需要定時執行一些計劃（定時更新等），這樣的計劃稱之為計劃任務

Spring抽象封裝了java提供的Timer與TimerTask類

也可以使用擁有更多任務計劃功能的Quartz

實現類

package com.pb.task.timertask;import java.util.Iterator;import java.util.List;import java.util.TimerTask;public class BatchUpdate extends TimerTask {    //存放SQL    private List commons;    @Override    public void run() {        //輸出語句        for(Iterator it=commons.iterator();it.hasNext();){            System.out.println(it.next());        }        System.out.println("timertask批量更新完畢");    }    public void setCommons(List commons) {        this.commons = commons;    }        }

配置文件：

<?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:p="http://www.springframework.org/schema/p"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd"><bean id="batch_update" class="com.pb.task.timertask.BatchUpdate"><property name="commons"><list><value>update personn set onduty="出勤" where date=${ontime}</value><value>update personn set onduty="缺勤" where date=${miss}</value><value>update personn set onduty="遲到" where date=${late}</value><value>update personn set onduty="早退" where date=${early}</value></list></property></bean><!-- 配置任務調度的類 --><bean id="update_schuleTask" class="org.springframework.scheduling.timer.ScheduledTimerTask"><property name="timerTask" ref="batch_update"/><!--啟動任務后多久開始執行  --><property name="delay"><value>1000</value></property><!--第一次記動后后多久執行一次  2秒重復一次--><property name="period"><value>2000</value></property></bean><!--啟動任務  --><bean id="timerFactory" class="org.springframework.scheduling.timer.TimerFactoryBean"><!--任務調度類  --><property name="scheduledTimerTasks"><list><ref local="update_schuleTask"/></list></property></bean></beans>

測試類只需要調用

applicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");

package com.pb.task.timertask;import java.util.Iterator;import java.util.List;import java.util.TimerTask;public class MethodInvokingBatchUpdate {    //存放SQL    private List commons;        public void run() {        //輸出語句        for(Iterator it=commons.iterator();it.hasNext();){            System.out.println(it.next());        }        System.out.println("MethodInvoking批量更新完畢");    }    public void setCommons(List commons) {        this.commons = commons;    }        }

傳統QuartzJob

需要jta.jar 和quartz-all-1.6.0.jar2個jar包

package com.pb.quartz.job;import java.util.Date;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;import org.springframework.scheduling.quartz.QuartzJobBean;/** * 傳統的使用Quartz * */public  class QuartzUpdate extends QuartzJobBean {    private String command;        @Override    protected void executeInternal(JobExecutionContext context)            throws JobExecutionException {        System.out.println(new Date()+":"+"傳統Quartz任務被高度");        for (int i = 1; i <= 10; i++) {            System.out.println("命令："+command+"第"+i+"次被讞用");                    }        System.out.println(new Date()+"傳統Quartz調度完成");    }    public void setCommand(String command) {        this.command = command;    }    }

使用MethodInvoking方式

package com.pb.quartz.methodinvoking.update;public class UpdateQuartzJob {        private String command;        public void show(){        System.out.println("MethodInvoking方式調度開始"+command);        for (int i = 1; i <=10; i++) {            System.out.println("命令："+command+"第"+i+"次調用");        }        System.out.println("MethodInvoking方式調度結束"+command);    }    public String getCommand() {        return command;    }    public void setCommand(String command) {        this.command = command;    }    }
