フォームにフィールドがあり、ユーザークラスにバインドされています。フォームには、このフィールドがあります

<tr>
    <td>AcceptTerms:</td>
    <td><form:checkbox path="acceptTerms"/><td>
</tr>

しかし、フォームを送信した瞬間にエラーが発生します

クライアントから送信された要求が構文的に正しくありませんでした。

私はfirebugでそれを検査し、これを得ました

Parameters   application/x-www-form-urlencoded
_acceptTerms    on
email   ZX
password    ZXZX
rol 2
username    ZxZ
Fuente
username=ZxZ&password=ZXZX&email=ZX&rol=2&_acceptTerms=on

_acceptTerms は、チェックボックスの非表示の値であり、spring tag のデフォルトであると想定しています<form:checkbox>。

これにより、3 つの質問が発生します。このフィールド (_acceptTerms) は、フォームの送信を混乱させますか? _acceptTerms が常に on に設定されているのはなぜですか? このフィールドが実際にフォームを台無しにする場合、どうすればそれを取り除くことができますか、またはどのように処理する必要がありますか? ユーザーモデルに追加しますか?

前もって感謝します

  1. form:checkbox を削除した場合にフォーム送信が機能するかどうかを確認して、実際にこのチェックボックスが問題の原因であることを確認しましたか?
  2. サーバーのデバッグ ログを共有できますか
  3. @requestMapping 値を含むこのフォーム送信を処理しているコントローラー メソッドも共有します

ロールをカテゴリに変換するカスタム バインダーを追加できます カスタム プロパティ エディターを作成します

public class CategoryEditor extends PropertyEditorSupport {

@Override

public void setAsText(String text) {

Category cat = new Category ();

//set rol vlaue in cat

setValue(cat);

}

コントローラーで次のメソッドを使用します

 @InitBinder

    public void initBinderAll(WebDataBinder binder) {

    binder.registerCustomEditor(Category .class,  new CategoryEditor ()); }
