forms - return new ModelAndView リダイレクトが何らかの理由で機能しない

Question

私はSpring MVCフレームワークに本当に慣れていないので、今すぐ助けが必要です。

何らかの理由で、リダイレクトが機能せず、HTTP ステータス 400 が表示され、コンソールにエラーが表示されないため、デバッグが非常に困難です。

シナリオ: 2 つのフォームがあります。最初のフォームは適切に保存され、2 番目のフォームにリダイレクトされますが、コードを繰り返して 3 番目のフォームに渡すと、http 400 エラーが発生します。最初のフォームで使用したものを複製したと確信しています。

意見：
