spring实现定时器

最近开发项目需要用到定时器，于是研究了一下，下面就是具体的配置过程
1.新建一个java类，命名为TaskquartzController.class，创建一个方法，名为deleteOrder。注意配置文件中的几个id
[code lang="java"]
public class TaskquartzController {
/**
* 定时器
*
* @see
* @since 1.0
*/
public void deleteOrder(){
System.out.println("定时器测试");
}

}
[/code]
2.新建一个xml文件，命名为interf-task.xml
里面的内容为
[code lang="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">

<!-- 实例化bean -->
<bean id= "deleteOrderQuartz" class ="com.zhinianblog.taskquartz.controller.TaskquartzController"/>

<!-- 配置MethodInvokingJobDetailFactoryBean -->
<bean id= "deleteOrderMethod" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="deleteOrderQuartz"/>
<property name="targetMethod" value="deleteOrder"/>
<property name="concurrent" value="false"/>
</bean>

<!-- 配置定时表达式 -->
<bean id= "deleteOrderTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean" >
<property name="jobDetail" ref="deleteOrderMethod" />
<!-- 每5秒执行一次 -->
<!-- /代表每隔 -->
<!-- 秒 分 时 天 月 ? 年 -->
<property name="cronExpression" value="0/5 * * * * ?" />
</bean>

<!-- 配置调度工厂 -->
<bean id= "testSchedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers" >
<list>
<ref bean="deleteOrderTrigger" />
</list>
</property>
</bean>
</beans>
[/code]
3.在ApplicationContext.xml文件中引入该定时器文件
[code lang="xml"]
<!-- 配置定时任务 -->
<import resource="interf-task.xml"/>
[/code]
4.启动项目，就会看到控制台每5秒输出信息
