SpringBoot定时任务 - 集成quartz实现定时任务(单实例和分布式两种方式)

·  阅读 1483

最为常用定时任务框架是Quartz,并且Spring也集成了Quartz的框架,Quartz不仅支持单实例方式还支持分布式方式。本文主要介绍Quartz,基础的Quartz的集成案例本,以及实现基于数据库的分布式任务管理和控制job生命周期。@pdai

准备知识点

需要了解常用的Quartz框架。

什么是Quartz

来源百度百科, 官网地址:www.quartz-scheduler.org/

Quartz是OpenSymphony开源组织在Job scheduling领域又一个开源项目,它可以与J2EE与J2SE应用程序相结合也可以单独使用。Quartz可以用来创建简单或为运行十个,百个,甚至是好几万个Jobs这样复杂的程序。Jobs可以做成标准的Java组件或 EJBs。

它的特点如下

  • 纯java实现,可以作为独立的应用程序,也可以嵌入在另一个独立式应用程序运行
  • 强大的调度功能,Spring默认的调度框架,灵活可配置;
  • 作业持久化,调度环境持久化机制,可以保存并恢复调度现场。系统关闭数据不会丢失;灵活的应用方式,可以任意定义触发器的调度时间表,支持任务和调度各种组合,组件式监听器、各种插件、线程池等功能,多种存储方式等;
  • 分布式和集群能力,可以被实例化,一个Quartz集群中的每个节点作为一个独立的Quartz使用,通过相同的数据库表来感知到另一个Quartz应用

Quartz的体系结构

  • Job 表示一个工作,要执行的具体内容。
  • JobDetail 表示一个具体的可执行的调度程序,Job 是这个可执行程调度程序所要执行的内容,另外 JobDetail 还包含了这个任务调度的方案和策略。
  • Trigger 代表一个调度参数的配置,什么时候去调。
  • Scheduler 代表一个调度容器,一个调度容器中可以注册多个 JobDetail 和 Trigger。当 Trigger 与 JobDetail 组合,就可以被 Scheduler 容器调度了。

注: 上图来源于www.cnblogs.com/jijm123/p/1…

什么是Quartz持久化

  • 为什么要持久化

当程序突然被中断时,如断电,内存超出时,很有可能造成任务的丢失。 可以将调度信息存储到数据库里面,进行持久化,当程序被中断后,再次启动,仍然会保留中断之前的数据,继续执行,而并不是重新开始。

  • Quartz提供了两种持久化方式

Quartz提供两种基本作业存储类型:

  1. RAMJobStore

在默认情况下Quartz将任务调度的运行信息保存在内存中,这种方法提供了最佳的性能,因为内存中数据访问最快。不足之处是缺乏数据的持久性,当程序路途停止或系统崩溃时,所有运行的信息都会丢失。

  1. JobStoreTX

所有的任务信息都会保存到数据库中,可以控制事物,还有就是如果应用服务器关闭或者重启,任务信息都不会丢失,并且可以恢复因服务器关闭或者重启而导致执行失败的任务。

实现案例 - 单实例方式

本例将展示quartz实现单实例方式。

  • 引入POM依赖
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
</dependency>
复制代码
  • 定义Job

只需要继承QuartzJobBean,并重载executeInternal方法即可定义你自己的Job执行逻辑。

@Slf4j
public class HelloJob extends QuartzJobBean {

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        // get parameters
        context.getJobDetail().getJobDataMap().forEach(
                (k, v) -> log.info("param, key:{}, value:{}", k, v)
        );
        // your logics
        log.info("Hello Job执行时间: " + new Date());
    }
}
复制代码
  • 配置Job

JobDetail, Trigger, Schedule(这里采用CronScheduleBuilder)

/**
 * @author pdai
 */
@Configuration
public class QuartzConfig {

    @Bean("helloJob")
    public JobDetail helloJobDetail() {
        return JobBuilder.newJob(HelloJob.class)
                .withIdentity("DateTimeJob")
                .usingJobData("msg", "Hello Quartz")
                .storeDurably()//即使没有Trigger关联时,也不需要删除该JobDetail
                .build();
    }

    @Bean
    public Trigger printTimeJobTrigger() {
        // 每秒执行一次
        CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule("0/1 * * * * ?");
        return TriggerBuilder.newTrigger()
                .forJob(helloJobDetail())
                .withIdentity("quartzTaskService")
                .withSchedule(cronScheduleBuilder)
                .build();
    }
}
