ModelMapやModelのような他のものを追加する場合、私のコントローラメソッドでRedirectAttributesを使用しているときは、何のエラーも与えない。どうして？java.lang.IllegalArgumentExceptionが発生しました：Spring MVCで "RedirectAttributes"を使用した場合の引数タイプの不一致エラー
解決策のネットを確認しましたが、何も見つかりませんでした。
java.lang.IllegalArgumentExceptionが：引数の型の不一致 sun.reflect.NativeMethodAccessorImpl.invoke0（ネイティブメソッド）春バージョンは何
