如何阻止DefaultListableBeanFactory隐式创建LocalValidatorFactoryBean实例

Question

我正在使用Spring 3.1并使用以下spring配置,我LocalValidatorFactoryBean使用自己的显式创建ValidationMessageSource.我的类路径中有Hibernate Validator 4.1.

<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"/>

但是我注意到,LocalValidatorFactoryBean通过在类afterPropertiesSet方法中调试调试来创建两次.第一次是我在spring配置中定义的explicite bean,但是随后同一个类被类隐式重新实例化DefaultListableBeanFactory- 显然这次没有validationMessageSource.因此,当Spring确实使用LocalValidatorFactoryBean默认Hibernates messagesource而不是我指定的那个时使用它.

好吧,进一步研究它似乎这是由mvc:annotation-driven我在spring配置中引起的.任何指针仍然会有所帮助

好吧,我最终通过将validator属性添加到"mvc:annotation-driven"来对其进行排序.这是我的最终spring配置的外观

<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"/>
