私はSpring MVCには新しく、チュートリアルでは基本的な困難を感じました。しかし、私が1つのJSPページで複数のフォームでそれを実行しようとしたとき、それは動作しません。人体測定データフォームの「保存」ボタンをクリックするたびに、「vitalsigns」モデル属性の不正な例外エラーが表示されます。バイタルサインフォームの「保存」ボタンをクリックするたびに、「anthropometricdata」モデル属性の不正な例外エラーが表示されます。私は正しいリクエストマッピングがあると、なぜ春が混乱しているのか分からない。jspページ内の複数のフォームが混乱する原因となるのはなぜですか？
私はすべてのModelAttributesで（ "nameofmodelattribute"）を追加しようとしましたが、それでも助けにはなりませんでした。
私は他のフォームを削除し、人体測定データフォームだけを残しても機能しますが、私はこれがどう起こっているのか分からないようです。
これは示して完全なエラーです：

スタックトレースとエラーメッセージのペーストビンはありません。質問は自己完結型でなければなりません。私は今回はそれを修正した。 –
私はお詫び申し上げます。私はそれがもっと良いと思った。それを変更していただきありがとうございます！ –
ok！フォームからデータを取得するのに 'POST'を使用しています。データをバインドするには' GET'ですか？ – emotionlessbananas
