spring环境：

 JOB类

package com.chenjun.quartz_1.springenv;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;import org.springframework.scheduling.quartz.QuartzJobBean;public class SimpleJob extends QuartzJobBean{	@Override	protected void executeInternal(JobExecutionContext context) throws JobExecutionException	{		String message = context.getJobDetail().getJobDataMap().getString("message");		System.out.println(message);	}}

JobDetail类

package com.chenjun.quartz_1.springenv;import java.text.ParseException;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.quartz.CronExpression;import org.quartz.CronTrigger;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;import org.quartz.Scheduler;import org.quartz.SchedulerException;import org.quartz.StatefulJob;import org.quartz.impl.StdScheduler;public class CronJobDetail implements StatefulJob{	/*** 日志 */	private static final Log LOG = LogFactory.getLog(StatefulJob.class);			public void execute(JobExecutionContext context) throws JobExecutionException	{		StdScheduler stdScheduler = (StdScheduler)context.getScheduler();		CronTrigger cronTrigger = (CronTrigger)context.getTrigger();		System.out.println("JOB执行.."+cronTrigger.getCronExpression());				CronTrigger  trigger = null;		try		{			trigger = (CronTrigger) stdScheduler.getTrigger("cronJobTrigger", Scheduler.DEFAULT_GROUP);						CronTrigger newTriggerIns = new CronTrigger();			newTriggerIns.setJobName(cronTrigger.getJobName());			newTriggerIns.setName("abc");			//模拟从数据库里面查出的时间表达式			newTriggerIns.setCronExpression(new CronExpression("0/5 * * * * ?"));			stdScheduler.rescheduleJob("cronJobTrigger", null, newTriggerIns);		}		catch (SchedulerException e)		{			e.printStackTrace();		}		catch (ParseException e)		{			e.printStackTrace();		}	}}

 启动类:

package com.chenjun.quartz_1.springenv;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class SimpleSpringQuartz{	public static void main(String[] args)	{		ApplicationContext ctx = new ClassPathXmlApplicationContext("spring.xml");	}}

结果：

搞定了
