spring + Quartz 设置定时任务时要求没一个半小时执行一次
设置两个相同的定时任务
第一个从整点开始每三小时执行一次
<!--每三小时执行一次任务，从整点开始-->
<property name ="cronExpression" value="0 0 0/3 * * ?"></property>
第二个从一个半小时后开始每三小时执行一次
<!--每三小时执行一次任务，从一个半小时后开始 -->
<property name ="cronExpression" value="0 30 1/3 * * ?"></property>
spring核心代码示例：
<!--获取demoTask定时任务start -->
<bean id ="demoTask" class="com.bdx.itpl.wcpay.quartz.task.OrdinaryAccessTokenAndJsApiTicketTask" />
<bean id ="demoMethod" class= "org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" >
<property name ="targetObject">
<ref bean ="demoTask"/>
</property >
<property name ="targetMethod">
<value >execute </value ><!-- 要执行的方法名称 -->
</property >
</bean >
<bean id ="demoBean" class= "org.springframework.scheduling.quartz.CronTriggerFactoryBean" >
<property name ="jobDetail" ref= "demoMethod" ></property >
<!--每三小时执行一次任务，从整点开始-->
<property name ="cronExpression" value="0 0 0/3 * * ?"></property>
</bean >
<bean id ="demoBean2" class= "org.springframework.scheduling.quartz.CronTriggerFactoryBean" >
<property name ="jobDetail" ref= "demoMethod" ></property >
<!--每三小时执行一次任务，从一个半小时后开始 -->
<property name ="cronExpression" value="0 30 1/3 * * ?"></property>
</bean >
<!--获取OrdinaryAccessTokenAndJsApiTicketTask定时任务end--> <!-- ======================== 调度工厂 ======================== -->
<bean id ="SpringJobSchedulerFactoryBean" class= "org.springframework.scheduling.quartz.SchedulerFactoryBean" >
<property name ="triggers">

<ref bean= "demoBean2" /> </list >
