    @SpringBootApplication
    @EnableConfigServer // 开启ConfigServer
    public class ConfigServer_3344 {
        public static void main(String[] args) {
            SpringApplication.run(ConfigServer_3344.class,args);
        }

  2. 新建Module为springcloud-config-eureka-7001

    复制springcloud-eureka-7001内容到这个Module

    修改主启动类名字为ConfigEurekaServer_7001

  3. 在pom中引入依赖(原本复制的依赖不变)

  5. 运行3344、ConfigEurekaServer_7001，进行测试

    http://localhost:7001/ 可以访问说明配置ok

  6. 新建Module为springcloud-config-dept-8001

    复制springcloud-provider-dept-8001内容到这个Module

    修改主启动类名字为ConfigDeptProvider_8001
