java - Spring 3 MVC および JSR303 @Valid が機能しない BindingResult haserrors は常に false

Question

Spring 3 MVC と JSR303 でフォームの検証を行っているので、助けが必要です。とにかく、私が働く前でしたが、その後ではありませんでした。JSON 形式の BindingResult でエラーを解析するクラスを作成し、より単純化しました。今私が得るのは、常に false HasErrors getFieldErrors を返すということです 常に空で、エラーは発生しません。

コードをコピーして、手を貸していただけるかどうかを確認します。

前に言ったように、例外が発生しないからではなく、エラーを返すようになりました。手伝ってくれますか？

どうもありがとうございました。
