Quartz 的实现

Quartz  maven jar包

<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.3.0</version>
</dependency>

 

job实现类

package com.llf.quartz;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.quartz.DisallowConcurrentExecution;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
@DisallowConcurrentExecution
public class hellojob implements Job {

    @Override
    public void execute(JobExecutionContext arg0) throws JobExecutionException {
        Date date=new Date();
        SimpleDateFormat ff=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        System.out.println("时间! "+ff.format(date));
        System.out.println("Hello Word!");
        int b=1/0;
    }

}
 

 main函数  多个job任务

package com.llf.quartz;

import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.SimpleScheduleBuilder;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdSchedulerFactory;

public class helloScheduler {

    public static void main(String[] args) throws SchedulerException {
      //创建一个JobDetai实例
     JobDetail jobDetail=JobBuilder.newJob(hellojob.class).withIdentity("myjob", "group").build();
        
     Trigger trigger= TriggerBuilder
                         .newTrigger()
                         .withIdentity("mytrigger", "group")
                         .startNow()
                         .withSchedule(
                         SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(2).repeatForever()).build();         
            
     //创建一个JobDetai实例
     JobDetail jobDetail1=JobBuilder.newJob(hellojob.class).withIdentity("myjob1", "group").build();
        
     Trigger trigger1= TriggerBuilder
                         .newTrigger()
                         .withIdentity("mytrigger1", "group")
                         .startNow()
                         .withSchedule(
                         SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(2).repeatForever()).build();         
            
     
     
     
     
       SchedulerFactory sfact=new StdSchedulerFactory();
       Scheduler scheduler=sfact.getScheduler();
       scheduler.start();
       scheduler.scheduleJob(jobDetail,trigger);
       scheduler.scheduleJob(jobDetail1,trigger1);
    }
