Spring Boot集成Quartz快速入门Demo

1.Quartz介绍

  Quartz是OpenSymphony开源的一个项目,是一个由Java编写的开源作业调度框架。

特点

  1. 支持分布式高可用,我们需要某个定时任务在多个节点中只有某个节点可以执行时,就需要Quartz来实现,否则使用@Scheduled等方式会造成所有节点都执行一遍。
  2. 支持持久化,Quartz有专门的数据表来实现定时任务的持久化。
  3. 支持多任务调度和管理,Quartz可以在数据库中存储多个定时任务进行作业调度,可以实现定时任务的增删改查等管理。

组成

Quartz由三部分组成:
  1. 任务:JobDetail
  2. 触发器:Trigger(分为SimpleTrigger和CronTrigger)
  3. 调度器:Scheduler

2.mysql环境搭建

第一个mysql数据库

docker run --name docker-mysql -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 -d mysql

初始化数据


create database demo;
#
# Quartz seems to work best with the driver mm.mysql-2.0.7-bin.jar
#
# PLEASE consider using mysql with innodb tables to avoid locking issues
#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

job

打印出当前线程名、当前时间及当前调用次数
package com.et.quartz.job;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.concurrent.atomic.AtomicInteger;

//SimpleJob是一个简单定时任务体,用于打印出当前线程名、当前时间及当前调用次数
public class SimpleJob extends QuartzJobBean {

    private final static AtomicInteger counter = new AtomicInteger(1);

    @Override
    protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        LocalDateTime now = LocalDateTime.now();

}

Jobinit.java

job初始化,并将相关数据持久化都数据库
package com.et.quartz.config;

import com.et.quartz.job.SimpleJob;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.stereotype.Component;

import java.util.HashSet;
import java.util.Set;

@Component
public class JobInit implements ApplicationRunner {

    private static final String ID = "SUMMERDAY";

    @Autowired
    private Scheduler scheduler;

    @Override
    public void run(ApplicationArguments args) throws Exception {
        JobDetail jobDetail = JobBuilder.newJob(SimpleJob.class)
                .withIdentity(ID + " 02")
                .storeDurably()
                .build();
        CronScheduleBuilder scheduleBuilder =
                CronScheduleBuilder.cronSchedule("0/10 * * * * ? *");
        //create  task trigger
        Trigger trigger = TriggerBuilder.newTrigger()
                .forJob(jobDetail)
                .withIdentity(ID + " 02Trigger")
                .withSchedule(scheduleBuilder)
                .startNow() //exceute Now
                .build();
        Set<Trigger> set = new HashSet<>();
        set.add(trigger);
        // boolean replace it will replace quartz's task in database  when the task is started
        scheduler.scheduleJob(jobDetail, set, true);
    }
}

DemoApplication.java

package com.et.quartz;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

   public static void main(String[] args) {
      SpringApplication.run(DemoApplication.class, args);
   }
}

4.测试

启动Spring Boot应用,发现每10秒运行一次定时任务
Execute quartz "SimpleJob", threadName = "hyhScheduler_Worker-1", the 1th execution, time = "2024-04-23 09:14:23.031"
Execute quartz "SimpleJob", threadName = "hyhScheduler_Worker-2", the 2th execution, time = "2024-04-23 09:14:30.019"
Execute quartz "SimpleJob", threadName = "hyhScheduler_Worker-3", the 3th execution, time = "2024-04-23 09:14:40.015"
Execute quartz "SimpleJob", threadName = "hyhScheduler_Worker-4", the 4th execution, time = "2024-04-23 09:14:50.017"
Execute quartz "SimpleJob", threadName = "hyhScheduler_Worker-5", the 5th execution, time = "2024-04-23 09:15:00.022"
Execute quartz "SimpleJob", threadName = "hyhScheduler_Worker-6", the 6th execution, time = "2024-04-23 09:15:10.024"
查看是否数据库有任务信息
