一、通过配置实现

1、编写Java类文件，如下两个Java类文件。

import java.util.Date;

public class QuartzJob {

	public void work() {
		System.out.println("QuartzJob is time to run :" + new Date().toString());
	}

}




import java.util.Date;


public class QuartzTest {
	
	//到了某个时刻就会被调用
	public void autoRun() {
		System.out.println("It's time to run :" + new Date().toString());
	}

}

2、添加配置文件，

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.xsd
    http://www.springframework.org/schema/task
    http://www.springframework.org/schema/task/spring-task-3.0.xsd">
    
    <!-- 定时任务bean -->
    <bean name="quartzTest" class="com.zxgs.task.QuartzTest" />
    <bean name="quartzJob" class="com.zxgs.task.QuartzJob" />
    
    <!-- 定时任务 -->
    <bean id="quartzTestTask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="quartzTest"></property>
        <property name="targetMethod" value="autoRun"></property>
        <property name="concurrent" value="true"></property>
    </bean>
    
    <bean id="quartzJobTask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="quartzJob"></property>
        <property name="targetMethod" value="work"></property>
        <property name="concurrent" value="true"></property>
    </bean>

    <!-- 定时任务触发器 -->
    <bean id="quartzTestTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="quartzTestTask"/>
        <!-- 每五秒 -->
        <property name="cronExpression" value="0/5 * * * * ?"></property>
    </bean>
    
     <bean id="quartzJobTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="quartzJobTask"/>
        <!-- 每二秒 -->
        <property name="cronExpression" value="0/2 * * * * ?"></property>
    </bean>

    <bean name="quartzScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref local="quartzTestTrigger" />
                <ref local="quartzJobTrigger" />
            </list>
        </property>
    </bean>

</beans>

二、通过注解实现

使用@Scheduled注解进行开发

1、在xml中添加空间名

xmlns:task="http://www.springframework.org/schema/task"

xsi中引入
http://www.springframework.org/schema/task/spring-task-3.0.xsd

2、扫描包 

 <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
	<context:component-scan base-package="com.zxgs.task" />
    <!--启用注解驱动，spring才能识别@Scheduled注解 -->
	<task:annotation-driven scheduler="taskScheduler" mode="proxy" />
	<!--配置定时任务线程池线程数量， 官方推荐pool-size：5-10 -->
	<task:scheduler id="taskScheduler" pool-size="10" />

3、 在类上加注解

	@Scheduled(cron="0/2 * * * * ?")
	public void work() {
		System.out.println("QuartzJob is time to run :" + new Date().toString());
	}
