3、创建SpringCloud server消费者（ribbon

先创建一个普通的SpringBoot项目，然后添加SpringCloud服务消费者所需的配置即可。

pom.xml 添加内容

<!--使用SpringBoot1.5.3版本-->
  <parent>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-parent</artifactId>
       <version>1.5.3.RELEASE</version>
       <relativePath/> <!-- lookup parent from repository -->
   </parent>


<dependencies>

         <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>
       </dependency>

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

</dependencies>

<dependencyManagement>
           <dependencies>
               <dependency>
                   <groupId>org.springframework.cloud</groupId>
                   <artifactId>spring-cloud-dependencies</artifactId>
                   <version>Camden.SR7</version>
                   <type>pom</type>
                   <scope>import</scope>
               </dependency>
           </dependencies>
</dependencyManagement>

application.yml文件配置

 eureka:
  client:
    serviceUrl:
      #指定服务端地址
      defaultZone: http://localhost:8000/eureka/

在启动类中调用在server中已经注册的服务

@EnableDiscoveryClient
@SpringBootApplication
public class SpringclientApplication {

    @Bean
    @LoadBalanced
    RestTemplate restTemplate() {
        return new RestTemplate();
    }

    public static void main(String[] args) {
        new SpringApplicationBuilder(SpringclientApplication.class).web(true).run(args);

}

创建Controller调用服务接口

@RestController
public class MainController {
    @Autowired
    RestTemplate restTemp;

    @RequestMapping("/user/{name}")
    public String get(@PathVariable("name") String name){
        return restTemp.getForEntity("http://db-service:8085/user/" + name, String.class).getBody();
    }
}

运行该项目，在浏览器中输入 http://localhost:8086/user/bin 连接，即可调用接口。
