Java 当传递多个文件时，Swing窗口被卡住

我正在创建一个代码审查应用程序，它接受

.resource

格式化文件并共享结果。它适用于

.resource

格式文件中的3-4个文件夹，但当文件夹大小增加时，窗口会卡住

枚举似乎类似错误发生在我无法复制的某些代码中。我看到您的应用程序正在多个线程中处理这些文件（从pmdConfiguration.setThreads（4）行判断）。您是否检查了这些线程中是否存在任何异常（如OutOfMemory）？还要注意，您不应该在操作侦听器本身中进行任何主要处理，因为这会阻塞整个UI。只需调用new Thread（）{your processing}.start（）也可以，我个人从不使用SwingWorker。没有例外，如果我打开窗口让程序运行，它将在30-40分钟内完成。那么可能这就是它需要多长时间？如果总是在单独的线程中进行处理，那么Swing应该不会有任何问题。您可以使用JProgressBar在进度。如果您准确地说明了您的期望与现在发生的事情，以及一个我也可以运行的解决该问题的代码，可能会有所帮助。您是否尝试过使用publish（）方法，然后在工作线程中重写process（）方法，而不是使用setprogress来显示信息？也许您可以在那里打印或显示您需要的内容
