TaskManager

package mytest.task;

import java.text.ParseException;

import org.quartz.CronTrigger;
import org.quartz.Job;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.impl.StdSchedulerFactory;

	public static <T extends Job> void insertTask(String jobName,String expression,Class<T> jobCalss){
		try {

			CronTrigger cronTrigger = new CronTrigger(jobName, Scheduler.DEFAULT_GROUP,expression);
			JobDetail jobDetail  = new JobDetail(jobName,Scheduler.DEFAULT_GROUP,jobCalss);

			schedule.start();
		} catch (SchedulerException e) {
			e.printStackTrace();
		} catch (ParseException e) {

BastTask

package mytest.task;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;/**
 * @author luke Lin
 * @version 1.0.0 2017年8月9日 上午9:40:43
 */
public abstract class BastTask implements Job{

	private static int taskCount = 0;
	
	public static <T extends Job> void init(String jobName,String expression,Class<T> jobCalss){
		TaskManager.insertTask(jobName, expression, jobCalss);
	}
	
	public void execute(JobExecutionContext context) throws JobExecutionException {
		long startTime = System.currentTimeMillis();
		int currentCount = taskCount++;
		System.out.println(context.getJobDetail().getFullName() + "-" + currentCount + " 定时任务开始执行");
		new Thread(new Runnable() {
			public void run() {
				doTask();
			}
		}).start();
		long endTime = System.currentTimeMillis();
		System.out.println(context.getJobDetail().getFullName() + "-" + currentCount + " 定时任务执行完成,耗时:" + (endTime - startTime) + "毫秒");
	}
	
	public abstract void doTask();

}


编码自己任务类

package mytest.task.choice;

import java.util.concurrent.LinkedBlockingQueue;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;

import mytest.task.BastTask;

/**
 * 
 * 
 * @author luke Lin
 * @version 1.0.0 2017年8月9日 上午9:50:47
 */
public class DefaultTask extends BastTask{

	private ThreadPoolExecutor cancelPoolExecutor = new ThreadPoolExecutor(10, 100, 0L, TimeUnit.SECONDS,new LinkedBlockingQueue<Runnable>()); 

	@Override
	public void doTask() {
		//定时任务自己的任务业务
		System.out.println("我要执行我的任务了!");
		
		for(int i=0;i<10;i++){
			cancelPoolExecutor.submit(new CancelOrderRunnable());
			System.out.println("[cancelPoolExecutor] : " + cancelPoolExecutor.toString());
		}
	}
	
	public static void main(String[] args) {
		DefaultTask.init("DefaultTask", "0/1 * * * * ?", DefaultTask.class);
	}
	
	/**
	 * 线程取消
	 * @author Jews
	 */
	public class CancelOrderRunnable implements Runnable {

		public void run() {
			System.out.println("这里是我的业务逻辑");
			try {
				throw new Exception();
			} catch (Exception e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
		
	}
