我正在使用 Bamboo 构建、测试和部署提交到服务器。但是，每隔一段时间，我就会在 Tomcat 端部署失败。Bamboo 不知道发生了这种情况，因此当应用程序无法正常启动时，我必须运行手动构建。

据我所知，这是由于运行 Quartz 任务所致。有没有办法安全地部署 WAR 但要等到所有工作都完成？在部署之前先制定计划是否更好？

我已经提取了我的 Catalina 日志以突出显示该问题：

没错，Quartz 调度程序不会停止为运行作业（工作线程池）而创建的线程。您需要QuartzScheduler.shutdown(boolean)在应用程序关闭时调用方法。我很惊讶 Grails Quartz 插件不适合你。

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并且 Quartz 挂起等待它们完成（即使调用了正确的关闭）。Tomcat不耐烦，在中间杀死了整个事情。检查（未编码？）org.quartz.scheduler.interruptJobsOnShutdown和org.quartz.scheduler.interruptJobsOnShutdownWithWait选项。

请注意，这ShutdownHookPlugin对您没有帮助，因为您没有关闭整个 JVM，而只是取消部署一个应用程序。

错误消息也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。
