1.导入jar包

2.配置applicationContext.xml文件

<!-- 任务调度1 --><!-- bean id="simpleJob" class="com.shprj.quartz.SimpleJob"></bean><bean id="simpleJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"><property name="targetObject" ref="simpleJob"></property><property name="targetMethod" value="showTime"></property></bean><bean id="simpleTrigger"  class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean"><property name="jobDetail" ref="simpleJobDetail" /><property name="startDelay" value="1000" /><property name="repeatInterval" value="2000" /></bean><bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"><property name="jobDetails"><list><ref bean="simpleJobDetail"/></list></property><property name="triggers"><list><ref bean="simpleTrigger"/></list></property></bean--><!-- 任务调度2 --><!-- bean id="firstJobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean"><property name="jobClass" value="com.shprj.quartz.FirstJobDetail"></property></bean><bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">  <property name="jobDetail" ref="firstJobDetail" />  <property name="cronExpression" value="0/5 * * ? * *" />  </bean> <bean  class="org.springframework.scheduling.quartz.SchedulerFactoryBean"><property name="triggers"><list><ref bean="cronTrigger"/></list></property></bean--><!-- 任务调度3 注解 --><task:annotation-driven />

一共三种配置方法

1.

applicationContext.xml:

//simpleJob指定任务操作
< bean id="simpleJob" class="com.shprj.quartz.SimpleJob"></bean><bean id="simpleJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"><property name="targetObject" ref="simpleJob"></property><property name="targetMethod" value="showTime"></property></bean><bean id="simpleTrigger"  class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean"><property name="jobDetail" ref="simpleJobDetail" /><property name="startDelay" value="1000" />开始时间<property name="repeatInterval" value="2000" />间隔时间</bean><bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"><property name="jobDetails"><list><ref bean="simpleJobDetail"/></list></property><property name="triggers"><list><ref bean="simpleTrigger"/></list></property></bean>

simpleJob.java：

package com.shprj.quartz;import java.util.Date;public class SimpleJob {public void showTime(){System.out.println("简单任务1："+new Date().toLocaleString());}}

Tomcat启动就会自动执行

2.

applicationContext.xml:

<bean id="firstJobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean"><property name="jobClass" value="com.quartz.FirstJobDetail"></property></bean><bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"><property name="jobDetail" ref="firstJobDetail" /><property name="cronExpression" value="0 0 20 * * ?" />这里写cron表达式</bean><bean  class="org.springframework.scheduling.quartz.SchedulerFactoryBean"><property name="triggers"><list><ref bean="cronTrigger"/></list></property></bean>

firstJobDetail.java:

package com.quartz;import java.util.Date;import com.dao.PianoRecordDao;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;public class FirstJobDetail extends QuartzJobBean {@Overrideprotected void executeInternal(JobExecutionContext arg0) throws JobExecutionException {PianoRecordDao pianoRecordDao = new PianoRecordDao();int i = pianoRecordDao.insert();System.out.println("Quartz任务执行！");}}

Tomcat启动自动执行

3.没看，，以后写
