quartz的奇怪问题!!

[demo大师粉丝]

采用的环境是spring4.0.2 quartz是2.2.1

配置如下：
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">

<property name="configLocation" value="classpath:quartz.properties"/>
<!--这个是必须的，QuartzScheduler 延时启动，应用启动完后 QuartzScheduler 再启动 -->
<property name="startupDelay" value="3"/>
<!--这个是可选，QuartzScheduler 启动时更新己存在的Job，这样就不用每次修改targetObject后删除qrtz_job_details表对应记录了 -->
<property name="overwriteExistingJobs" value="true"/>

<property name="triggers">
<list>
<ref bean="trigger1" />
</list>
</property>
</bean>
<bean id="jobDetail1" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
<property name="durability" value="true"></property>
<property name="jobClass">
<value>com.test.report.countData.job.Job1</value>
</property>
</bean>
<bean id="trigger1" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="jobDetail1"/>
<property name="cronExpression" value="0/5 * * * * ?"></property>
</bean>

任务类：
public class Job1 extends QuartzJobBean {

private static int i = 0;

// 调度工厂实例化后，经过timeout时间开始执行调度
public void setTimeout(int timeout) {
}

/**
* 要调度的具体任务
*/
@Override
protected void executeInternal(JobExecutionContext context)
throws JobExecutionException {

System.out.println("继承QuartzJobBean的方式-调度" + ++i + "进行中...");
}
}

----------------------------------------------------------------------------
启动时，可以打印这个（因为我开启了延时启动）：
[2014-08-19 14:08:45] [SchedulerFactoryBean] [INFO] : Starting Quartz Scheduler now, after delay of 3 seconds


但自定义任务却不能运行，为什么？
