最近在自学Hibernate与Struts2进行集成时，出现了一个错误，错误截图如下：
错误代码如下：

我们先看下hibernate的帮助文档，该文档所在位置：\hibernate-distribution-3.6.10.Final\documentation\manual\zh-CN\html ，可以看中文版本的，有如下描述，截图如下：
这里大意就是在 hibernate.cfg.xml 或者是 persistence.xml 文件下面需要配置 javax.persistence.validation.mode 属性，
于是我们在 hibernate.cfg.xml 文件里添加属性，如下截图所示：
<property name="javax.persistence.validation.mode">none</property>
添加配置后，不报错了。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，如果没有导入hibernate-validator相关的两个jar包(官网有下载)，所以 beanvalitionFactory错误。
hibernate 错误：org.hibernate.HibernateException: Unable to get the default Bean Validation factory
