java quartz framework timing tasks

1. Import the package

pom.xml

<!--quartz-->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.2.1</version>
        </dependency>
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>
            <version>2.2.1</version>
        </dependency>

2. Executive body

package com.example.demo.Quartz;

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

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

/**
 * Task execution class
 */
public class QuartzJob implements Job {

    @Override
    public void execute(JobExecutionContext content) throws JobExecutionException {
        System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
        JobDataMap dataMap = content.getJobDetail (). GetJobDataMap ();
        String param = dataMap.getString("param");
        System.out.println("The parameter passed is ="+param );
    }
}

3. Create tasks

package com.example.demo.Quartz;

import org.quartz.*;
import org.quartz.impl.StdSchedulerFactory;

public class QuartzManager {
    //create scheduler
    public static Scheduler getScheduler() throws SchedulerException {
        SchedulerFactory schedulerFactory = new StdSchedulerFactory();
        return schedulerFactory.getScheduler();
    }


    public static void schedulerJob() throws SchedulerException{
        //create task
        JobDetail jobDetail = JobBuilder.newJob(QuartzJob.class).withIdentity("job1", "group1").build();
        jobDetail.getJobDataMap().put("param","ooo");
        //Create trigger to execute every 3 seconds
        Trigger trigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "group3")
                .withSchedule(SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(3).repeatForever())
                .build();
        Scheduler scheduler = getScheduler();
        // put the task and its trigger into the scheduler
        scheduler.scheduleJob(jobDetail, trigger);
        //The scheduler starts scheduling tasks
        scheduler.start();

    }

    public static void main(String[] args) throws SchedulerException {
        QuartzManager mainScheduler = new QuartzManager();
        mainScheduler.schedulerJob();
    }

}
