连接池使用Glassfish和Apache DBCP与Spring挂起

时间：2010-04-15 14:56:39

标签： spring glassfish apache-commons-dbcp

我们有一个Spring应用程序，它使用Apache DBCP进行连接池。我们的应用程序已经生产了近一年没有任何问题。但是，在过去几周内，该应用程序已冻结多次。 （通过冻结，我的意思是没有处理请求。）通过重新启动托管应用程序的Glassfish域来暂时解决问题。

我们正在监视此应用程序的内存（堆+非堆）和CPU利用率。这里似乎没有什么不寻常的。但是，我们注意到，当我们重新启动域时，我们会在日志文件中收到类似于此帖子底部的异常消息。

我指出我们正在使用DBCP，因为每个NPE都会在堆栈顶部报告borrowObject方法。在任何应用程序关闭期间，它们中的每一个都在相同的毫秒内发生。

我们注意到过去发生了一些这样的事情（关闭了这样的NPE），但是当应用程序冻结时，总会有五个。这个，我们不相信巧合，是处理对应用程序的请求的相同数量的HTTPSSLWorkerThreads。

如果有人知道造成这种情况的原因，以及如何解决这个问题，那将非常感谢帮助。

不幸的是，DBCP臭名昭着，尽管最近还有重写努力。或者，您可以尝试使用（更快）不同的池，例如BoneCP：http://jolbox.com。
