spring 第11天 quartz任务调度_quartz框架信号倒计时-CSDN博客

本文链接：https://blog.csdn.net/luobing_csdn/article/details/66969914

Quartz是一个强大的企业级任务调度框架，Spring中继承并简化了Quartz


首先说 jar的问题
从Spring3.2.4才开始支持quartz-2.x

如果版本低于 3.2.4 需要导入 quartz-1.x,commons-collections-3.1.jar,jboss-transaction-api_1.1_spec-1.0.0.Final.jar(javax.transaction.UserTransaction.class)

//在java使用quartz


package quartz;

import java.util.Date;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

/**
 * 定义quartz作业类
 * 单独 使用quartz
 *
 */
public class BuzJob implements Job {
	private boolean isRunning=false;
	
	@Override
	public void execute(JobExecutionContext arg0) throws JobExecutionException {
		// TODO Auto-generated method stub
		if(!isRunning){
			System.out.println(new Date()+" 作业被调度.");
			for (int s = 0; s < 100; s++) {
				System.out.println("作业完成"+(s+1)+"%");
				try {
					Thread.sleep(1000);
					
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
			System.out.println(new Date()+" 作业调度结束.");
		}else{
			System.out.println(new Date()+" 任务退出");
		}
	}

}

//test
package quartz;

import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SimpleTrigger;
import org.quartz.Trigger;
import org.quartz.impl.StdSchedulerFactory;

/**
 * 使用quartz的调度器
 * @author Bin
 *
 */
public class MyQuartzService {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		try {
			startScheduler();
		} catch (SchedulerException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	
	public static void startScheduler() throws SchedulerException{
		Scheduler sch=StdSchedulerFactory.getDefaultScheduler();
		
		JobDetail d=new JobDetail("buz", Scheduler.DEFAULT_GROUP, BuzJob.class);
		//重复调度2次,间隔 60s
		Trigger t=new SimpleTrigger("buz", Scheduler.DEFAULT_GROUP, 2, 60000);
		sch.scheduleJob(d, t);
		sch.start();
	}

}

//在spring中使用quartz
//使用MethodInvokingJobDetailFactoryBean 可以装配任何普通的bean中方法不用继承


package quartz;

public class QuartzJob {

	public void work(){
		System.out.println("Quartz调度");
	}
}

 <!-- step:1 定义 quartz业务类-->
 <!--定义一个  工作业务类,要做的事情-->
 <bean id="quartzjob" class="quartz.QuartzJob"/>

<!-- step:2  对业务类进行详情描述-->
   <!--采用  MethodInvokingJobDetailFactoryBean 装配 任务详情 -->

//使用JobDetailBean装配业务

	}

	@Override

			throws JobExecutionException {
		// TODO Auto-generated method stub
		if(!isRunning){
			System.out.println("开始工作");
			dog.sound();
			isRunning=false;

	}

}

   <!--step:3 对已经详情描述过的bean,装配给 触发器 -->
