以前出现过这个错误，上网科普了下，发现只要给hibernate.cfg.xml全局配置文件加入:

<property name="javax.persistence.validation.mode">none</property>就能解决该异常，

原因：

javax.persistence.validation.mode默认情况是auto状态,也就是说如果不设置为none的话，会自动的去classpath下面找一个bean-validation**的包

,如果没有导入hibernate-validator相关的两个jar包(官网有下载)，就会报错，所以要在配置文件里面加入

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