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和Websphere Application Server（8.5.5）支持JPA 2.0。
我看到Hibernate版本> 5仅提供Oracle12cDialect，而不提供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（但是Oracle12cDialect不提供这些版本）
使用hibernate-entitymanager.5.0.7.Final.jar时，在服务电话期间出现以下错误。
错误：

如果我尝试保持应用程序提供的hibernate-jpa-2.1-api-1.0.0.Final.jar范围，则会出现以下问题，因为AttributeConverter类在Websphere JPA 2.0中不可用

如果我使用Hibernate版本支持JPA 2.0，则只需使用Oracle10gDialect。
休眠和webSphere成员有什么想法吗？
答案 0 :(得分：1)
该问题没有解决方案，您只能：
Websphere版本升级到WAS 9.0（当然，这很容易：））Oracle10gDialect，除了特定于版本的详细信息（但我从未在简单的JPA使用中遇到过任何问题），就可以与Oracle 12一起使用。 P.S。有IBM note关于在JPA 2.1上启用WAS 8.5.5的说法，但是老实说，这种努力没有回报（没有更多的容器管理的持久性？谢谢）。
