试

http://localhost:8080/config,成功显示 default.

5.修改配置生效

http://localhost:8080/actuator/env -> search ws.properties -> 通过 POST 方法请求 localhost:8080/actuator/refresh 刷新配置文件 , 发现已变更则成功!

6.修改后刷新 bean

在需要修改的类中增加 @RefreshScope 注解,就会开启刷新 @Value 的值
