Quartz使用-入门使用(java定时任务实现)

注：这里使用的是Quartz1.6.5版本(包：quartz-1.6.5.jar)

[java] view
plaincopy

//测试main函数

//QuartzTest.java

package quartzPackage;

import java.text.SimpleDateFormat;

import java.util.Date;

public class QuartzTest {

/** *//**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

SimpleDateFormat DateFormat = new SimpleDateFormat("yyyyMMddHHmmss");

Date d = new Date();

String returnstr = DateFormat.format(d);

TestJob job = new TestJob();

String job_name ="11";

try {

System.out.println(returnstr+ "【系统启动】");

QuartzManager.addJob(job_name,job,"0/2 * * * * ?"); //每2秒钟执行一次

// Thread.sleep(10000);

// System.out.println("【修改时间】");

// QuartzManager.modifyJobTime(job_name,"0/10 * * * * ?");

// Thread.sleep(20000);

// System.out.println("【移除定时】");

// QuartzManager.removeJob(job_name);

// Thread.sleep(10000);

//

// System.out.println("/n【添加定时任务】");

// QuartzManager.addJob(job_name,job,"0/5 * * * * ?");

} catch (Exception e) {

e.printStackTrace();

}

}

}

//测试工作类

//TestJob.java

package quartzPackage;
