org.hibernate.exception.ConstraintViolationException：ステートメントを実行できませんでした

つまり、これが当てはまります。struts2とhibernateを使用してWebアプリケーションを作成しています。ユーザーが自分のパスワードを変更できるパスワード変更ページを作成しています。しかし、「org.hibernate.exception.ConstraintViolationException: could not execute statement "..以下は私のコードとスタックトレースです。

エラーは明らかです。パスワード（古いまたは新しい）がアクションPOJOに設定されていません。したがって、[〜＃〜] null [〜＃〜]を取得していますが、これはDBに挿入できないようです（null以外の制約の場合）あなたのDB列）。

パスワードタグの名前がPOJOの名前と一致しません。これにより、パラメーターインターセプターとモデル駆動型インターセプターがPOJOを埋めることができます。 （そうでなければ、ストラットがどのフィールドをどのプロパティに配置する必要があるかを突くことができます）

したがって、タグを次のように変更します（他のタグにも変更します）。

 <s:password name="oldpwd" label="Old Password"/>
 <s:password name="newpwd" label="New Password"/>

以下を参照してください。

https://struts.Apache.org/docs/parameters-interceptor.html

https://struts.Apache.org/docs/model-driven.html

また、参照してください ModelDrivenインターフェイスはstruts2でセキュリティエクスプロットを引き起こしますか？
