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 {

	@Override

	protected 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
