spring的BeanDefinitionParsingException异常

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unnamed bean definition specifies neither 'class' nor 'parent' nor 'factory-bean' - can't generate bean name
异常产生原因

spring的applicationContext.xml中定义bean节点的错误

比如

<bean id="commonDao"></bean>

或

<bean></bean>

bean节点没有class，parent或factory-bean就会报出这种错误

改为类似

<bean id="commonDao" class="com.CommonDao"></bean>

之后就不会有该错误
