更新時に@NotNull検証をスキップ

Question

@NotNullまたは@NotEmptyをスキップする方法はありますか？JpaRepository.saveを呼び出すときにセッターメソッドが呼び出されなかった（したがってnull値がある）フィールドの検証はありますか？ 。

：これらのフィールドから @NotNull注釈が JpaRepository.save EntityManager.mergeのように振る舞うので、私はこれらのために @NotNull検証がでキックしないことが予想作るの削除

ここでは上げ検証例外の最初の行です

Answer 1

オブジェクトの主キーがnullの場合、つまりオブジェクトがまだ永続的でない場合は、nullでないかどうかをチェックする独自の@NotNullOnFirstSave検証制約を記述できます。

はhttps://docs.jboss.org/hibernate/validator/5.0/reference/en-US/html/validator-customconstraints.html#validator-customconstraints-constraintannotation

あなたは、これが解決策になることができると思いますか？

:)

Answer 2

@NotNullは、JSR 303 Bean検証アノテーションです。データベースの制約自体とは何の関係もありません。ただし、HibernateはJSR 303のリファレンス実装であるため、これらの制約をインテリジェントに拾い上げ、データベース制約に変換します。 @Column（nullable = false）は、NULLを宣言するJPAの方法です。 Confusion: @NotNull vs @Column(nullable = false)

JPA @Column（nullable = false）アノテーションに加えて、コード内のヌルも確認する必要があります。
