java Spring定时任务详解

1.创建一个调用业务层的类并要继承QuartzJobBean

例：Object obj = SpringContextUtil.getBean("tOrderService");   //获取spring实例bean

public class ConfirmOrderStateJob extends QuartzJobBean { @Override protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException { Object obj = SpringContextUtil.getBean("tOrderService"); if (null != obj) {// 非空再进行业务处理 TOrderService tOrderService = (TOrderService) obj; tOrderService.doConfirmOrderStateJob(); } } }

2.创建一个properties文件

例如：quartz.properties

在xml文件中会被引用到

内容：如下例子

org.quartz.scheduler.instanceName = DefaultQuartzScheduler org.quartz.scheduler.rmi.export = false org.quartz.scheduler.rmi.proxy = false org.quartz.scheduler.wrapJobExecutionInUserTransaction = false org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount = 1 org.quartz.threadPool.threadPriority = 5 org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true org.quartz.jobStore.misfireThreshold = 60000 org.quartz.jobStore.class =org.quartz.simpl.RAMJobStore

3.创建xml文件  

例如：frame-quartz-context.xml

内容：如下例子

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <!--**************************************单机配置，每台节点均运行********************************--> <!-- 统计定时任务--> <bean id="newAcess" class="org.springframework.scheduling.quartz.JobDetailBean"> <property name="jobClass"> <value>com.yxd.pris.common.job.ConfirmOrderStateJob</value> </property> </bean> <!-- 统计访问sesion，每2分钟运行一次--> <bean id="cronnewNewAcess" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail" ref="newAcess" /> <property name="cronExpression" value="0 */2 * * * ?" /> </bean> <bean name="quartzSchedulerAccess" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="applicationContextSchedulerContextKey" value="applicationContextKey" /> <property name="configLocation" value="classpath:cfg/quartz_access.properties" /> <property name="triggers"> <list> <ref bean="cronnewNewAcess" /> </list> </property> <property name="autoStartup" value="true"></property> </bean> </beans>

4.实现业务逻辑
