最近开发一个文档系统，要实现定时搜索数据库并且发送通知邮件。加入了quartz之后，每分钟定时执行一次，发现系执行了60次左右，系统就会报内存益出。

具体代码如下：

applicationContext.xml配置

<beanid="scheduledJob"class="org.springframework.scheduling.quartz.JobDetailBean">

<propertyname="jobClass"value="javaoa.util.ScheduledJob"/>

</bean>

<beanid="timerTrigger"class="org.springframework.scheduling.quartz.CronTriggerBean">

<propertyname="jobDetail">

<refbean="scheduledJob"/>

</property>

<propertyname="cronExpression"value="0****?"/>

</bean>

<beanid="TimerTaskFactory"class="org.springframework.scheduling.quartz.SchedulerFactoryBean">

<propertyname="triggers">

<list>

<refbean="timerTrigger"/>

</list>

</property>

</bean>

</beans>
