本篇接于上篇[《SpringBoot：Eureka搭建注册中心》][SpringBoot_Eureka]

*  pom文件

<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
    
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

*  配置文件

eureka:
      client:
        serviceUrl:
          defaultZone: http://localhost:20000/eureka/
    server:
      port: 30002
    spring:
      application:
        name: eureka-client

*  Application

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

*  我们创建一个Controller用于测试

@RestController
    @Slf4j
    public class Controller { 
    
        @Value("${server.port}")
        private String port;
    
        @PostMapping("/sayHi")
        public Friend sayHiPost(@RequestBody Friend friend) { 
            log.info("You are " + friend.getName());
            friend.setPort(port);
            return friend;
        }
    
    }

@Data
    public class Friend { 
    
        private String name;
    
        private String port;
    
    }

启动项目，查看Eureka的管理页面，可以看到我们刚启动的服务提供方

我们使用postman测试一下`localhost:30002/sayHi`接口

到这里，client的搭建就完成了。
