Spring clouud eureka feign调用问题

最近在学习使用spring cloud 的时候遇到这样一个问题，项目划分了3个模块注册中心、服务提供方、服务消费方.
分别启动3个项目后在注册中心的web管理页面能看到服务提供方和服务消费方都已经注册上来了。但是当服务消费方调用方法时，通过日志看到是以服务提供方的别名为IP地址发起调用的一调用就报错请各位大神们帮忙看看最好能给我讲讲为什么会出现这个问题

注册中心启动类

 * 注册中心启动类
 *
 */
@EnableEurekaServer
@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

注册中心配置

server.port=8001
#自我注册
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
#
eureka.server.enable-self-preservation=true
eureka.server.eviction-interval-timer-in-ms=60000

#关闭自我保护
eureka.server.enableSelfPreservation=false

eureka.client.serviceUrl.defaultZone=http://localhost:${server.port}/eureka/

服务提供方启动类

@EnableDiscoveryClient
@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

服务提供方Rest接口

@RequestMapping("menu")
public class BMenuController {
    @Autowired
    private IBMenuService menuService;

    private static final Logger logger = LoggerFactory.getLogger(BMenuController.class);

    @RequestMapping("/selectById/{id}")
    public BMenu selectById(@PathVariable("id") Integer id) {
        logger.info("数据访问层  菜单通过ID获取 调用  id:[{}]", id);
        return menuService.selectById(id);
    }

服务提供方配置：

spring.application.name=ic-generic
#服务注册的Eureka Server地址
#eureka.client.serviceUrl.defaultZone=http://hlwic:hlwic@localhost:8001/eureka
eureka.client.serviceUrl.defaultZone=http://localhost:8001/eureka

server.port=8002

服务消费方启动类：

@EnableDiscoveryClient
@EnableFeignClients
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

服务消费方 feign接口：

@FeignClient("ic-generic")
public interface IBMenuService {

    @RequestMapping("/menu/selectById/{id}")
    public BMenu selectById(@PathVariable("id") Integer id);

服务消费方配置：

spring.application.name=ic-app
server.port=8005
eureka.client.serviceUrl.defaultZone=http://localhost:8001/eureka/

异常信息：
