如何解决本地服务器上的SocketException
我的本地设置有问题。该项目使用Java编写的GUI，该GUI通过Http隧道连接到后端部分。该服务器是Wildfly 19，并且可以正常启动。 每种设置似乎都是正确的，每个必要的文件都在其位置，但是在调用Http隧道类时出现“套接字已关闭”异常。该代码不会错误地关闭套接字，并且对其他所有人都有效，因此在我的本地计算机上一定有错误的配置。
这是来自GUI的日志：

这在我启动GUI时显示在开头。但是，它连接到数据库并成功执行查询。写操作给我各种错误，可能都是由于套接字被关闭导致的。
我不知道什么原因关闭了插座，为什么。它肯定不在代码中，因为它适用于其他人。
尝试用Wireshark分析它是否值得？还有其他想法吗？
谢谢。
