Question

我的问题是，当我使用以下方法从控制器执行作业时：

def startScheduler(){
        Scheduler scheduler = new StdSchedulerFactory().getScheduler();
        ///////////////////////////////
        JobDetail job = JobBuilder.newJob(SchedulerJobService.class)
        .withIdentity("SendMailJob","DB")
        .build();
        ///////////////////////////////
        Trigger trigger = TriggerBuilder
        .newTrigger()
        .withIdentity("crontrigger","DB")
        .withSchedule(CronScheduleBuilder.cronSchedule(cronSce))
        .build();
        scheduler.start();
        scheduler.scheduleJob(job, trigger);
}

通话：

class SchedulerJobService implements Job {  
    private static final log = LogFactory.getLog(SchedulerJobService.class) 

    boolean transactional = true

    public void execute (JobExecutionContext jobExecutionContext) { 
       new SendMailController().sendMail()  
       }
    }

在方法sendMail() for中执行循环，发送大量邮件，当我执行stopScheduler()时：

public def stopScheduler(){
        Scheduler scheduler = new StdSchedulerFactory().getScheduler();
        TriggerKey triggerKey = TriggerKey.triggerKey("crontrigger","DB");
        scheduler.unscheduleJob(triggerKey);
    }

作业停止，但for中的new SendMailController().sendMail()继续他的工作，直到它最终完成。如何在执行stopSceduler()时停止它？

我用DB（Grails中的Domain）解决了这个问题。在sendMail()方法中，我有：

     def sendMail(correoList, nombreList){
                    int index = correoList.size()

                    try{
                        for(int i = 0; i < index; i++){
                            def tcp = TemplateControlPanelText.get(1)
                            if(!tcp.enviando){
                                break;  
                           }
                         .....
                     }
             }catch(Exception e){
        }
   }

一开始：

def startScheduler(){
        def t = TemplateControlPanelText.get(1)
        t.enviando = true
        t.save(flush:true)
        Scheduler scheduler = new StdSchedulerFactory().getScheduler();
      .....
}

最后当我停止工作时：

public def stopScheduler(){
        Scheduler scheduler = new StdSchedulerFactory().getScheduler();     
        TriggerKey triggerKey = TriggerKey.triggerKey("crontrigger","DB");
        scheduler.unscheduleJob(triggerKey);
        def t = TemplateControlPanelText.get(1)
        t.enviando = false
        t.save(flush:true)
    }

停止在JobService Groovy中执行的所有作业
