org.springframework.beans.factory.BeanCreationException:。。。FactoryBean which is currently in creatio

Error creating bean with name ‘doubanJob’: FactoryBean which is currently in creation returned null from getObject

    <bean id="doubanJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="doubanJob">property>
        <property name="targetMethod" value="myTask">property>
    bean>

    <bean id="doubanTigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="doubanJob">property>
        
        <property name="cronExpression" value="0/20 * * * * ?">property>
    bean>
    

上面代码中，配置，id与ref同名了，改成不同的名字就好了
