项目经验：项目预警定时器配置要点总结

在web.xml下

<!-- context-param是配置Spring的applicationContext文件，如果不配默认位置是WEB-INF下的applicationContext.xml文件 -->

<context-param >

<param-name >contextConfigLocation </param-name >

<param-value >

classpath*:configs /applicationContext-app.xml

</param-value >

</context-param >

<listener >

<listener-class >org.springframework.web.context.ContextLoaderListener </listener-class >

</listener >

在applicationContext-app.xml 下

<!-- 启动定时器 -->

<bean class= "org.springframework.scheduling.quartz.SchedulerFactoryBean" >

<property name ="triggers">

<list >

<ref local ="projectEsWarningTrigger"/>

<ref local ="dataDelayWarningTrigger"/>

</list >

</property >

</bean >

<!-- 定义我们要运行的类，可以使用注入，定制一些参数    项目超标预警-->

<bean id ="projectEsWarning" class= "com.richway.rtmonitor.util.ProjectESWarning" >

<property name ="param" value="Spring定时器配置项目超标预警" ></property >

<property name ="yjlsxxService" ref="yjlsxxService"/>

<!-- 定义我们要运行的类，可以使用注入，定制一些参数    数据延迟预警-->

</bean >

<!-- 引用、配置要运行的方法   项目超标预警-->

<bean id ="projectEsWarningDetail" class= "org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" >

<!-- 目标对象 -->

<!-- 指定任务类 -->

<property name ="targetObject">

<ref bean ="projectEsWarning"/>

</property >

<!-- 是否同时发生 -->

<property name ="concurrent" value="false"></ property>

<!-- 目标方法 -->

<property name ="targetMethod" value="run"></ property>

<!-- 引用、配置要运行的方法   数据延迟预警-->

<property name ="cronExpression">

<!-- 引用、定制时间间隔  数据延迟预警 中午12点 以及 晚上12点 执行各执行一次  下面被注释掉的那一行就是凌晨0点 中午12点 各执行一次  另外一行 下午三点 每隔5分钟 执行一次 只是为了测试用-->

<value >0 5,10,15,20,25,30,35,40,45,50,55 15 * * ?</value>
