为什么要有集群定时任务?
因为如果多server都触发相同任务,又同时执行,那在99%的场景都是不适合的.比如银行每晚24:00都要汇总营业额.像下面3台server同时进行汇总,最终计算结果可能是真实结果的3倍,那对银行来说是无法想象的,完全不可接受.
集群定时任务工作原理
所以为了解决以上问题,每个server把将要及正在运行的job所有状态都即时同步到*数据库,然后再次触发调用时从数据库中分析是否已有别的server正在运行相同job (同名同定时时间点的job属于相当job),如果相同job正在别的server运行,那么当前server忽略本次运行的job.
Quartz的 Task（11 张表）实例化采用数据库存储，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。

被修改后的MethodInvokingJobDetailFactoryBean
因为spring自带的org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean的invoke()方法不能序列化job,导致无法把序列化后的信息写到表中,这可以算是spring的一个bug.
所以有民间大神修改后的MethodInvokingJobDetailFactoryBean,该Bean的invoke()方法可使job序列化,2拿来直接上手用吧(注意按包路径要和applicationContext-quartz.xml文件中的路径一致)

* 该类可让生成的job可以序列化到数据库中,Spring自带的MethodInvokingJobDetailFactoryBean却不能序列化生成的job
* This is a cluster safe Quartz/Spring FactoryBean implementation, which produces a JobDetail implementation that can invoke any no-arg method on any Class.
* <p>
* Use this Class instead of the MethodInvokingJobDetailBeanFactory Class provided by Spring when deploying to a web environment like Tomcat.
* <p>
* <b>Implementation</b><br>
* Instead of associating a MethodInvoker with a JobDetail or a Trigger object, like Spring's MethodInvokingJobDetailFactoryBean does, I made the [Stateful]MethodInvokingJob, which is not persisted in the database, create the MethodInvoker when the [Stateful]MethodInvokingJob is created and executed.
* <p>
* A method can be invoked one of several ways:
* <ul>
* <li>The name of the Class to invoke (targetClass) and the static method to invoke (targetMethod) can be specified.
* <li>The Object to invoke (targetObject) and the static or instance method to invoke (targetMethod) can be specified (the targetObject must be Serializable when concurrent=="false").
* <li>The Class and static Method to invoke can be specified in one property (staticMethod). example: staticMethod = "example.ExampleClass.someStaticMethod"
* <br><b>Note:</b> An Object[] of method arguments can be specified (arguments), but the Objects must be Serializable if concurrent=="false".
* </ul>
* <p>
* I wrote MethodInvokingJobDetailFactoryBean, because Spring's MethodInvokingJobDetailFactoryBean does not produce Serializable
* JobDetail objects, and as a result cannot be deployed into a clustered environment like Tomcat (as is documented within the Class).
* <p>
* <b>Example</b>
* <code>
* <ul>
* <bean id="<i>exampleTrigger</i>" class="org.springframework.scheduling.quartz.CronTriggerBean">
* <ul>
<i><!-- Execute example.ExampleImpl.fooBar() at 2am every day --></i><br>
<property name="<a href="http://www.opensymphony.com/quartz/api/org/quartz/CronTrigger.html">cronExpression</a>" value="0 0 2 * * ?" /><br>
<property name="jobDetail">
<ul>
<bean class="frameworkx.springframework.scheduling.quartz.<b>MethodInvokingJobDetailFactoryBean</b>">
<ul>
<property name="concurrent" value="<i>false</i>"/><br>
<property name="targetClass" value="<i>example.ExampleImpl</i>" /><br>
<property name="targetMethod" value="<i>fooBar</i>" />
</ul>
</bean>
</ul>
</property>
</ul>
</bean>
<p>
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<ul>
<property name="triggers">
<ul>
<list>
<ul>
<ref bean="<i>exampleTrigger</i>" />
</ul>
</list>
</ul>
</property>
</ul>
</bean>
</ul>
* </code>
* In this example we created a MethodInvokingJobDetailFactoryBean, which will produce a JobDetail Object with the jobClass property set to StatefulMethodInvokingJob.class (concurrent=="false"; Set to MethodInvokingJob.class when concurrent=="true"), which will in turn invoke the static <code>fooBar</code>() method of the "<code>example.ExampleImpl</code>" Class. The Scheduler is the heart of the whole operation; without it, nothing will happen.

遇见异常
异常一 No row exists in table QRTZ_LOCKS for lock named: TRIGGER_ACCESS.
该异常产生原因是,我项目中用的是quartz-1.8.6的jar,但由于quartz版本差异过大,在不知情的情况下从官网down了最新的quartz-2.2.3且把2.2.3的dbTables文件夹下的tables_oracle.sql导了进来.所以最终和1.8.6的表结构不一致.
就目前来看quartz-2.2.3的tables_oracle.sql比1.8.6的合理很多,1.8.6建表始化时还会建一些尴尬的外键关联,这是让我极不喜欢的一点.
异常如下,请点击展开

异常二 在xml配置中把定时任务的配置全删了,竟然还是执行了
这是spring的一个bug，所以需要去查询这三张表,它们储存了定时任务,把相关的定时任务删了即可
delete from QRTZ_CRON_TRIGGERS where TRIGGER_NAME = 'echannel.synchronizeJobTrigger'; delete from QRTZ_TRIGGERS where TRIGGER_NAME = 'echannel.synchronizeJobTrigger'; delete from QRTZ_JOB_DETAILS where job_name = 'echannel.synchronize.content';
其它无关紧要的资料
SimpleTriggerBean
简易版Spring触发器,功能和org.springframework.scheduling.quartz.CronTriggerBean相似
<!-- ClusterSimpleTriggerBean 未使用,被注释了 -->
<bean id="clusterSimpleTriggerBean" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
<property name="startDelay" value="10000" />
<property name="repeatInterval" value="10000" />
<property name="jobDetail" ref="clusterJobDetail" />
</bean>
参考
Spring+quartz集群配置，Spring定时任务集群，quartz定时任务集群(强烈推荐)
