环境：JDK 1.6、JEE5 Hibernate Core 3.3.1.GA、Hibernate Annotations 3.4.0.GA DB:Informix

使用逆向工程从 db 模式创建我的持久性实体 [注意：这是我无法更改的工作模式]

选择 basic_auth_accounts org.hibernate.TypeMismatchException 列表时出现异常：为类 ebusiness.weblogic.model.UserAccounts 提供了错误类型的 id。预期：类 ebusiness.weblogic.model.UserAccountsId，得到类 ebusiness.weblogic.model.BasicAuthAccountsId

basic_auth_accounts 和 user_accounts 都具有复合主键和一对一关系。任何线索在这里做什么？这是非常重要的，我让它工作。在网上找不到任何实质性的解决方案，有人说创建一个hibernate已经完成的ID类，有人说没有一对一的关系。

请帮我！！

只是为了跟进在线查找/研究：

据我所知，我有两个表 basic_auth_accounts 和 user_accounts，它们使用相同的复合键 realmTypeId、realmQualifier 和 accountId。两个实体都有带有这些列和一对一关系的可嵌入类。

我使用休眠工具从我无法更改的数据库模式生成这些实体！

我想知道我是否对两个实体使用了相同的可嵌入类，例如将 BasicAuthAccountsId 重命名为更通用的名称，删除 UserAccountsId 并且两个实体都使用相同的 @EmbeddedId 类？
