我不明白发生了什么事。两天前没有问题，现在我无法部署应用程序。任何一个。关于网络，我所做的唯一一件事就是使用以太网线将笔记本电脑插入房屋中的其他插座，仅此而已。我尝试了在这里找到的几乎所有解决方案，但没有任何帮助。

Disconnected from server

当我尝试连接到“
localhost：8080”时，我在日志中收到有关连接被拒绝的消息和“与服务器断开连接”的消息。日志中没有任何有用的内容（无警告/错误）。我的每个JEE应用程序中都存在此问题。

正如我所说的，从这里尝试过许多解决方案，除了更改％JAVA_OPTS％env
var的值之外，因为在Tomcat目录和Catalina.bat中的任何地方都没有’setenv.bat’文件，该变量似乎已正确设置。
我对这种技术还很陌生，我有点害怕开始调整一些我不知道的东西。

是什么导致此问题？有什么可能的解决方案？
