我最终通过将LocalValidatorFactoryBean放入jpaPropertyMap并将其设置在我的LocalContainerEntityManagerFactoryBean上解决了这个问题：
Map<String, LocalValidatorFactoryBean> jpaPropertyMap = new HashMap<>();
jpaPropertyMap.put("javax.persistence.validation.factory", localValidatorFactoryBean);
factoryBean.setJpaPropertyMap(jpaPropertyMap);
Map jpapropertypmap=newhashmap（）；
jpaPropertyMap.put（“javax.persistence.validation.factory”，localValidatorFactoryBean）；
setjpapropertypap（jpapropertypap）；
奇怪的是，文档中没有提到这一点…您能提供stacktrace吗？
