前提条件

<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.2</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>4.1.3.RELEASE</version>
</dependency>

使用方法分为MethodInvokingJobDetailFactoryBean方式和JobDetailBean方式,推荐使用第一种：完整项目下载
第一种方法：MethodInvokingJobDetailFactoryBean
第一步：编写一个普通的java类,类中随便写几个方法

package com.quartz.component;

import org.springframework.beans.factory.annotation.Autowired;

import com.quartz.Student;
import com.quartz.mapper.StudentMapper;

public class QuartzAutoTask {

@Autowired
private StudentMapper studentMapper;

public void eat(){
System.out.println("5秒吃饭");
}

public void sleep(){
int insert = studentMapper.insert(new Student(null, "张三", 18, "男"));
System.out.println(insert);
}
}

第二步：applicationContext-quartz.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> 
<!--作业的具体实现    -->
<bean id="autoTask" class="com.quartz.component.QuartzAutoTask" />

<!-- task -->
<!-- 定义了一个任务JobDetail -->
<bean id="quartzEat" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<!-- 指定要执行的类 -->
<property name="targetObject" ref="autoTask" />
<!-- 指定执行的方法 -->
<property name="targetMethod" value="eat" />
</bean>

<bean id="quartzSleep" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<!-- 指定要执行的类 -->
<property name="targetObject" ref="autoTask" />
<!-- 指定执行的方法 -->
<property name="targetMethod" value="sleep" />
</bean>

<!-- 调度定时任务 的触发器-->
<!-- 这种配置可以精确几点执行定时任务 -->
<bean id="cronQuartzEat" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail">
<ref bean="quartzEat"></ref>
</property>
<property name="cronExpression">
<!--每隔5秒触发一次  -->
<value>*/5 * * * * ?</value>
</property>
</bean>

<bean id="cronQuartzSleep" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail">
<ref bean="quartzSleep"></ref>
</property>
<property name="cronExpression">
<!--每隔10秒触发一次  -->
<value>*/10 * * * * ?</value>
</property>
</bean>

<!--启动定时任务的调度器,注意这里的ref bean -->
<bean id="schedulerFactoryBean" lazy-init="false" autowire="no"
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="cronQuartzEat"></ref>
<ref bean="cronQuartzSleep"></ref>
</list>
</property>
</bean>
</beans>

第三步：在web.xml中添加扫描applicationContext-quartz.xml

<!-- 加载spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

第二种方法：JobDetailBean方式
第一步：编写一个普通的java类继承QuartzJobBean

package com.quartz.component;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;

import com.quartz.Student;
import com.quartz.mapper.StudentMapper;

public class QuartzDetail extends QuartzJobBean {

@Override
protected void executeInternal(JobExecutionContext context)
throws JobExecutionException {
System.out.println("开始执行。。。");
//无法使用注解注入Bean,所以在配置文件中注入spring上下文,然后使用JobExecutionContext获得
ApplicationContext applicationContext = (ApplicationContext)context.getJobDetail().getJobDataMap().get("applicationContext");
StudentMapper studentMapper= (StudentMapper) applicationContext.getBean("studentMapper");
int insert = studentMapper.insert(new Student(null, "李四", 20, "男"));
System.out.println(insert);
}

}

第二步：applicationContext-quartz.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> 
<!-- 定义JobDetail的Bean -->
<bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
<!-- 指定任务Bean的实现类 -->
<property name="jobClass" value="com.quartz.component.QuartzDetail"/>
<!-- 指定job的名称 -->
<property name="name" value="myJob"/>
<!-- 指定job的分组 -->
<property name="group" value="jobs"/>
<!-- 必须设置为true,如果为false 当没有活动的触发器与之关联时会在调度器中删除该任务 -->
<property name="durability" value="true"/>
<!-- 测试是无法注入spring的Bean 所以注入spring上下文 -->
<property name="applicationContextJobDataKey" value="applicationContext"/>
</bean>

<!-- 定义触发器的Bean -->
<bean id="quartzDetail" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<!-- 指定jobDetail -->
<property name="jobDetail" ref="jobDetail"/>
<!-- 指定Cron表达式：每10秒执行一次 -->
<property name="cronExpression" value="*/10 * * * * ?"/>
</bean>
<!-- 执行实际的调度器-->
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="quartzDetail"/>
</list>
</property>
</bean>

</beans>

第三步：在web.xml中添加扫描applicationContext-quartz.xml

<!-- 加载spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

Spring轮询的配置使用
第一步：写一个类,给Spring管理,类上标注@Service

package com.quartz.service;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;

@Service
public class StudentServiceImpl {

@Scheduled(cron="*/1 * * * * ?")
public void execute(){
System.out.println("执行了。。。。。。");
}
}

第二步：在spring.xml上添加头信息

<?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:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.1.xsd">[/code]第三步：在spring.xml中添加以下注解 
<!-- 任务发送  -->
<task:annotation-driven />
