Spring调度问题。

  我在用quartz-all-1.6.0是，出现一下异常

at java.lang.Thread.run(Unknown Source)    对应的quartz-all-1.6.0配置文件如下：
        <bean id="cronQuartzClock"
class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail">
<ref bean="quartzClock"></ref>
</property>
<property name="cronExpression">
<value>0 1 * * * ?</value>
</property> </bean>
<!--第三步 启动定时任务,注意这里的ref bean org.springframework.scheduling.quartz.SchedulerFactoryBean-->
<bean
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="cronQuartzClock"></ref>
</list>
</property>
</bean>
       但我不加这配置文件时候不出错，能很好运行，但一加这段就出现异常，请高手们指点指点。

解决方案 »

  1.   

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'quartzClock' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Instantiation of bean failed;quartzClock这个Bean实例失败,看下你这个Bean是如何配置的,看配置有没有问题
      

  2.   

    <ref bean="quartzClock"> </ref> 
    这个bean怎么配的呢
    Error creating bean with name 'quartzClock' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.scheduling.quartz.QuartzJobBean]: Is it an abstract class?; nested exception is java.lang.InstantiationException这段应该是关键
      

  3.   

    前面还有一段配置文件：
       <bean id="quartzClock" class="org.springframework.scheduling.quartz.QuartzJobBean">
    <property name="jobClass">
    <value>hesom.com.util.TimeMap</value>
    </property>
    </bean>
      

  4.   

     Could not instantiate bean class [org.springframework.scheduling.quartz.QuartzJobBean]: Is it an abstract class?; 
    不能够实例化
    quartzClock 这是个abstract class ?
      

  5.   

    没有呀，我只是继承了org.springframework.scheduling.quartz.QuartzJobBean
