SpringCloudConfig简单使用

动态修改配置文件信息，避免每次改动都需要发版的问题

SpringCloudConfig是一个分布式的配置管理方案，包含了server端和client两个部分,同时我们需要创建个git仓库，这个仓库就是放配置文件的信息，如下图所示

在我们完成了如图所示的操作后，现在开始创建服务端

server.port=9006

package com.config;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.config.server.EnableConfigServer;
 
/**

@SpringBootApplication
/**

 */
@EnableConfigServer
/**

 */
@EnableDiscoveryClient
public class ConfigApplication {
    public static void main(String[] args) {
        SpringApplication.run(ConfigApplication.class,args);
    }
}

　　到这里服务端的就创建完成了，下面开始客户端的

　　如果我们git修改的文件生效，需要使用@RefreshScope，使用方式如下图所示
