1pom.xml引入依賴

		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-eureka</artifactId>
		</dependency>

2注入DiscoveryClient物件

@RestController
public class HelloController {

	private final Logger logger = Logger.getLogger(getClass());

	@Autowired
	private DiscoveryClient client;

	@RequestMapping(value = "/hello", method = RequestMethod.GET)
	public String hello() throws Exception {
		ServiceInstance instance = client.getLocalServiceInstance();

		logger.info("/hello, host:" + instance.getHost() + ", service_id:" + instance.getServiceId());
		return "Hello World";
	}
}
 

3主類加上@EnableDiscoveryClient註解

@EnableHystrix
@EnableDiscoveryClient
@SpringBootApplication
public class HelloApplication {

	public static void main(String[] args) {
		SpringApplication.run(HelloApplication.class, args);
	}

}

4application.properties配置

spring.application.name=hello-service

eureka.client.serviceUrl.defaultZone=http://localhost:1111/eureka/
 

5啟動服務註冊中心和hello-service，可以在Eureka資訊面板看到註冊資訊
