scheduletask任务调度

1.导入jar包

2.创建entity、

package cn.happy.entity;

public class Plan {
    //时间
    private String date;
    //任务
    private String task;
    
    public Plan() {

    }

    public Plan(String date, String task) {
        this.date = date;
        this.task = task;
    }
  
    @Override
    public String toString() {
        return "Plan [date=" + date + ", task=" + task + "]";
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public String getTask() {
        return task;
    }

    public void setTask(String task) {
        this.task = task;
    }
}

3、创建service

package cn.happy.service;

import java.util.ArrayList;
import java.util.List;

import cn.happy.entity.Plan;

public class RemindService {
    
    
    public void print(String name){
        List<Plan> list = getPlan(name);
        System.out.println(name+"的提醒信息\n");
        for (Plan plan : list) {
            System.out.println(plan);
        }
    }
     public void printPlan(String userName){
           List<Plan> plansForToday = getPlansForToday(userName);
            System.out.print(userName + "的提醒信息：\n");
            for(Plan plan:plansForToday){
                System.out.print(plan +"\n");
            }
       }
       
       public List<Plan> getPlansForToday(String userName){
            //模拟数据库查询,仅为说明问题
            List<Plan> list = new ArrayList<Plan>();
            list.add(new Plan("2003-8-9 9:00","研讨会 | 地点：会议室C01"));
            list.add(new Plan("2003-8-9 14:00","汇报 | 地点：总裁办公室"));
            return list;
        }
       
       public List<Plan> getPlan(String name){
           List<Plan> list = new ArrayList<Plan>();
           list.add(new Plan("2016年12月18日10:59", "研讨会"));
           list.add(new Plan("2016-12-18 11:01","汇报"));
           return list;
       }
}

4、创建quartz

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

package cn.happy.quartz;   import org.quartz.Job; import org.quartz.JobExecutionContext; import org.quartz.JobExecutionException;   import cn.happy.service.RemindService; /**  * 工作调度类  quartz 类 需要实现 job接口  * @author SLEEP  *  */ public class RemindJob implements Job {     //注入service对象     RemindService service =new RemindService();     @Override     public void execute(JobExecutionContext arg0) throws JobExecutionException {         service.printPlan("见见");     }                     }

5.创建测试类（关键）

package cn.happy.test;

import java.util.Date;

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;

import cn.happy.quartz.RemindJob;
/**
 * 测试类
 * 使用quartz类
 * @author SLEEP
 *
 */
public class Test {
    
    public void doRemind() throws SchedulerException, InterruptedException {
    
        
        //创建一个任务    
        JobDetail  job= JobBuilder.newJob(RemindJob.class)  //
                         .withIdentity("job1", "group1")
                         .build();    
        //创建一个触发器
         Trigger trigger = TriggerBuilder.newTrigger() 
                 .withIdentity("myTrigger", "myTriggerGroup")
                 .withSchedule(SimpleScheduleBuilder.simpleSchedule()
                     .withIntervalInSeconds(5)
                     .repeatForever())
                 .startAt(new Date(System.currentTimeMillis() + 1000))
                 .build();
         //创建调度工厂
         SchedulerFactory stdSchedulerFactory = new StdSchedulerFactory();
         //创建一个调度者
         Scheduler scheduler = stdSchedulerFactory.getScheduler();
         //注册并进行调度
         scheduler.scheduleJob(job,trigger);
         //启动调度
         scheduler.start();
        //创建调度者工厂
        SchedulerFactory sfc = new StdSchedulerFactory();
        //创建一个调度者
        Scheduler sched = sfc.getScheduler();
        //注册并进行调度
        sched.scheduleJob(job, trigger);
        //启动调度
        sched.start();
        /*//sleep10s
        Thread.sleep(10000);
        //关闭调度
        sched.shutdown();*/
    }
    
    /**
     * 
     */
    public static void main(String[] args) {
        try{
            Test testJob = new Test();
            testJob.doRemind();
        }catch(Exception e){
            e.printStackTrace();
        }
    }
}
