spring配置定时器的两种方式quartz和TimerTask（示例转）

转自：http://blog.csdn.net/daryl715/article/details/1639876

首先我们编写调度服务,继承java.util.TimerTask

 

package TimerTest;

import java.util.Date;
import java.util.TimerTask;

public class TimerService extends TimerTask {    
    public void run() {
        System.out.println(new Date().getSeconds());        
    }
}

配置文件：以下是两种定时器的配置，使用任意一种即可

方式一： TimerTask定时器配置：

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd" >
<beans>
  <!-- 配置调度方法 -->
  <bean id="reportTask" class="TimerTest.TimerService"/>
  <!-- 配置定时器任务 -->
  <bean id="scheduledReportTask" class="org.springframework.scheduling.timer.ScheduledTimerTask">
    <property name="timerTask">
      <ref bean="reportTask"/>
    </property>
     <property name="period">
      <value>1000</value>
    </property>

  </bean>
  <!-- 启动定时器 -->
  <bean id="start" class="org.springframework.scheduling.timer.TimerFactoryBean">
    <property name="scheduledTimerTasks">
      <list>
      <ref bean="scheduledReportTask"/>
    </list>
    </property>
  </bean>
</beans>

方式二：Quartz定时器配置： 该定时器，需要导入quatz-all1.6.jar 和common-collections.jar包

<?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:p="http://www.springframework.org/schema/p"
    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-3.0.xsd
           http://www.springframework.org/schema/context 
           http://www.springframework.org/schema/context/spring-context-3.0.xsd
           http://www.springframework.org/schema/aop 
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
           http://www.springframework.org/schema/tx 
           http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"
           >
           
  <!-- 任务类 -->
 <bean id="myTask" class="myspring.mvc.web.TimerSerivce"/>
 
 <!-- 代理指定运行的任务方法  -->
 <bean id="myCron-over-timer" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
     <property name="targetObject">
         <ref bean="myTask"/>
     </property>
     <property name="targetMethod">
         <value>run</value>
     </property>
 </bean>
           
 <!-- 设置任务的运行周期 -->
<bean id="myCron-trigger-timer" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail">
              <ref bean="myCron-over-timer"/>
        </property>
        <property name="cronExpression">
            <value>*/1 * * * * ?</value>
        </property>
</bean>

<!-- 启动定时器 -->
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
            <property name="triggers">
                    <list>
                            <ref bean="myCron-trigger-timer"/>
                    </list>
            </property>
    </bean>


</beans>

 

 

测试代码：

 

package TimerTest;

import java.io.File;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;




public class TestTimer {

    public static void main(String[] args) {

        String filePath=System.getProperty("user.dir")+File.separator+"TimerTest"+File.separator+"hello.xml";
        
        ApplicationContext  context=new FileSystemXmlApplicationContext(filePath);
        
        //如果使用BeanFactory,则必须调用factory.getBean("start"),才能启动调度任务
        
        
　　　　//或者直接把项目布署到服务器，启动服务器，则可看到控制台会打印当前秒数

    }
}

 

运行结果：

2007-6-5 23:16:24 org.springframework.context.support.AbstractApplicationContext prepareRefresh
信息: Refreshing org.springframework.context.support.FileSystemXmlApplicationContext@109a4c: display name [org.springframework.context.support.FileSystemXmlApplicationContext@109a4c]; startup date [Tue Jun 05 23:16:24 CST 2007]; root of context hierarchy

可以看到，每隔一秒就打印当前时间的秒数
