Spring cloud DiscoveryClient未看到来自Eureka的服务

当我向eureka询问它所知道的服务时（localhost:8071/eureka/apps/），它说有3项服务上线了：

）上面写着2-路由器和订单，但没有前端

有人知道原因是什么吗

作为提示，WEBFRONT应用程序是一个带有eureka插件的nodejs应用程序。路由器和订单都是靴子。
显然，前端注册正确，尤里卡认为这是正确的。我将eureka XML输出逐行与订单和前端进行了比较，并没有发现任何重大差异…
我发现前端服务的
vipAddress
字段是
true
，但我认为在您的情况下应该是
FRONTEND
或
FRONTEND
。因为在引擎盖下，
EurekaDiscoveryClient
使用
com.netflix.discovery.EurekaClient getInstancesByVipAddress（String，bool）
函数（）通过其
vipAddress
查询可用服务

更改后，您应该可以在路由器服务的
/service instances/frontend
路径的响应中看到该服务。
您可以将前端项目的eureka设置包括在内吗？谢谢，就是这样。我不知道它一定是平等的！你是怎么换这件女裙的？这可以通过Spring属性文件完成吗？我试过eureka.instance.vipAddress，但没用。。。
