How to stop DefaultListableBeanFactory from implicitly creating LocalValidatorFactoryBean instance

问题

I am using Spring 3.1 and have the following spring config where I explicitly create LocalValidatorFactoryBean using my own ValidationMessageSource. I have Hibernate Validator 4.1 in my class path.

<bean id="messageSource"
      class="org.springframework.context.support.ResourceBundleMessageSource">
    <property name="basenames">
        <list>
            <value>ValidatorMsgID</value>
        </list>
    </property>
</bean>

<bean id="validator"
      class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
    <property name="validationMessageSource" ref="messageSource"/>
</bean>

<bean class="org.springframework.validation.beanvalidation.MethodValidationPostProcessor"/>

However I noticed that the LocalValidatorFactoryBean is being created twice by hitting a debug in classes afterPropertiesSet method. The first time is for the explicite bean that I defined in the spring config, however following that the same class is instantiated implicitly again by DefaultListableBeanFactory class - obviously this time with no validationMessageSource. Therefore it seems that when Spring does make use of the LocalValidatorFactoryBean its using the one with the default Hibernates messagesource rather than the one I have specified.

Ok, looking into this a bit further its seems that this is caused by mvc:annotation-driven I have in the spring config. Any pointers would still help

Ok, I got it sorted eventually by adding the validator attribute to "mvc:annotation-driven". This is how my final spring config looks

<bean id="messageSource"
      class="org.springframework.context.support.ResourceBundleMessageSource">
    <property name="basenames">
        <list>
            <value>com.mycompany.msgs.ValidatorMsgID</value>
        </list>
    </property>
</bean>

<bean id="validator"
      class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
    <property name="messageInterpolator">
        <bean class="org.hibernate.validator.messageinterpolation.ResourceBundleMessageInterpolator">
            <constructor-arg index="0">
                <bean class="org.springframework.validation.beanvalidation.MessageSourceResourceBundleLocator">
                    <constructor-arg index="0" ref="messageSource"/>
                </bean>
            </constructor-arg>
        </bean>
    </property>
</bean>

<bean class="org.springframework.validation.beanvalidation.MethodValidationPostProcessor">
    <property name="validator" ref="validator"/>
</bean>

<mvc:annotation-driven validator="validator"/>
