##更改配置
13+
14+
增加如下配置：
15+
16+
```groovy
17+
dependencies {
18+
//...
19+
20+
compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-client')
21+
22+
//...
23+
}
24+
```
25+
26+
##一个最简单的 Eureka Client
27+
28+
```java
29+
@SpringBootApplication
30+
@EnableDiscoveryClient
31+
@RestController
32+
publicclassApplication {
33+
34+
@RequestMapping("/")
35+
publicStringhome() {
36+
return"Hello world";
37+
}
38+
39+
publicstaticvoidmain(String[]args) {
40+
SpringApplication.run(Application.class, args);
41+
}
42+
}
43+
```
44+
45+
项目配置：
46+
47+
```
48+
spring.application.name: micro-weather-eureka-client
49+
50+
eureka.client.serviceUrl.defaultZone: http://localhost:8761/eureka/
51+
```
52+
53+
##运行
54+
55+
分别在 8081 和 8082 上启动了客户端示例。可以在 Eureka Server 上看到这两个实体的信息。
