最近Struts 2の入力チェックを勉強して、自分でまとめて、後で自分の学習チェックを振り返って、復習の準備をしているかもしれません.
入力チェックに対して、Struts 2は2つの方式を提供し、1:手書きコードで実現する;2:XML構成に基づく実装.
1:手書きコードで実現.
ActionSupportクラスを継承し、vlidateメソッドを書き換えてデータ検証を行います.あるデータ検証に失敗した場合、addFieldError()またはaddActionError()を呼び出してシステムのFieldErrorに情報を追加する必要があります.検証に失敗した場合、Struts 2はinputというresultという結果ページに自動的に転送されます.失敗情報はinputビューでというラベルで取得できます.これにより、検証が完了します.

ユーザーが入力したフィールドタイプが正しくないことを防止するために、例えば、年齢ユーザーがabcを入力したので、struts 2タイプの変換に失敗したときにユーザーにヒントを与えるファイルを構成します(struts 2タイプの変換は私が書いた学習ノートを見てください)

以上は手動符号化の形式でデータ検証を行ったが,これにも欠点があり,我々は特有の方法を検証する必要がなく,他の方法を検証する必要がない場合がある.
また検証しなければなりません.どうすればいいですか.struts 2は私たちに良い解決策を提供してくれました.
メソッドを手動で書くこのメソッドの署名はvalidate()メソッドと同様です.たとえばabc()メソッドを検証する必要があります.----validateAbc()です.(注意:validate()メソッドは書かないが、execute()メソッドを検証する場合はvalidateExecut()と書きます.)
2:XMLで実現.
xml構成の実装では、xmlプロファイルをactionと同じパッケージに配置し、ルールActionName-validationを命名する必要があります.xml(これはAction全体を検証する)Actionの方法を検証する--』AcitonName-MthodName-validation.xml
