Spring+quartz实现任务调度的小例子

Spring+quartz实现任务调度的小例子

实现任务调度分为三大模块：1.任务调度器Scheduler;
2.触发器cronTrigger；
3.自定义任务JobtTask；

*自定义任务JobtTask*package com.zjt.quartz;import java.text.SimpleDateFormat;import java.util.Date;import org.quartz.Job;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;/** * 自定义任务; */public class MyJob implements Job {    // 自定义任务Task;    public void execute(JobExecutionContext context) throws JobExecutionException {        System.out.println("当前任务开始执行: " +         new SimpleDateFormat("yyyy-MM-dd HH-mm-ss")         .format(new Date()));    }}

*测试类*package com.zjt.quartz;import java.text.ParseException;import org.quartz.JobExecutionException;import org.springframework.context.support.ClassPathXmlApplicationContext;/** *  测试类 */public class Test {    @SuppressWarnings("resource")    public static void main(String[] args) throws ParseException, JobExecutionException {        System.out.println("--------------------------------");        new ClassPathXmlApplicationContext("applicationContext.xml");    }}
