unlock（）永远不会被调用但是使用try..finally

标签： java multithreading servlets

我正在使用servlet（大气框架和自定义框架），它们都使用相同的ReentrantLock来同步某些操作。我得到了令人困惑的行为，一个线程一次又一次地进入锁定而没有调用unlock()匹配其先前的lock()。

出于调试目的，我在lock()调用之后添加了堆栈跟踪的转储，它总是显示相同的输出。这是不是意味着，我的方法一次又一次地被调用，但后续的try...finally永远不会被执行？

IManagerLock batchLock = _lockManager.getManagerLock(true);
try {
    // ...do something - in this case the code won't try to lock() again
}
finally {
    batchLock.unlock();
}

getManagerLock()将获取锁并在锁周围返回一些包装器对象，这允许我执行一些调试等。将UUID分配给包装器对象，该对象将打印到lock()和unlock()上的日志中。

以下是有线堆栈跟踪的示例。重复七次。如您所见，只有Locked: xxx但不是Unlocked: xxx消息。

知道发生了什么事吗？你能解释一下如何在不完全执行函数体的情况下一次又一次地执行同一个线程吗？没有释放锁？

编辑12.11.2015 19:56：正如评论中所述：http-/0.0.0.0:8080-13是主题的名称。所以我确定它是再次执行的相同线程。

编辑13.11.2015 09:38：正如评论中所述：我正在使用JBoss 7.1.3.Final和JBossWeb 7.0.17.Final。 AtmosphereServlet使用asyncSupported=true而自定义服务不使用。{/ p>

答案 0 :(得分：1)

我找到了这种行为的解决方案：涉及一个（CDI）bean，由于某种原因无法创建。在我的日志消息之后和try-block之前抛出异常。但随着大气框架的发现，它在日志中不可见。如果框架设置为debug级别（未在生产服务器上设置），框架本身将仅将其打印到日志中。

一个非常愚蠢的自我造成的错误！
