最为罕用定时工作框架是 Quartz，并且 Spring 也集成了 Quartz 的框架，Quartz 不仅反对单实例形式还反对分布式形式。本文次要介绍 Quartz，根底的 Quartz 的集成案例本，以及实现基于数据库的分布式工作治理和管制 job 生命周期。@pdai

筹备知识点

须要理解罕用的 Quartz 框架。

什么是 Quartz

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

Quartz 是 OpenSymphony 开源组织在 Job scheduling 畛域又一个开源我的项目，它能够与 J2EE 与 J2SE 应用程序相结合也能够独自应用。Quartz 能够用来创立简略或为运行十个，百个，甚至是好几万个 Jobs 这样简单的程序。Jobs 能够做成规范的 Java 组件或 EJBs。

它的特点如下

  • 纯 java 实现，能够作为独立的应用程序，也能够嵌入在另一个独立式利用程序运行
  • 弱小的调度性能，Spring 默认的调度框架，灵便可配置；
  • 作业长久化，调度环境长久化机制，能够保留并复原调度现场。零碎敞开数据不会失落；灵便的利用形式，能够任意定义触发器的调度时间表，反对工作和调度各种组合，组件式监听器、各种插件、线程池等性能，多种存储形式等；
  • 分布式和集群能力，能够被实例化，一个 Quartz 集群中的每个节点作为一个独立的 Quartz 应用，通过雷同的数据库表来感知到另一个 Quartz 利用

Quartz 的体系结构

  • Job 示意一个工作，要执行的具体内容。
  • JobDetail 示意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 还蕴含了这个任务调度的计划和策略。
  • 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，一个调度容器中能够注册多个 JobDetail 和 Trigger。当 Trigger 与 JobDetail 组合，就能够被 Scheduler 容器调度了。

注：上图来源于 https://www.cnblogs.com/jijm1…

什么是 Quartz 长久化

  • 为什么要长久化 ？

当程序忽然被中断时，如断电，内存超出时，很有可能造成工作的失落。能够将调度信息存储到数据库外面，进行长久化，当程序被中断后，再次启动，依然会保留中断之前的数据，继续执行，而并不是从新开始。

  • Quartz 提供了两种长久化形式

Quartz 提供两种根本作业存储类型:

  1. RAMJobStore

在默认状况下 Quartz 将任务调度的运行信息保留在内存中，这种办法提供了最佳的性能，因为内存中数据拜访最快。不足之处是不足数据的持久性，当程序道路进行或零碎解体时，所有运行的信息都会失落。

  1. JobStoreTX

所有的工作信息都会保留到数据库中，能够管制事物，还有就是如果应用服务器敞开或者重启，工作信息都不会失落，并且能够复原因服务器敞开或者重启而导致执行失败的工作。

实现案例 – 单实例形式

本例将展现 quartz 实现单实例形式。

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

只须要继承 QuartzJobBean，并重载 executeInternal 办法即可定义你本人的 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 执行工夫:" + new Date());
    }
}
  • 配置 Job

JobDetail, Trigger, Schedule(这里采纳 CronScheduleBuilder)

/**
 * @author pdai
 */
@Configuration
public class QuartzConfig {@Bean("helloJob")
    public JobDetail helloJobDetail() {return JobBuilder.newJob(HelloJob.class)
                .withIdentity("DateTimeJob")
                .usingJobData("msg", "Hello Quartz")
                .storeDurably()// 即便没有 Trigger 关联时，也不须要删除该 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();}
}
