Java Spring MVC控制器死机且没有响应

我面临一些具体问题： 我的rest控制器工作了几个小时，当我向它发出请求时，我不知道为什么。它没有回应。浏览器中的加载过程正在等待响应一段时间。若我用海报发送请求，我可以看到请求被发送到控制器，但并没有收到响应。我试图调试应用程序，我有一些预定的处理-他们正在工作。但不是。请求未到达控制器。它以前卡住了。我怎样才能知道这是在哪里发生的？非常感谢。这是我的控制器类：

我不认为您的控制器有问题，至少在提供的代码中没有证据表明这一点。 这里出现问题的原因有很多，举几个例子：

• HTTP连接池已满 运行您的应用程序的web服务器有一个连接池—许多可用的HTTP连接。 除非您使用的是异步的东西（我想您不会），否则池中可能会出现大量正在运行的连接
