spring-quartz定时任务集群解决方案。

<div id="article_content" class="article_content">

 最近项目中使用了<a target="_blank" href="http://www.52itstyle.com/forum-54-1.html" class="relatedlink"
style="word-wrap:break-word; color:rgb(51,51,51); border-bottom-width:1px; border-bottom-style:solid; border-bottom-color:blue; font-family:'Microsoft YaHei',Tahoma,Helvetica,SimSun,sans-serif; font-size:14px; line-height:21px">spring</a>+Quartz定时任务、但是项目最近要集群部署、多个APP下如何利用Quartz

协调处理任务。 

 大家可以思考一下、现在有 A、B、C三个应用同时作为集群服务器对外统一提供服务、每个应用下各有一个Quartz、它们会按照既定的时间自动执行各自的任务。我们先不说实现什么功能，就说这样的架构其实有点像多线程。那多线程里就会存在“资源竞争”的问题，即可能产生脏读，脏写，由于三台

应用里都有 Quartz，因此会存在重复处理任务的现象。 

 解决方案一：只在一台应用上装 Quartz，其它两台不装，这样集群就没有意义了。 

 解决方案二：使用其实Quartz自身可以实例化数据库的特性就可以解决问题 

本方案优点： 

1. 每台作为集群点的应用上都可以布署 Quartz ； 

2. Quartz 的 TASK （ 12 张表）实例化如数据库，基于数据库引擎及 High-Available 的策略（集群的一种策略）自动协调每个节点的 QUARTZ ，当任一一节点的 QUARTZ
非正常关闭或出错时，另几个节点的

QUARTZ 会自动启动； 

3. 无需开发人员更改原已经实现的 QUARTZ ，使用 SPRING+ 类反射的机制对原有程序作切面重构； 

解决方案： 

 1:去官网下载最新的 quartz 解压在目录 docs\dbTables 下就会找到 tables_mysql.sql 文件、建立数据库Quartz 并导入数据库。

class="zoom" width="437" alt="" style="word-wrap:break-word"> 

 2：生成 quartz.properties 文件，把它放在工程的 src 目录下修改配置文件如下：

3：重写 quartz 的 QuartzJobBean 类 

原因是在使用 quartz+spring 把 quartz 的 task 实例化进入数据库时，会产生： serializable 的错误，原因在于： 

这个 MethodInvokingJobDetailFactoryBean 类中的 methodInvoking 方法，是不支持序列化的，因此在把 QUARTZ 的 TASK 序列化进入数据库时就会抛错。网上有说把 SPRING <a

font-size:14px; line-height:21px">源码</a>拿来，修改一下这个方案，然后再打包成

SPRING.jar 发布，这些都是不好的方法，是不安全的。 

必须根据 QuartzJobBean 来重写一个自己的类。

集群环境下测试： 

 三个个节点都带有 Quartz 任务，监控控制台、此时只有一台 quartz 在运行，另几个节点上的 quartz 没有运行。 

 此时手动停掉那台运行 QUARTZ 过了 10分钟左右，另一个节点的 quartz 自动监测到了集群中运行着的 quartz 的 instance 已经停掉，因此 quartz 集群会自动把任一台可用的 APP上启动起一个 quartz job 的任务。 

 至此 Quartz使用集群策略已经ok，不用改原有代码，配置一下我们就可做到 Quartz的集群与自动错误冗余。
