我目前正在开发该公司的简单的局域网聊天功能。但我坚持在这一点上运行方法永远不会执行在客户端，以前工作正常。它重构了构造函数以便能够在系统托盘图标上双击可配置和可视框架后开始工作。请让我知道我出错的地方。我向您发送之前正在工作的代码以及现在不适用的代码。如果需要，我也可以发送服务器接口源代码和其他代码。Run方法从未得到执行

任何帮助将非常感激。干杯!
在哪里登录类，和你在做什么在登录（）构造函数。因为，你必须在Login（）内部启动线程来执行运行。 –
好的，我添加了login.java。我在它的构造函数中调用ChatClient对象。我会尝试上传服务器和其他你需要的类来让它运行。无论如何感谢您的回复。干杯! –
我试图与你们共享服务器源，但第一个帖子不允许我发布超过30000个字符。我需要另外5000个字符的服务器和其他类。我们有其他选择或分享方式吗？提前致谢。 –
