Question

Spring+quartz 做定时任务时，每5分种执行一次，怎么写法

Answer 1

cron表达式为“0 0/5 * * * ?”
推荐使用maven构建项目，如果你的quartz的版本为2.2.1及以上，
主要的spring applicationContext bean配置如下【2.2版本后配置有些变化】：
bean id="jobDetail"
class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
<property name="jobClass" value="cn.javacoder.test.quartz.HelloJob"/>
<property name="durability" value="true"/>
</bean>

<bean id="trigger_test" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="jobDetail"/>
<property name="cronExpression" value="0 0/5 * * * ?"/>
</bean>

<bean id="startQuertz" lazy-init="false" autowire="no"
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="configLocation" value="classpath:quartz.properties" />
<property name="triggers">
<list>
<ref bean="trigger_test" />
</list>
</property>
<property name="dataSource" ref="dataSource"/>
<property name="waitForJobsToCompleteOnShutdown" value="true"/>
</bean>

Answer 2

<bean id="trigger1" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="job"></property>
<property name="cronExpression" value="0 0/5 * * * ?"></property>
</bean>
