Jax-ws java.net.ConnectException：连接被拒绝
我在使用 JAX-WS (Metro) 从 Tomcat 上运行的 Java 客户端连接到 glassfish 上运行的 Web 服务时遇到奇怪的网络问题。这是场景...
- 两台服务器都在我的本地计算机上运行。
- 如果我将客户端配置为使用 127.0.0.1 连接到 WS 端点，则该请求可以正常工作。
- 如果我将客户端配置为使用我的 IP 地址连接到 WS 端点，我会立即收到 java.net.ConnectException：连接被拒绝。如果我使用我的主机名，也会发生同样的事情。
奇怪的是，如果我从 SoapUI 访问端点，并且使用 127.0.0.1、我的 IP 地址或我的主机名，则请求可以正常工作。
这是我遇到的例外...

I'm experiencing an odd networking problem connecting to a web service running on glassfish from a java client running on tomcat using JAX-WS (Metro). Here's the scenario...
- Both servers are running on my local machine.
- If I configure the client to connect to the WS endpoint using 127.0.0.1, the request works fine.
- If I configure the client to connect to the WS endpoint using my IP address, I immediately get java.net.ConnectException: Connection refused. The same thing happens if I use my hostname.
The odd thing is that if I hit the endpoint from SoapUI, the request works fine if use 127.0.0.1, my IP address or my hostname.
Here's the exception I'm getting...

在 Linux 机器上运行 JAX-WS Web 服务时，我也遇到过类似的问题，其中
/etc/hosts中有一个条目将计算机的主机名指向 localhost。这似乎会导致 JAX-WS Web 服务在
http://localhost:port/endpoint上启动，因此只能从该计算机访问。I have seen a similar problem when running the JAX-WS webservice on a linux box with an entry in
/etc/hoststhat points the computer's hostname to localhost.This seems to cause the JAX-WS webservice to be started on
http://localhost:port/endpointand therefore only be accessible from that machine.“连接被拒绝”意味着没有任何内容在侦听您指定的 IP:端口。其中之一或两者都是错误的。
'Connection refused' means that there is nothing listening at the IP:port you specified. One or both of them is wrong.
