java - Hibernate版本支持Oracle12cDialect和JPA 2.0

Question

我将应用程序(Spring + Hibernate + JPA)部署到 Websphere 应用程序服务器，并且应用程序连接到数据库版本 Oracle 12c。

为了支持 Oracle 12c DB，我需要 Oracle12c Dialect 并且 Websphere 应用程序服务器(8.5.5)支持 JPA 2.0。

我看到 Hibernate 版本 > 5 仅提供 Oracle12cDialect，不提供 JPA 2.0，而是提供 (hibernate-jpa-2.1-api-1.0.0.Final.jar)

V3.5至V4.2支持JPA 2.0(但这些版本不适用于Oracle12cDialect)

当我使用 hibernate-entitymanager.5.0.7.Final.jar 时，我在服务调用期间收到以下错误。

错误:

如果我尝试保留应用程序提供的 hibernate-jpa-2.1-api-1.0.0.Final.jar 范围，它会创建以下问题作为 AttributeConverter该类在 Websphere JPA 2.0 中不可用

如果我使用Hibernate版本支持JPA 2.0，那么只需要使用Oracle10gDialect。

hibernate 和 webSphere 成员有什么想法吗？

Answer 1

此问题没有解决方案，您只能:

• 将您的 Websphere 版本升级到 WAS 9.0(当然，这是一个简单的任务:))
• 继续使用 Oracle10gDialect，除了版本特定的详细信息(但我从未在简单的 JPA 使用中遇到任何问题)，它与 配合得很好Oracle 12。

附注有一个IBM note关于在 WAS 8.5.5 上启用 JPA 2.1，但说实话，这种努力没有得到返回(不再有容器管理持久性？不，谢谢)。
