Using the Quartz Scheduler

참고 http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/scheduling.html

Task

: 업무처리를 위한 단위

  Job에서 사용하게 되는 Bean.

  MethodInvokingJobDetailFactoryBean 클래스를 이용하여 invoke 시킬 수 있음.

Job

: QuartzJobBean 클래스를 상속 받음. 

  protected void executeInternal(JobExecutionContext context) 함수를 Override해서 필요한 로직 처리

예) <bean name="printJob" class="org.springframework.scheduling.quartz.JobDetailBean"> <property name="jobClass" value="com.tistory.codesnippet.schedule.quartz.PrintJob" /> <property name="jobDataAsMap"> <map> <entry key="printTask" value-ref="printTask" /> </map> </property> </bean>  혹은 <bean id="printJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <property name="targetObject" ref="printTask" /> <property name="targetMethod" value="execute" /> </bean>

Trigger

: SimpleTriggerBean과 CronTriggerBean가 있음

  실행시킬 Job 참조필요.

  SimpleTriggerBean은 반복주기, 시작 딜레이 시간을 지정할 수 있음

  CronTriggerBean은 cron 문법을 지원함.

예) <bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean"> <property name="jobDetail" ref="printJob" /> <property name="repeatInterval" value="5000" /> <property name="startDelay" value="1000" /> </bean> <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail" ref="printJob" /> <property name="cronExpression" value="0/5 * * * * ?" /> </bean>

Scheduler

: Trigger를 작동시키는 역활을 함.

  Job을 지정해 줄 수 있음.

<bean name="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <!--  <property name="jobDetails">    <list>       <ref bean="printJob" />    </list> </property>   --> <property name="triggers">     <list> <ref bean="simpleTrigger" /> <!-- <ref bean="cronTrigger" /> -->     </list> </property>   </bean>
