Spring @Scheduled注释

Question

如何动态地使用Spring的@Scheduled注释？

CronTrigger(String expression, TimeZone timeZone)

http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/scheduling/support/CronTrigger.html#CronTrigger-java.lang.String-java.util.TimeZone-

由于我在数据库中有多个时区,我该如何动态传递它们？

我在我的代码中试过这个:

TimeZone timezone = null;
String timezone1 = null;
public SchedulerBean(String timezone2) 
{
     this.timezone1 = timezone2;
  //constructor
}

@Scheduled(cron="0 0 8 * * ?", zone =timezone.getTimeZone(timezone1) ) //Error at this line
public void sendQuestionNotif() 
{
  //......code
}

这是我得到的错误,

*Type mismatch: cannot convert from TimeZone to String*

请帮我.因为我想根据时区触发cron.TIA.

注释参数不能动态设置.您可以通过编程方式执行此操作

class Scheduler implements Runnable {
    public Scheduler(TaskScheduler scheduler, String timezone, String cron) {
        scheduler.schedule(this, new CronTrigger(cron, TimeZone.getTimeZone(timezone)));
    }

    @Override
    public void run() {
        //
    }
}
