春のデータ "行の列が長すぎます"

Question

私のデータベースには3つのテーブルがあります。​​。私のApplication.javaは正しい順序でデータファイルを解析するので、テーブル上では次のテーブルに役立ちます。私の問題は、SecondaryFoodDescriptionクラスのdatabankIDフィールドを設定するときに、Data truncation: Data too long for column 'food' at row 1が得られるということです。私は同じrepository.saveメソッドを使って、クラス内のfoodGroupフィールドに値を設定するので、これは驚くべきことです（少なくとも私にとって）。 Food。

編集：通常、Data truncation: Data too long for column 'foodid' at row 1のようなエラーは、私が挿入しようとしているものがフィールドには大きすぎることを意味します。しかし、エンティティを挿入しようとしています。どのように私のエンティティは大きすぎることができますか？

誰でも私が間違っていることを発見できますか？

Answer 1

@OneToOne/@OneToManyの注釈を付ける必要があります。そうしないと、完全なオブジェクトがシリアル化され、BLOBとして永続化されます。 BLOBサイズが大きい場合、Data Truncationエラーが発生します。

Answer 2

SecondaryFoodDescriptionエンティティの@OneToOneアノテーションをフィールドに追加することで "解決済み" foodエンティティです。

これは不満足な回答です。 Foodエンティティには、エンティティFoodGroupの注釈なしフィールドがあります。そのフィールドは「列を長く」エラーを生成しません。
