Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Unable t

spring与hibernate整合然后出现如下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Unable to get the default Bean Validation factory
Caused by: org.hibernate.HibernateException: Unable to get the default Bean Validation factory
Caused by: java.lang.reflect.InvocationTargetException
Caused by: org.hibernate.HibernateException: Unable to build the default ValidatorFactory
Caused by: javax.validation.ValidationException: Unable to instantiate Configuration.
Caused by: java.lang.NullPointerException

分析错误原因就是编译器无法识别和找到bean的validate包，但是，这个包确实存在的，然后根据查询发现hibernate有一个属性javax.persistence.validation.mode，这个属性默认是auto的，但是这样的话，编译器就无法识别了，所以需要我们手动设置一下，所以找到你的hibernate.cfg.xml文件，将这个属性加入进去。

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

加入后上述问题全部没有了，写的测试类，就好使了。

希望犯愁的小伙伴可以解决这个问题，多谢您的支持，没事请点赞！！！
