关于Srping定时器jobClass的一个问题，在线等....[
在tomcat启动的时候，class属性被识别为String属性的变量，导致启动不成功，急求解决方案，在线等.....
代码如下：
<bean id="clearDataTimerJob1" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass">
<value >cn.com.task.timer.run.ClearTaskTimer</value>
</property>
<property name="jobDataAsMap">
<map>
<entry key="dataSource">
<ref bean="AA_2" />
</entry>
<entry key="dirHome">
<value>/usr/local/DD/ZIP/export/SS/</value>
</entry>
<entry key="threadName">
<value>线程1...............</value>
</entry>
</map>
</property>
</bean>
报错信息如下：

------解决方案--------------------
Caused by: java.lang.ClassNotFoundException: cn.com.task.timer.run.ClearTaskTimer
检查下地址
------解决方案--------------------
<property name="jobClass">
<value >cn.com.task.timer.run.ClearTaskTimer</value>
</property>
 换成

<property name="
