我在Spring MVC项目中使用JSR-303 bean验证。当我在类路径上有一个JSR-303提供程序时，一切正常，并将所有其他验证设置保留为默认模式。我想在我的自定义验证器中使用spring managed beans，所以我将以下配置添加到org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean声明中：
<property name="jpaPropertyMap">
<map>
<entry key="javax.persistence.validation.factory" value-ref="validator" />
</map>
</property>
当使用此配置时，似乎仍然使用@Valid注释的bean仍在MVC控制器中进行验证，但是代替MVC然后捕获验证失败并在表单上显示它们，会导致HTTP 500错误并且我从以下堆栈跟踪中获取Tomcat的：
javax.validation.ConstraintViolationException: Validation failed for classes [xxx.model.WebPage] during update time for groups [javax.validation.groups.Default, ]
List of constraint violations:[
ConstraintViolationImpl{interpolatedMessage='may not be empty', propertyPath=title, rootBeanClass=class xxx.model.WebPage, messageTemplate='{org.hibernate.validator.constraints.NotEmpty.message}'}

有没有人知道为什么Spring在设置javax.persistence.validation.factory属性时不会显示异常而无法处理验证错误？
