java - 使用 Java 配置的 Spring Hibernate JPA - 抽象方法错误

标签 java spring hibernate jpa

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。
