【springCloud基础篇-11】Spring Cloud Config 配置中心之refresh与SVN示例(他人的博客地址)

接上篇文章。

SVN示例的博客地址:http://www.ityouknow.com/springcloud/2017/05/23/springcloud-config-svn-refresh.html

refresh:

客户端client项目添加依赖:

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

修改配置文件(application.yml)注意关闭权限:

server:
  port: 9021
eureka:
  client:
    service-url:
      defaultZone: http://peer1:8000/eureka/,http://peer2:8001/eureka/,http://peer3:8002/eureka/
spring:
  application:
    name: spring-cloud-config-client
management:
  security:
    enabled: false #springboot 1.5.X 以上默认开通了安全认证

 

控制器添加注解@RefreshScope:

package com.example.spirngcloudconfigclient.web;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @ProjectName: spirng-cloud-config-client
 * @Package: com.example.spirngcloudconfigclient.web
 * @ClassName: HelloController
 * @Author: MC
 * @Description: ${description}
 * @Date: 2019/11/15 0015 11:45
 * @Version: 1.0
 */
@RestController
@RefreshScope // 使用该注解的类,会在接到SpringCloud配置中心配置刷新的时候,自动将新的配置更新到该类对应的字段中。
public class HelloController {

    @Value("${native.hello}")
    private String hello;

    @RequestMapping("/hello")
    public String from() {
        return this.hello;
    }
}

 

测试:

先访问http://localhost:9021/hello

返回的是hello_i_im_mysql

 修改server项目中的mysql配置文件:

native.hello=hello_i_im_mysql_update

重启server项目。

cmd命令执行:curl -X POST http://localhost:9021/refresh返回结果如图:

再次访问浏览器:http://localhost:9021/hello
