Quartz任务调度示例

导入maven依赖

     <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.3.2</version>
     </dependency>

实现Job接口，实现 void execute(JobExecutionContext context)方法

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.stereotype.Component;
public class MyJob implements Job {
    private  static int num;
    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println(num++);
    }
}

创建执行器

package com.hand.service.job;
import com.hand.service.MyJob;
import org.quartz.*;
import org.quartz.impl.StdSchedulerFactory;
import java.util.concurrent.TimeUnit;

public class Test {
    public static void main(String[] args) throws Exception {
        // 1、创建调度器Scheduler
        SchedulerFactory schedulerFactory = new StdSchedulerFactory();
        Scheduler scheduler = schedulerFactory.getScheduler();

        // 2、创建JobDetail实例，并与MyJob类绑定(Job执行内容)
        JobDetail jobDetail = JobBuilder
                                .newJob(MyJob.class)
                                .withIdentity("job1", "group1")
                                .build();

        // 3、构建Trigger实例,每隔1s执行一次
        Trigger trigger = TriggerBuilder.newTrigger()
                .withIdentity("trigger1", "triggerGroup1")
                .startNow()//立即生效
                .withSchedule(SimpleScheduleBuilder
                                .simpleSchedule()
                                    //每隔1s执行一次
                                .withIntervalInSeconds(1)
                                    //循环执行
                                .repeatForever())
                .build();

        //4、执行
        scheduler.scheduleJob(jobDetail, trigger);
        System.out.println("--------任务调度开始执行 ! ------------");
        scheduler.start();

        //任务调度一直执行，执行时间为2分钟，之后停止执行任务调度
        TimeUnit.MINUTES.sleep(2);
        scheduler.shutdown();
        System.out.println("--------任务调度执行结束 ! ------------");

    }
}
