java定时器问题：quartz-job.xml

最近在开发里需要做一个定时器的功能，即到了某一特定时间执行自己所写的方法：

1：配置quartz-job.xml

<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	                       http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
	                       http://www.springframework.org/schema/context 
	                       http://www.springframework.org/schema/context/spring-context-4.3.xsd">                
	
	<bean id="downVodJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject" ref="ftpmediaTask"/>
		<property name="targetMethod" value="downVod"/>
	</bean>
	
	<bean id="downVodJobTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
		<property name="jobDetail" ref="downVodJob"/>
		<property name="cronExpression" value="0 35 09 * * ?" />
	</bean>
	<bean id="redVodJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject" ref="ftpreadTask"/>
		<property name="targetMethod" value="redWriteVod"/>
	</bean>
	
	<bean id="redVodJobTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
		<property name="jobDetail" ref="redVodJob"/>
		<property name="cronExpression" value="0 02 10 * * ?" />
	</bean>
	<bean name="startQuertz" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
		 	<list>
				<ref bean="downVodJobTrigger" />
				<ref bean="redVodJobTrigger" />
			</list>
		</property>
	</bean>
</beans>

1):引用两个bean，一个下载的定时任务，一个读取的定时任务（不一定非两个，视业务而定）

<bean name="startQuertz" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
		 	<list>
				<ref bean="downVodJobTrigger" />
				<ref bean="redVodJobTrigger" />
			</list>
		</property>
	</bean>

2）：以配置读取的定时任务为例：ref指向为redVodJob的bean

第一个property:对应你写的类，第二个对应你的方法。

bean为cronExpression的value即为配置时间。0 02 10 代表10点02分0秒

<bean id="redVodJobTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
		<property name="jobDetail" ref="redVodJob"/>
		<property name="cronExpression" value="0 02 10 * * ?" />
	</bean>

<bean id="redVodJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject" ref="ftpreadTask"/>
		<property name="targetMethod" value="redWriteVod"/>
	</bean>

3):贴上自己写的方法要使用@service注解

@Service
public class FtpreadTask {
	
	@Resource
	private ContentDao contentDao;
	@Resource
	private PictureDao pictureDao;
	@Resource
	private MultirateDao multirateDao;
	
	//读取影视资源
	@SuppressWarnings({ "unused", "resource" })
	public  void checkOocpTxt(String files) throws IOException {
		
	}
	public  void  redWriteVod() {
		

        checkOocpTxt();

}}4：配置好的quartz.xml文件一定要在springmvc里面引入

<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	                       http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
	                       http://www.springframework.org/schema/context 
	                       http://www.springframework.org/schema/context/spring-context-4.3.xsd">

	<context:component-scan base-package="com.hzqy">
		<context:exclude-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
	</context:component-scan>
	<context:annotation-config />
		<import resource="quartz-job.xml" />
</beans>
