【问题描述】：
我将我的应用程序（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 只提供 Oracle12cDialect，不提供 JPA 2.0，而是提供 (hibernate-jpa-2.1-api-1.0.0.Final.jar)
V3.5 到 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：
Caused by: java.lang.ClassCastException: com.ibm.websphere.persistence.PersistenceProviderImpl incompatible with javax.persistence.spi.PersistenceProvider

at org.hibernate.validator.internal.engine.ValidatorImpl.isValidationRequired(ValidatorImpl.java:1221) ~[hibernate-validator-4.3.0.Final.jar:4.3.0.Final
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，则会产生以下问题，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，那么只需要使用Oracle10gDialect。
hibernate 和 webSphere 成员有什么想法吗？
【问题讨论】：

为什么与您使用 Oracle12cDialect 相关？
