 Quartz是一个类似springtask的启动定时任务的框架。spring整合quartz的步骤如下：
一 导入spring和Quartz的坐标

二 编写job     实现Job接口，定义需要定时执行的任务

public class HelloJob implements Job {            public void execute(JobExecutionContext context)                          throws JobExecutionException {                  System.out.println( "定时执行的任务" );          }   }

三 编写spring整合quartz配置文件

<!-- job -->           < bean id = "helloJob"                   class = "org.springframework.scheduling.quartz.JobDetailFactoryBean" >                   < property name = "jobClass" value = "cn.itcast.quartz.job.HelloJob" />           </ bean >                      <!-- trigger -->           < bean id = "simpleTrigger"                   class = "org.springframework.scheduling.quartz.SimpleTriggerFactoryBean" >                   < property name = "jobDetail" ref = "helloJob" />                   <!-- 3秒后第一次执行 -->                   < property name = "startDelay" value = "3000" />                   <!-- 5秒后重复执行 -->                   < property name = "repeatInterval" value = "5000" />           </ bean >                      <!-- scheduler  -->           < bean class = "org.springframework.scheduling.quartz.SchedulerFactoryBean" >                   < property name = "jobFactory" ref = "jobFactory" />                   < property name = "triggers" >                           < list >                                   < ref bean = "simpleTrigger" />                           </ list >                   </ property >           </ bean >
