Error applying BeanValidation relational constraints

org.hibernate.HibernateException: Error applying BeanValidation relational constraints
	at org.hibernate.cfg.beanvalidation.BeanValidationIntegrator.applyRelationalConstraints(BeanValidationIntegrator.java:219)

hibernate4.0.1
자바 때문에.persistence.validation.모드의 속성 값은 기본적으로 auto이기 때문에 오류가 발생합니다.
hibernate에서.cfg.xml에서javax를persistence.validation.mode를 none로 설정하면 됩니다.

<bean id="sessionFactory"
      class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="hibernateProperties">
        <props>
            ....
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>
