Error applying BeanValidation relational constraints错误的解决方案

昨天进行hibernate反向工程，完毕后相对生成的东西进行测试，结果一运行

解决方案为：

在hibernate.cfg.xml中配置

     <property name="javax.persistence.validation.mode">
   none
  </property>

  javax.persistence.validation.mode默认情况下是auto的，就是说如果不设置的话它是会自动去你的classpath下面找一个bean-validation**包，
  但是找不到，所以beanvalitionFactory错误
