我有一个问题，我使用jhipster生成了3种微服务：网关，uaa和赌博生产者。当我使用docker-compose一起运行3个服务时，它运行良好，然后我停止了赌博生产者服务，并在localhost上为此服务运行./mvnw，当它们一起工作时不起作用。网关无法提供此服务
我尝试过一些情况：
routes:
gamblingproducer:
url: http://localhost:8081
或
routes:
gamblingproducer:
path: services/gamblingproducer/**
serviceId: gamblingproducer
引发异常：Connect to localhost:8081 [localhost/127.0.0.1] failed: Connection refused (Connection refused)

请帮助我谢谢
Localhost始终解析为容器本身的127.0.0.1。将localhost更改为运行eureka的主机ip或容器/服务名称，但不要使用localhost。当容器中的应用程序在分离的远程主机上运行时，请考虑一下。除非要循环回到同一个容器（几乎永远不会发生），否则切勿使用localhost。
更新：
像我说的那样，基于评论部分，问题出在“本地主机”及其处理方式上。据我了解，情况看起来像这样：主机上的mvnw正在连接到docker中的eureka，说：“嗨，我是mnvw，您可以在localhost：8081上与我联系”。但是，eureka在尝试验证时会调用localhost，而您的主机会获得eureka的localhost（即容器）。因此，解决您的问题的方法是使mnvw说出可以通过eureka容器而不是localhost找到的主机名（或ip）。在容器方面，使用localhost非常棘手，所以要注意！
