spring quartz 集群模式
本文是基于quartz-1.6.6版本
当我们用到集群模式部署项目的时候就要考虑到定时任务的集群问题，
这里有四种解决方案：
第一：自己通过代码实现（比如通过不同机器的jvm参数配置或者自己建立任务表去控制执行）
第二：确保一台机器启动quartz
第三：将quartz单独抽取部署单实例
第四：用quartz自身提供的解决方案
本文采用方案四。
quartz集群各节点之间是通过同一个数据库实例的同一套表来感知彼此的。
第一步：创建quartz所需的表：
sql文件位于：quartz-1.6.6\docs\dbTables，选择自己的数据库类型对应的sql文件进行创建。
第二步：配置quartz.properties文件，quartz-1.6.6.zip\src\testrig\quartz.properties是个比较完整的demo文件，可以拿来直接修改，修改过后放到自己项目的类目目录下即可。
这里贴出我的项目的该配置文件，项目用的是oracle数据库、weblogic服务器。具体配置项的不再做过多解释
第三步：配置spring的bean
至此，大功告成！

/**
* 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.
