Spring定时器的使用

转自：http://cuisuqiang.iteye.com/blog/1320255

1.首先要增加相应的JAR。
因为这是一个小例子，使用的JAR包不是很多，用到了spring.jar，quartz-all-1.6.5.jar，quartz-1.5.2.jar，commons-logging.jar，log4j-1.2.14.jar！不用关心版本，从你下载到的Spring中找即可。

2.定义web.xml配置文件
要在配置文件中定义Spring和Log4j的使用。具体看工程即可。重点关注的是如果你做例子时使用了web-app_2_5.xsd，那么在部分服务器上是跑不起来的

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

3.spring配制文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref local="BusinessTestTrigger"/>
</list>
</property>
</bean>
<bean id="BusinessTestTime" class="com.Test">
<property name="para" value="Spring定时测试v1"></property>
</bean>
<bean id="BusinessTestDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject">
<ref bean="BusinessTestTime"/>
</property>
<property name="concurrent" value="false"></property>
<property name="targetMethod" value="run"></property>
</bean>

<bean id="BusinessTestTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail">
<ref bean="BusinessTestDetail"/>
</property>
<property name="cronExpression">
<value>0/5 * * * * ?</value>
</property>
</bean>
</beans>

4.java代码：

package com;

import java.text.SimpleDateFormat;
import java.util.Date;

public class Test{
private String para;
public void run(){
SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println("the para is "+para+" !Time is :"+format.format(new Date()));
}
public String getPara() {
return para;
}
public void setPara(String para) {
this.para = para;
}

}

5.结果如下图所示：
