quartz （从原理到实战）

一、Quartz 基本介绍

1.1 Quartz 概述
Quartz 是 OpenSymphony 开源组织在任务调度领域的一个开源项目，完全基于 Java 实现。该项目于 2009 年被 Terracotta 收购，目前是 Terracotta 旗下的一个项目。读者可以到 http://www.quartz-scheduler.org/站点下载 Quartz 的发布版本及其源代码。
1.2 Quartz特点

• 强大的调度功能，例如支持丰富多样的调度方法，可以满足各种常规及特殊需求；
• 灵活的应用方式，例如支持任务和调度的多种组合方式，支持调度数据的多种存储方式；
• 分布式和集群能力，Terracotta 收购后在原来功能基础上作了进一步提升。
• 作为 Spring 默认的调度框架，Quartz 很容易与 Spring 集成实现灵活可配置的调度功能。quartz调度核心元素：
• Scheduler:任务调度器，是实际执行任务调度的控制器。在spring中通SchedulerFactoryBean封装起来。
• Trigger：触发器，用于定义任务调度的时间规则，有SimpleTrigger,CronTrigger,DateIntervalTrigger和NthIncludedDayTrigger，其中CronTrigger用的比较多，本文主要介绍这种方式。CronTrigger在spring中封装在CronTriggerFactoryBean中。
• Calendar:它是一些日历特定时间点的集合。一个trigger可以包含多个Calendar，以便排除或包含某些时间点。
• JobDetail:用来描述Job实现类及其它相关的静态信息，如Job名字、关联监听器等信息。在spring中有JobDetailFactoryBean和 MethodInvokingJobDetailFactoryBean两种实现，如果任务调度只需要执行某个类的某个方法，就可以通过MethodInvokingJobDetailFactoryBean来调用。
• Job：是一个接口，只有一个方法void execute(JobExecutionContext context),开发者实现该接口定义运行任务，JobExecutionContext类提供了调度上下文的各种信息。Job运行时的信息保存在JobDataMap实例中。实现Job接口的任务，默认是无状态的，若要将Job设置成有状态的，在quartz中是给实现的Job添加@DisallowConcurrentExecution注解（以前是实现StatefulJob接口，现在已被Deprecated）,在与spring结合中可以在spring配置文件的job detail中配置concurrent参数。

1.3 Quartz 集群配置
quartz集群是通过数据库表来感知其他的应用的，各个节点之间并没有直接的通信。只有使用持久的JobStore才能完成Quartz集群。
数据库表：以前有12张表，现在只有11张表，现在没有存储listener相关的表，多了QRTZ_SIMPROP_TRIGGERS表：

QRTZ_LOCKS就是Quartz集群实现同步机制的行锁表,包括以下几个锁：CALENDAR_ACCESS 、JOB_ACCESS、MISFIRE_ACCESS 、STATE_ACCESS 、TRIGGER_ACCESS。

二、Quartz 原理

2.1 quartz基本原理
核心元素
Quartz 任务调度的核心元素是 scheduler, trigger 和 job，其中 trigger 和 job 是任务调度的元数据， scheduler 是实际执行调度的控制器。

在 Quartz 中，trigger 是用于定义调度时间的元素，即按照什么时间规则去执行任务。Quartz 中主要提供了四种类型的 trigger：SimpleTrigger，CronTirgger，DateIntervalTrigger，和 NthIncludedDayTrigger。这四种 trigger 可以满足企业应用中的绝大部分需求。我们将在企业应用一节中进一步讨论四种 trigger 的功能。

在 Quartz 中，job 用于表示被调度的任务。主要有两种类型的 job：无状态的（stateless）和有状态的（stateful）。对于同一个 trigger 来说，有状态的 job 不能被并行执行，只有上一次触发的任务被执行完之后，才能触发下一次执行。Job 主要有两种属性：volatility 和 durability，其中 volatility 表示任务是否被持久化到数据库存储，而 durability 表示在没有 trigger 关联的时候任务是否被保留。两者都是在值为 true 的时候任务被持久化或保留。一个 job 可以被多个 trigger 关联，但是一个 trigger 只能关联一个 job。

在 Quartz 中， scheduler 由 scheduler 工厂创建：DirectSchedulerFactory 或者 StdSchedulerFactory。 第二种工厂 StdSchedulerFactory 使用较多，因为 DirectSchedulerFactory 使用起来不够方便，需要作许多详细的手工编码设置。 Scheduler 主要有三种：RemoteMBeanScheduler， RemoteScheduler 和 StdScheduler。本文以最常用的 StdScheduler 为例讲解。这也是笔者在项目中所使用的 scheduler 类。
