Memory leaks 竹部署将等待Grails没有Quartz作业

我正在使用竹子构建、测试和部署对服务器的提交。然而，每隔一段时间，我就会在Tomcat端得到一个失败的部署。竹不知道发生了什么，所以当应用程序不能正常启动时，我必须运行一个手动构建

据我所知，这是由于运行Quartz任务。有没有一种方法可以安全地部署战争，但要等到所有的工作都完成了？在部署之前，最好先取消部署计划

我已经调出我的Catalina日志来强调这个问题：

您是对的，Quartz调度程序不会停止为运行作业而创建的线程（工作线程池）。当应用程序关闭时，您需要调用方法。我很惊讶GrailsQuartz插件没有为您做这件事

发生这种情况还有其他原因。您可能有一些正在运行的作业，而Quartz挂起等待它们完成（即使在调用适当的关机时）。Tomcat不耐烦，在中间杀死了整个东西。签出（）

org.quartz.scheduler.interruptJobsOnShutdown

和

org.quartz.scheduler.interruptJobsOnShutdownWithWait

选项

请注意，这对您没有帮助，因为您没有关闭整个JVM，只是取消部署一个应用程序

此外，错误消息将

Thread-212

列为原因之一。这很可能是您的自定义线程（总是命名线程！），它也必须被中断

另见

如何命名线程？我在grails中有两个quartz作业，但我不知道如何命名它们。@johngitta:quartz为他的线程命名，例如

quartzScheduler\u Worker-N

。但我在你的应用程序中看到了

Thread-212

。它不是由您创建的，就是由某个库创建的。看看，成功！谢谢你，先生。这需要一些额外的挖掘，但在过去的5个小时里，在过去的15次部署中，测试都取得了成功。@johngitta:很高兴听到这个消息。你能进一步解释一下问题是什么以及你是如何解决的吗？第一个问题是石英配置没有创建，所以我添加了缺少的内容。然后将

waitForJobsToCompleteOnShutdown

标志设置为true。
