• 配置文件

    spring.application.name=eureka-client
    server.port=2222
    eureka.instance.hostname=localhost
    #服务注册中心
    eureka.client.serviceUrl.defaultZone=http://localhost:1111/eureka/
  

• Application.java

    @EnableDiscoveryClient
    @SpringBootApplication
    public class Application {
    
        public static void main(String[] args) {
            new SpringApplicationBuilder(Application.class).web(true).run(args);
        }
    }
  

@EnableDiscoveryClient开启了服务发现

• controller

    @RestController
    public class DemoController {
    
        Logger logger = LoggerFactory.getLogger(this.getClass());
        @Autowired
        DiscoveryClient  discoveryClient;
        @GetMapping("/hello")
        public String hello(){
    
            logger.info("service:"+ discoveryClient.getServices());
            return "hello world";
        }
    }
