Question

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

使用逆向工程从db模式创建持久性实体[ NB：这是工作中的模式我无法更改]

选择basic_auth_accounts列表时获取异常org.hibernate.TypeMismatchException：为类ebusiness.weblogic.model.UserAccounts提供了错误类型的id。预期：类ebusiness.weblogic.model.UserAccountsId，得到了类ebusiness.weblogic.model.BasicAuthAccountsId

basic_auth_accounts和user_accounts都具有复合主键和一对一关系。有什么线索在这做什么？这对我来说非常重要。在网上找不到任何实质性的解决方案，有人说要创建一个hibernate已经完成的ID类，有些人说没有一对一的关系。

请帮助我!!

Answer 1

只是为了跟进在线观看/研究：

从我可以看到我有两个表basic_auth_accounts和user_accounts使用相同的复合键realmTypeId，realmQualifier和accountId。两个实体都具有可嵌入的类，这些列具有这些列和一对一的关系。

我使用了hibernate工具从DB模式生成这些实体，我无法改变！

我想知道我是否为两个实体使用了相同的嵌入类，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？
