JPA實體 - org.hibernate.TypeMismatchException

Question

環境： JDK 1.6，JEE5 Hibernate的核心3.3.1.GA，Hibernate註解3.4.0.GA DB：Informix的

使用逆向工程，創造我的堅持從數據庫架構的實體[注：這是在工作模式我不能改變]

獲取例外選擇basic_auth_accounts org.hibernate.TypeMismatchException的列表時：提供了錯誤的類型類ebusiness.weblogic.model的ID。 UserAccounts。預計：類ebusiness.weblogic.model.UserAccountsId，得到了類ebusiness.weblogic.model.BasicAuthAccountsId

兩個basic_auth_accounts和user_accounts具有複合主鍵和一個一對一的關係。 任何線索在這裏做什麼？這是非常重要的，我得到這個工作。在網絡上找不到任何實質性的解決方案，有人說創建一個hibernate已經完成的ID類，有人說沒有一對一的關係。

請幫助我！

Answer 1

只是跟進查找/網上調查：

從我可以看到我有兩個表basic_auth_accounts和使用相同的組合鍵user_accounts realmTypeId ，realmQualifier和accountId。 兩個實體都具有這些列和一對一關係的可嵌入類。

我使用hibernate工具從數據庫模式生成這些實體，我不能改變！

我想知道是否我使用相同的嵌入類的兩個實體，因爲在重命名BasicAuthAccountsId更通用的名稱，刪除UserAccountsId和兩個實體使用相同的@EmbeddedId類？
