spring里quartz调度的连续触发

   作法是通过spring在执行的触发器的监听器的里面注入下一个要执行的监听器实例，这

样就可以达到连续地触发，而至于具体怎样的触发：比如说什么时候触发，下一个相隔多久才

触发这些则可以通过配置文件进行配置。
 
    这是用于连续触发的Listener:

package com.sww.quartz.listeners;

import org.apache.log4j.Logger;
import org.quartz.JobDetail;
import org.quartz.JobExecutionContext;
import org.quartz.Scheduler;
import org.quartz.Trigger;
import org.quartz.listeners.TriggerListenerSupport;
import org.springframework.scheduling.quartz.QuartzJobBean;
import org.springframework.scheduling.quartz.SimpleTriggerBean;

public class NextJobTriggerListener extends TriggerListenerSupport {
	private  Logger logger = Logger.getLogger(getClass());
	private String name;
	public String getName() {
		return this.name;
	}
	public void setName(String name)
	{
		this.name=name;
	}
	private SimpleTriggerBean nextTrigger;
	public void setNextTrigger(SimpleTriggerBean nextTrigger) {
		this.nextTrigger = nextTrigger;
	}
	@Override
	public void triggerComplete(Trigger trigger, JobExecutionContext context, int code) {
		try{
		logger.debug("Trigger :"+trigger.getGroup()+"."+trigger.getName()+" completed with code:"+code+",next trigger is "+nextTrigger.getGroup()+"."+nextTrigger.getName());
		if(code!=3)return;
		Scheduler schduler=context.getScheduler();
		JobDetail nextJob=nextTrigger.getJobDetail();
		//查找名称和即将加入的任务一样的任务
		JobDetail oldJob=schduler.getJobDetail(nextJob.getName(),nextJob.getGroup());
		//查找名称和即将加入的触发器一样的触发器
		Trigger oldTrigger=schduler.getTrigger( nextTrigger.getName(),nextTrigger.getGroup());
		
		if(oldJob==null&&oldTrigger==null)//同名的任务和触发器都不存在
		{
			logger.debug("inside scheduleJob."+code);
			schduler.scheduleJob(nextJob,nextTrigger);
		}else//同名的任务或触发器
		{
			
			logger.debug("oldJob==null:"+(oldJob==null));
			logger.debug("oldTrigger==null:"+(oldTrigger==null));	
		}
		super.triggerComplete(trigger, context, code);
		}catch(Exception e)
		{
			e.printStackTrace();
		}
	}
	

}

  这是具体怎样触发的spring的配置文件：
