我已经使用grailswar生成了war文件，并在tomcat服务器上部署了这个war文件。我有来自grails的默认调度器和在java quartz中使用quartz的自定义调度器。属性文件在资源中定义。嗯，它工作得很好，但是当我关闭服务器时，它在关闭线程时显示出一些问题。
我有grails schedulejob，它每分钟运行一次，执行一个java类，这个java类读取数据库，并基于信息使用quartz调度新作业。石英调度器一直在调度新作业，无法关闭石英调度器grailsscheduler（触发器）->javaclass（石英调度器）。grails调度器持续运行并触发使用quartz调度器的java类，当我关闭tomcat时，quartz线程仍然处于活动状态，我无法调用quartz调度器关闭方法。我们只能在用户关闭tomcat服务器时调用quartz scheduler shutdown方法，但不知道如何关闭？
grailscode：

class ScheduleJob {     static triggers = {        simple repeatInterval: 100000 // execute job once in 1 minute     }      def execute() {                 new ScheduleIBJob().schedule()           } }

整个java代码的一部分，

public static Scheduler scheduler = null;   public static Scheduler getSchedulerJobObject() throws SchedulerException {         if (scheduler == null) {            scheduler = new StdSchedulerFactory().getScheduler();           scheduler.start();          }               return scheduler;   }

这是一个错误
