Spring Hibernate JPA with Java配置-抽象方法错误

java spring hibernate jpa

Spring Hibernate JPA with Java配置-抽象方法错误,java,spring,hibernate,jpa,Java,Spring,Hibernate,Jpa,由于Hibernate 5.2贬低了Criteria API，我将所有Criteria API代码更改为JPA，但当我尝试运行该程序时，它会给我以下错误： org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [com/vincent/SSHAKB/configurati

我不明白为什么它说的是抽象错误。。。如果我使用CriteriaAPI的旧方法，代码将正常工作（显然需要更改DBConfig.java的实现）

我已经用一些问题搜索了stackoverflow，但我找不到解决方案

编辑：我用堆栈跟踪更新了错误

解决方法：使用最新的jadira和hibernate验证器，不要混淆hibernate 4和hibernate 5之间的版本

您正在为jadira用户类型使用版本3.0.0.CR1。您能试用最新版本的Jadira Usertype Core吗？hibernate 5和jadira用户类型版本存在一些问题。

通过使用最新的jadira用户类型和hivernate验证程序进行修复，不要将hibernate 4和hibernate 5之间的版本混合使用。

发布嵌套异常。堆栈跟踪末尾的一个。说什么的那个AbstractMethodError@NeilStockton我更新了堆栈跟踪，现在已修复
