正如标题所示，我在 Windows 服务中托管了 WCF 服务。当我使用 Visual Studio WCFTestClient 时，GetVersion() 方法（只返回一个字符串）工作正常。当我尝试从 Java 客户端调用相同的方法时，我得到一个无效的主机名错误。
使用 Wireshark 我跟踪了 XML 消息并得到以下信息：

我玩过 Host 参数，使用服务器的完整 DNS 名称，但结果是一样的。这是配置文件：
------配置------

我将 NetBeans 用于 Java 客户端，代码很简单：
------Java代码--------
CommunicatorService service = new CommunicatorService();
ICommunicatorService port = service.getBasicHttp();
((BindingProvider)port).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "http://192.168.201.210:7770/CommunicatorService.svc");
String version = port.getVersion();
任何指针/调试技巧都会有所帮助。我对 Java 不是很熟悉，所以我不确定从哪里开始，但是发送的消息中似乎有些地方是错误的，我可以更改消息或服务的配置以知道会发生什么，我只是不知道那是什么东西。
提前致谢！
