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：http://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https://www.cnblogs.com/jijm123/p/14240320.html
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:
- 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。
- 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>
- 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());
}
}
- 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();
}
}
