Spring中Quartz2.2.2的使用

本文介绍的内容为, 在spring管理的项目中使用Quartz2.2.2版本进行任务调度

quartz 非教学介绍

quartz是一款基于java timer开发的一个轻量级任务调度框架, 可以帮助我们快速实现定时/周期任务处理工具组件

Quartz中有任务组, 任务, 触发器组, 触发器 cron expression 等概念.
JOB_GROUP 、JOB 、TRIGGER_GROUP 、TRIGGER 、CRON

顾名思义任务组对应任务, 触发器组对应触发器, 目前实战项目中的用法比较特殊.

我们使用一个任务, 对应多个触发器来达到任务调度的实现.当前Quartz支持两种任务配置, 这里使用的是以任务为单位来进行定时执行的概念, 还有一种指定service方法来执行, 具体大家可以参考其他博主的文章自行了解.

注意!!! Quartz版本2.x以后,不支持向下兼容, 此文所用Quartz为2.2.2

常用类及API

JobDetail、JobBuilder、TriggerBuilder、Scheduler、CronTrigger、CronScheduleBuilder

相互之间的关系

任务调度器 Scheduler 内可以存在多个任务 JobDetail 任务内可以存在多个触发器来调起这个任务来进行任务的执行

Scheduler

Trigger1
Trigger2
Trigger3
JobDetail

任务的最小单元。该类主要记录任务信息

Trigger

任务的执行时机，触发的时点

代码示例

创建一个任务

/*
 * Quartz 2.x 以后版本,JobDetail由类, 上升成为了接口,对应的实现为JobDetailImpl
 * 但Quartz并不推荐使用JobDetailImpl直接获取到Job对象
 * Quartz提供了构建者模式创建对象
 * 其中包含这里看到的任务构建器, 以及后面得到触发器构建器
 *
 * 这里说明一下构建器的几个参数, 通过阅读源码我们可以发现,
 * Job构建器需要指定一个任务的class路径作为一个构建者的标注, 然后依次属性durably
 * 任务是否进行持久化, 默认为false, 这里后面我们可以通过观察qrtz_job_details中is_durably字段
 * 数据变化来检查对应任务的设置情况. 接着requestRecovery属性为是否记录任务执行状态,
 * 比如中断后, 重启应用后是否继续执行,默认为false,对应表字段qrtz_job_details中 request_recovery字段
 * 接着后面的 withIdentity 为我们任务的基本信息, 分别为任务名称及任务组
 */
JobDetail jobDetail = JobBuilder.newJob(xsdsJob.getClass())
        .storeDurably().requestRecovery().
                withIdentity(xsdsJob.getJobName(), xsdsJob.getJobGroupName()).build();
try {
    scheduler.addJob(jobDetail, true);
} catch (SchedulerException e) {
    ........
}

为某个任务增加执行时机(触发器)

具体内容参考代码中日志

  try {
  	  // TriggerKey  是作为一个触发器的标识存在的, 通过 TriggerKey 可以定位到一个触发器, 这里使用的参数为触发器所在组及触发器名称
      TriggerKey triggerKey = TriggerKey.triggerKey(trigger.getTriggerName(), trigger.getTriggerGroupName());
	  // 通过使用调度器 scheduler.getTrigger() 方法返回值来获取对应的触发器
      if (scheduler.getTrigger(triggerKey) != null) {
          logger.error("当前任务【" + trigger.getTriggerName() + "】已存在, 无法覆盖创建任务调度计划");
          return;
      }
	  // 触发器构建器
      TriggerBuilder<Trigger> triggerBuilder = TriggerBuilder.newTrigger();
      // 执行时辅助参数
      triggerBuilder.usingJobData(trigger.getParam());
      // 触发器信息
      triggerBuilder.withIdentity(trigger.getTriggerName(), trigger.getTriggerGroupName());
      // 设置后立即启动
      triggerBuilder.startNow();
      // 使用的调度类型, 这里配置为cron表达式触发器
      triggerBuilder.withSchedule(
              CronScheduleBuilder.cronSchedule(trigger.getCron())
                      .withMisfireHandlingInstructionDoNothing());
      // 该触发器所关联的任务
      triggerBuilder.forJob(trigger.getJobName(), trigger.getJobGroupName());
      CronTrigger cronTrigger = (CronTrigger) triggerBuilder.build();
      // 设置触发器
      scheduler.scheduleJob(cronTrigger);
      // 当前调度器是否执行, 如果没执行, 启动该调度器
      if (!scheduler.isShutdown()) {
          scheduler.start();
          logger.info("【" + trigger.getTriggerName() + "】任务调度计划启动成功!");
      }
  } catch (Exception e) {
      throw new RuntimeException(e);
  }

下面一切内容皆建立在Spring管理项目基础上Quartz相关内容

jar包下载

maven

        <dependency>
            <groupId>org.quartz-scheduler</groupId>

配置Quartz文件
  1. 注册调度bean
    <!-- 定时任务配置 -->
    <bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="overwriteExistingJobs" value="true"/>

        <property name="applicationContextSchedulerContextKey" value="applicationContextKey"/>
        <property name="configLocation" value="classpath:conf/common/properties/quartz.properties"/>
    </bean>
  1. Quartz properties(官方默认即可)
