由于 Hibernate 5.2 弃用了 Criteria API,我将所有 Criteria API 代码更改为 JPA,但是当我尝试运行该程序时,它给出以下错误:

}

我不明白为什么它提示说抽象错误...如果我使用 Criteria API 的旧方法,代码将有效(并且显然需要更改 DBConfig.java 的实现)。

我已经在 stackoverflow 中搜索了一些问题,但找不到解决方案..

编辑:我用堆栈跟踪更新了错误解决:使用最新的jadira和hibernate validator ,不要混淆hibernate 4和hibernate 5之间的版本

最佳答案

您正在使用 3.0.0.CR1 版本作为 jadira 用户类型。您可以尝试使用最新版本的 Jadira Usertype Core 吗? hibernate 5 和 jadira 用户类型版本存在一些问题。

关于java - 使用 Java 配置的 Spring Hibernate JPA - 抽象方法错误,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/39059821/
