例外：セッションとデータベース状態を同期させることができませんでした

Question

Webアプリケーションを春と休止状態3.0で開発し、Apache Tomcat 6にデプロイしました。 データをテーブルの1つに挿入しようとすると、 （ 'CAR_ATTRIBUTE'テーブル）。

このエラーは、本番環境でのみ再現可能です。同一のコードが同じDBを指している私のローカル環境で動作しています。 ロガーステートメントを追加しようとしましたが、シーケンスジェネレーターが毎回同じ値、つまり「0」を生成していることがわかりました。 urヘルプを待っています。

返信いただきありがとうございます。はい、例外は明確にその制約に違反していると言います。 CARS.XAK1CAR_ATTRIBUTEはキーが結合されており、一意でなければなりません。私はすべてのデータを（ロガーによって）検証し、この制約に違反する可能性のあるデータを見つけられませんでした。さらに、この制約に違反している場合、同じDBを指している私のローカル環境では機能しません。 これはサーバー固有のものですか？ テーブルのDDLや挿入しようとしているデータなどの詳細を提供できますが、問題を解決するのに役立ちます。 --Santosh

Answer 1

特にあなたがこの保存に何をしているかについての詳細を知らなくても、すべて私に言えることは、答えはあなたが制約のいくつかの並べ替えを違反しているスタックトレースに

unique constraint (CARS.XAK1CAR_ATTRIBUTE) violated 

であるということです。おそらく、あなたが更新しようとしているときに貯蓄していますか？

Answer 2

これは、hibernate cache ....の問題であるようです。単一のキャッシュフラッシュ内では、コレクションを含むオブジェクトを2回更新することはできません。コードの最後にsession.flush（）を追加してみてください...
