先創(chuàng)建一個(gè)普通的SpringBoot項(xiàng)目，然后添加SpringCloud服務(wù)消費(fèi)者所需的配置即可。

pom.xml 添加內(nèi)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>

         <dependency>
               <groupId>org.springframework.cloud</groupId>

               <dependency>

                   <version>Camden.SR7</version>
                   <type>pom</type>
                   <scope>import</scope>
               </dependency>
           </dependencies>
</dependencyManagement>

application.yml文件配置

 eureka:
  client:
    serviceUrl:
      #指定服務(wù)端地址
      defaultZone: http://localhost:8000/eureka/

在啟動(dòng)類中調(diào)用在server中已經(jīng)注冊的服務(wù)

@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);

}

創(chuàng)建Controller調(diào)用服務(wù)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();
    }
}

運(yùn)行該項(xiàng)目，在瀏覽器中輸入 http://localhost:8086/user/bin 連接，即可調(diào)用接口。
