1.新建一个定时器配置文件，这里叫spring-task.xml,内容如下：
<?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:mvc="http://www.springframework.org/schema/mvc" 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-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.1.xsd">
<bean id="midTask" class="com.afmobi.task.MidTask" />
<!--注册定时器类，后面讲 -->
<!--定时器1 begin-->
<bean id="midDownTaskInfo"
class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="midTask" />
<property name="targetMethod" value="midownloadItemTask" />
<!--指定定时器任务类要执行的方法名称 这里是midownloadItemTask -->
</bean>
<bean id="midDownTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<!--配置定时器任务的调度器 -->
<property name="jobDetail" ref="midDownTaskInfo" />
<property name="cronExpression" value="0 0 01 * * ?" />
<!--默认每日凌晨1点执行 -->
</bean>
<!--定时器2 begin-->
<bean id="midStatusTaskInfo"
class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="midTask" />
<property name="targetMethod" value="midownloadStatusTask" />
</bean>
<bean id="midStatusTaskTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="midStatusTaskInfo" />
<property name="cronExpression" value="0 10 01 * * ?" />
<!--每日凌晨1点10分执行-->
</bean>
<!--注册监听器 -->
<bean id="registerQuartz"
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<!--注册定时器实体 集合 -->
<property name="triggers">
<list>
<ref local="midDownTrigger" />
<ref local="midStatusTaskTrigger" />
</list>
</property>
</bean>
</beans>
2.在spring的主配置文件里引入此xml文件：
<import resource="spring-task.xml" /><!-- 定时器配置文件 -->
3.定时器实现类：(实现了2个定时器的方法)
public class MidTask {
@Autowired
private TaskService taskService;
/**
* 下载产品中间表 mid_download_item_yyyy_MM 定时任务
*/
private void midownloadItemTask() {
List list = taskService.downloadFinishList();
}
/**
*下载状态中间表 mid_date_download_status 定时任务
*/
private void midownloadStatusTask() {
List list = taskService.downloadStatusList();
}
}
到此结束，（至于缺少的jar包什么的这里不做说明，报错了，自己去网上下载相应的jar包就ok了。）
