仅针对REST请求获取从一个docker容器到另一个容器的连接被拒绝错误

我有两个docker容器apiserver和loginserver。它们都提供RESTAPI，并使用SpringBoot构建。我创建了一个名为my network的网桥网络，两个容器都连接到同一个网桥。 我通过交互式shell从apiserver ping了loginserver，它是可访问的。我从主机发出REST请求，以便知道套接字已暴露。但是，当我从apiserver向loginserver发出相同的REST请求时，我得到了错误：

: HttpQueryService::uri=http://172.28.0.7:8090/users/login
2018-06-19 19:08:24.196 ERROR 7 --- [nio-9000-exec-3] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception

org.apache.http.conn.HttpHostConnectException: Connect to 172.28.0.7:8090 [/172.28.0.7] failed: Connection refused (Connection refused)

以下是我的网络的详细信息：

端口8090是否由loginserver映像公开？用于检查输入命令

docker images 

然后查找登录服务器映像的ImageID。然后输入命令

docker inspect image {Login server image id}

---

在输出中，检查ExposedPorts是否显示8090

登录服务器映像是否显示端口8090？用于检查输入命令

docker images 

然后查找登录服务器映像的ImageID。然后输入命令

docker inspect image {Login server image id}

在输出检查ExposedPorts中，如果8090向参与方公开或未公开，但我只是在我的系统上通过将获取REST请求的地址设置为：

---

例如：

http://217.114.203.196/myrequest

派对迟到，但我只是在我的系统上通过设置从以下地址获取剩余请求来解决这个问题：

例如：

http://217.114.203.196/myrequest

您的loginserver映像是否暴露了8090端口？要检查，请键入命令

docker images

，然后查找登录服务器映像的

ImageID

。然后输入命令

docker inspect image{Login server image id}

。在输出检查中，

ExposedPorts

就是这样！8090没有暴露。请回答这个问题。我会接受的！端口8090是否由loginserver映像公开？要检查，请键入命令
