 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:

SLF4J: Defaulting to no-operation (NOP) logger implementation

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。

以上是关于hibernate 错误:org.hibernate.HibernateException: Unable to get the default Bean Validation factory(示例代的主要内容,如果未能解决你的问题,请参考以下文章

Hibernate卡住,然后报错java.sql.SQLException: Unknown system variable 'language'异常

如果 mysql 不存在 Hibernate 4 和 spring 4,则不会自动创建模式

jpa_缓存

当没有 Internet 连接时,Hibernate 给出错误错误,因为“当 'hibernate.dialect' 未设置时,访问 DialectResolutionInfo 不能为空”

学习hibernate出现错误--之二(方言)

从 Hibernate3 升级到 Hibernate5 时出现错误
