quartz的简单实现
1.方式一Java代码方式
需要quartz-1.8.0.jar, 核心代码实现如下：
package com.ibm.scheduler;
import java.util.Date;
import org.quartz.Job;
import org.quartz.JobDetail;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.quartz.Trigger;
import org.quartz.helpers.TriggerUtils;
public class QuartzTest implements Job {
@Override
//该方法实现需要执行的任务
public void execute(JobExecutionContext arg0) throws JobExecutionException {
System.out.println("Generating report - "
+ arg0.getJobDetail().getFullName() + ", type ="
+ arg0.getJobDetail().getJobDataMap().get("type"));
System.out.println(new Date().toString());
}
public static void main(String[] args) {
try {
// 创建一个Scheduler
SchedulerFactory schedFact =
new org.quartz.impl.StdSchedulerFactory();
Scheduler sched = schedFact.getScheduler();
sched.start();
// 创建一个JobDetail，指明name，groupname，以及具体的Job类名，
//该Job负责定义需要执行任务
JobDetail jobDetail = new JobDetail("myJob", "myJobGroup",
QuartzTest.class);
jobDetail.getJobDataMap().put("type", "FULL");
// 创建一个每周触发的Trigger，指明星期几几点几分执行
Trigger trigger = TriggerUtils.makeWeeklyTrigger(3, 16, 38);
trigger.setGroup("myTriggerGroup");
// 从当前时间的下一秒开始执行
trigger.setStartTime(TriggerUtils.getEvenSecondDate(new Date()));
// 指明trigger的name
trigger.setName("myTrigger");
// 用scheduler将JobDetail与Trigger关联在一起，开始调度任务
sched.scheduleJob(jobDetail, trigger);
} catch (Exception e) {
e.printStackTrace();
}
}
}
/**
输出结果:
Generating report - myJobGroup.myJob, type =FULL
Tue Feb 8 16:38:00 CST 2011
Generating report - myJobGroup.myJob, type =FUL
Tue Feb 15 16:38:00 CST 2011
*/
2.方式二Spring整合方式
需要spring的jar包和quartz-1.8.0.jar, 核心代码配置实现如下：
<?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:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd" default-lazy-init="false"> <!-- 订单状态自动更新 --> <bean id="initOrderStatusTaskTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail"> <bean class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <property name="targetObject"> <ref bean="OrderQuartzService" /> </property> <property name="targetMethod"> <value>init</value> </property> </bean> </property> <property name="cronExpression"> <value>0 0 1 * * ?</value> </property> </bean> <!-- 加入任务 --> <bean id="schedulerFactory" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref local="initOrderStatusTaskTrigger"/> </list> </property> </bean> </beans>
备注：OrderQuartzService是普通java接口，init为方法。
3.方式三 Java界面方式管理
主要文件分布
(1)TaskService.java
(2)TaskServiceImpl.java
(3)MyJob.java
(4)MyTask.java
(5)spring-task-schedule.xml
(6)界面管理JSP页面lvTaskQuartz_list.jsp,lvTaskQuartz_add.jsplvTaskQuartz_edit.jsp
