续:上面只是quartz的独立应用,如何将它整合到实际的项目应用中了。
在原有的ssh基础上,加入quartz.xml(在这里面配置所需的任务调度),
再在web.xml文件contextConfigLocation下param-value中追加classpath*:quartz.xml
结构图、文件如下
quartz.xml
- <? xml version = "1.0" encoding = "UTF-8" ?>
- < beans
- xmlns = "http://www.springframework.org/schema/beans"
- xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
- xsi:schemaLocation = "http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd" >
- <!-- 对 testService 中的 testQuartz 方法进行定时任务调度 -->
- < bean id = "methodInvokingJobDetailForSms" class = "org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" >
- < property name = "targetObject" >
- < ref bean = "testService" />
- </ property >
- < property name = "targetMethod" >
- < value > testQuartz </ value >
- </ property >
- </ bean >
- < bean id = "cronTriggerForSms" class = "org.springframework.scheduling.quartz.CronTriggerBean" >
- < property name = "jobDetail" >
- < ref bean = "methodInvokingJobDetailForSms" />
- </ property >
- < property name = "cronExpression" >
- < value > 0 * 12 * * ? </ value >
- </ property >
- </ bean >
- < bean class = "org.springframework.scheduling.quartz.SchedulerFactoryBean" >
- < property name = "triggers" >
- < list >< ref local = "cronTriggerForSms" /></ list >
- </ property >
- </ bean >
- </ beans >
web.xml
- < context-param >
- < param-name > contextConfigLocation </ param-name >
- <!-- <param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value> -->
