<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">1. 需要的lib: 前两个是spring必备的包，后三个是定时任务需要的包</span>

spring.jar

spring-sources.jar

commons-collections-3.1.jar

jta.jar

quartz-all-1.6.0.jar

2. applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"><beans>    <bean name="timingTask" class="com.ctrip.bi.uss.service.TimingTask" />    <bean id="methodInvokingJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">       <property name="targetObject">           <ref bean="timingTask" />       </property>       <property name="targetMethod">           <value>LoadData</value>       </property>    </bean>    <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">       <property name="jobDetail">           <ref bean="methodInvokingJobDetail" />       </property>       <span style="white-space:pre"></span><!-- 每隔1分钟调度一次 -->       <property name="cronExpression">           <value>0 0/1 * * * ?</value>         </property>    </bean>    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">       <property name="triggers">           <list>              <ref local="cronTrigger" />           </list>       </property>    </bean></beans>

3. 定时任务类TimingTask

<pre name="code" class="plain">package com.ctrip.bi.uss.service;import org.apache.log4j.Logger;import com.ctrip.bi.uss.dao.LoadDataDao;public class TimingTask {public static Logger log = Logger.getLogger(TimingTask.class);CheckFileVersion cfv = new CheckFileVersion();long cVersion = 1407310670846L;long localVersion = 0;String path = "D:\\Data";public void LoadData() {LoadDataDao loadDataImpl = new LoadDataDao();try {log.info("Start task>........");// 查看目录下文件的版本localVersion = cfv.GetFileVersion(path);if (cVersion < localVersion) {// 定时导入数据loadDataImpl.loadToBdb(false);} else {log.info("Current version is the newest one. No need to update!");}System.out.println("Time:" + new java.util.Date().toLocaleString()+ "]----->Loading value...");log.info("End task!");} catch (Exception e) {log.error( e.getCause()+e.getMessage());}}}

4. 测试的类 TestTimingTask

package com.ctrip.bi.uss.test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class TestTimingTask {public static void main(String[] args) {System.out.println("Loading spring configuaration file....");ApplicationContext context = new ClassPathXmlApplicationContext("/applicationContext.xml");System.out.println("Finish loading file!");}}
