休眠插入問題

Question

我有兩個實體：PS_PUBLICATION和PS_PUBLICATION_PROPERTIES

PS_PUBLICATION有PS_PUBLICATION_PROPERTIES

在日誌中插入看起來不錯清單，但最後我得到一個錯誤

insert into PS_PUBLICATION (CREATION_DATE, message, FK_SUBJECTAREA_ID, status, subject, UPDATE_DATE, id) values (?, ?, ?, ?, ?, ?, ?) 

binding '2011-07-06 10:36:43' to parameter: 1 

binding 'dc8ca7f0-9d8d-11e0-89b1-00212834363a' to parameter: 3 

binding 'PUBLISHED' to parameter: 4 

binding 'publication 2' to parameter: 5 

binding '2011-07-06 10:36:43' to parameter: 6 

binding '13d6df10-a7ab-11e0-ac48-00212834ce10' to parameter: 7 

insert into PS_PUBLICATION_PROPERTIES (PROP_VALUE, PROP_KEY, FK_PUBLICATION_ID) values (?, ?, ?) 

binding 'close' to parameter: 1 

binding 'CALL-CATEGORY-OPEN' to parameter: 2 

binding '13d6df10-a7ab-11e0-ac48-00212834ce10' to parameter: 3

在插入everythign看起來很好！

任何想法可能會導致這種情況？

謝謝！

Answer 1

org.hibernate.exception.ConstraintViolationException：

Implementation of JDBCException indicating that the requested DML operation resulted in a violation of a defined integrity constraint.

仔細檢查，如果你想插入不違反數據庫約束的數據。看起來數據庫對這些值不滿意。

（如果你捕獲了異常，請撥打ex.getConstraintName()，應該讓更多的細節。）

沒有注意到，在約束名是問題;）你會發現，約束的定義數據庫。詢問你的oracle實例，它會告訴你，哪個表以及哪個插入引起了麻煩。

Error: ORA-02291: integrity constraint violated - parent key not found

Cause: You tried to reference a table using a unique or primary key, but the columns that you listed did not match the primary key, or a primary key does not exist for this table.

您提供兩個UUID的外鍵 - 其中一人是不是在一些其他表的主鍵。或者至少 - 不被oracle認定爲主鍵。
