我们运行的应用程序基于 Struts 2.0。我们中的许多人同时访问此应用程序。每天晚上大约在同一时间，应用程序都会大量出现。如果我们在浏览器上重新加载应用程序，它永远不会移动到登录页面之前。查看服务器的日志，我可以看到最后一条消息是“线程睡眠”。

在做一些研究时，我遇到了 Spring 框架注释的使用。Struts2 也一样吗？如果可能的话，你能否在struts文件中说明用途？

这与 Struts/Spring 无关。

容器 WAS 说它无法从连接池中获取连接。

在数据源上指定了 Connectiontimeout 时间段。如果在等待那段时间之后，如果 WAS 运行时无法为您的应用程序提供来自池的连接，那么它会抛出此异常。

您必须找出谁在持有池中的连接并确保释放连接。

使用此跟踪字符串 ConnLeakLogic=finest 打开跟踪。发生此异常时，它将转储列出当时正在使用连接的所有线程的状态。这应该是你的起点。
