本文介绍了如何在SpringBoot项目中集成Quartz框架，用于实现定时任务。包括了pom.xml的配置，定义printWorkJob，设置简单触发器SimpleTrigger和计时触发器crontrigger，以及使用在线工具进行cron表达式配置，并提供了测试相关的说明。

SpringBoot整合定时任务框架Quartz

工程配置

工程配置

pom.xml

        <!-- https://mvnrepository.com/artifact/org.quartz-scheduler/quartz -->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.3.2</version>
        </dependency>

printWorkJob

package zhw.example.zhw.quartz;

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

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

public class printWorkJob implements Job {
    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        String printTime = new SimpleDateFormat("yy-MM-dd HH-mm-ss").format(new Date());
        System.out.println("PrintWordsJob start at:" + printTime + ", prints: Hello Job-" + new Random().nextInt(100));
    }
}

简单触发器SimpleTrigger

package zhw.example.zhw.quartz;

import org.quartz.*;
import org.quartz.impl.StdSchedulerFactory;
import org.springframework.stereotype.Component;

import java.util.Date;
import java.util.concurrent.TimeUnit;
@Component
public class printScheduler {

    public printScheduler() throws SchedulerException, InterruptedException {
        // 1、创建调度器Scheduler
        SchedulerFactory schedulerFactory = new StdSchedulerFactory();
        Scheduler scheduler = schedulerFactory.getScheduler();
        // 2、创建JobDetail实例，并与printWorkJob类绑定(Job执行内容)
        JobDetail jobDetail = JobBuilder.newJob(printWorkJob.class)
                .withIdentity("job1", "group1").build();

        Date startDate = new Date();
        startDate.setTime(startDate.getTime()+5000);
        Date endData = new Date();
        endData.setTime(startDate.getTime()+5000);

        // 3、构建Trigger实例,每隔1s执行一次
        SimpleTrigger  trigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "triggerGroup1")
                .startNow()//立即生效
                .startAt(startDate)
                .endAt(endData)
                .withSchedule(SimpleScheduleBuilder.simpleSchedule()
                        .withIntervalInSeconds(1)//每隔1s执行一次
                        .repeatForever()).build();//一直执行

        //4、执行
        scheduler.scheduleJob(jobDetail, trigger);
        System.out.println("--------scheduler start ! ------------");
        scheduler.start();
    }
}

计时触发器crontrigger

package zhw.example.zhw.quartz;

import org.quartz.*;
import org.quartz.impl.StdSchedulerFactory;
import org.springframework.stereotype.Component;

import java.util.Date;
import java.util.concurrent.TimeUnit;
@Component
public class printScheduler {

    public printScheduler() throws SchedulerException, InterruptedException {
        // 1、创建调度器Scheduler
        SchedulerFactory schedulerFactory = new StdSchedulerFactory();
        Scheduler scheduler = schedulerFactory.getScheduler();
        // 2、创建JobDetail实例，并与printWorkJob类绑定(Job执行内容)
        JobDetail jobDetail = JobBuilder.newJob(printWorkJob.class)
                .withIdentity("job1", "group1").build();

        // 3、构建Trigger实例,每隔1s执行一次
        CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "triggerGroup1")
                .startNow()//立即生效
                .withSchedule(CronScheduleBuilder.cronSchedule("0 34 * * * ? *"))
                .build();

        //4、执行
        scheduler.scheduleJob(jobDetail, trigger);
        System.out.println("--------scheduler start ! ------------");
        scheduler.start();
    }
}
