quartz 不执行也不报错是怎么回事

<!-- 调度任务 -->
<bean id="task" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass" value="com.sms.util.EveryWeekTask"></property>
</bean>

<!-- 按频率调度 -->
<bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
<property name="jobDetail" ref="task"></property>

<property name="repeatCount" value="3"></property>

<property name="repeatInterval" value="20"></property>
</bean>
<!-- 按时间点调度 -->
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">

任务类
public class EveryWeekTask extends QuartzJobBean{

@Override
protected void executeInternal(JobExecutionContext arg0)
throws JobExecutionException {
System.out.println("111111");
}

}

不执行也不报错
