4.3、启动类ConfigServerApplication.java

package com.jacky.cloud;
 
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
@EnableDiscoveryClient
@EnableConfigServer
public class ConfigServerApplication {
  public static void main(String[] args) {
    SpringApplication.run(ConfigServerApplication.class, args);
  }
}

五、客户端（microservice-config-client）

5.1、pom.xml配置文件

5.2、application.yml文件

server:
  port: 8081

View Code

5.3、bootstrap.yml文件

spring:
  cloud:
    config:
      username: jacky123  #configservice认证的用户名
      password: admin123   #认证密码
      label: master   # 仓库的分支节点
      discovery:
        enabled: true
        service-id: microservice-config-service
      profile: dev   #仓库中对应文件的环境，如dev、prod、test等
      fail-fast: true
    bus:
      trace:
        enabled: true  #开启消息跟踪
  application:
    name: microservice-config-client
  rabbitmq:
    host: 192.168.6.130
    port: 5672
    username: myuser
    password: mypass
eureka:
  client:
    serviceUrl:
      defaultZone: http://jacky:[email protected]:9511/eureka
  instance:
    prefer-ip-address: true
management:
  security:
    enabled: false    #刷新时关闭安全认证

注意：

上面这些属性必须配置在bootstrap.yml，服务端的配置内容才能正确加载。因为通过bootstrap.yml的加载优先级比配置中心的服务端的高，服务端加载优先于application.yml，所以如果你把上面的配置写在application.yml中，相当于默认不是从配置中心的服务端中读取的配置信息，而是spring boot的默认加载。启动的时候就会看到加载的配置，不是配置中心得配置内容，而是默认的本地的

5.4、启动类（ConfigClientApplication.java）

package com.jacky.cloud;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
 
@SpringBootApplication
@EnableDiscoveryClient
public class ConfigClientApplication {
  public static void main(String[] args) {
    SpringApplication.run(ConfigClientApplication.class, args);
  }
}

5.5、控制层类（ConfigClientController.java）

package com.jacky.cloud.controller;
 
import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
 
@RefreshScope
@RestController
public class ConfigClientController {
 
  @Value("${profile}")
  private String profile;
 
  @GetMapping("/profile")
  public String getProfile() {
    return this.profile;
  }
}

六、在码云创建git项目，放置配置文件
