cron 定时任两种配置方式

第一种：xml文件方式

    
<bean id="commonTimer" class="com.course.wx.timer.CommonTimer"></bean><!--定时任务Bean -->
<bean name="startQuartz" lazy-init="false" autowire="no"  class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
            <property name="triggers">
                <list>
                    <ref bean="releaseQuestionTrigger" />
                    <ref bean="dealHistoryQuestionTrigger" />
                </list>
            </property>
        </bean>

 <bean id="dealHistoryQuestionTrigger"
          class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail">
            <ref bean="dealHistoryQuestion" />
        </property>
        <property name="cronExpression">
            <value>0 23 15 * * ?</value>
        </property>
</bean>


<bean id="dealHistoryQuestion"
          class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject">
            <ref bean="commonTimer" />
        </property>
        <property name="targetMethod">
            <value>dealHistoryQuestion</value>
        </property>
</bean>

第二种：注解方式

xml配置

    <!-- Spring定时器注解开关-->  
    <task:annotation-driven />
    <!-- 此处对于定时时间的配置会被注解中的时间配置覆盖，因此，以注解配置为准 -->  
    <task:scheduled-tasks scheduler="myScheduler">  
        <task:scheduled ref="scheduledTaskManager" method="autoCardCalculate" cron="* */5 * * * *"/>  
    </task:scheduled-tasks>  
    <task:scheduler id="myScheduler" pool-size="10"/>

Java代码

@Component("scheduledTaskManager")
@Lazy(value=false)
public class ScheduledTaskManager { 
    
    public static final Integer RECOVER = 3;
    /** 
     * cron表达式：* * * * * *（共6位，使用空格隔开，具体如下） 
     * cron表达式：*(秒0-59) *(分钟0-59) *(小时0-23) *(日期1-31) *(月份1-12或是JAN-DEC) *(星期1-7或是SUN-SAT) 
     */  
    @Autowired
    ProcedureService procedureService;
  
    /** 
     * 定时卡点计算。每天凌晨 02:00 执行一次 
     * @throws AdqException 
     */  
    @Scheduled(cron = "* */5 * * * *")  
    public void autoCardCalculate() throws AdqException {  
        List<WorkOrder> suspendItems = procedureService.querySuspendItems();
        if (suspendItems != null && suspendItems.size() > 0) {
            for (WorkOrder order : suspendItems) {
                order.setStateId(RECOVER);
                order.setNotes("恢复执行");
                procedureService.updateState(order);
            }
        }
    }  
}
