私はJava EEのSpringフレームワークを学んでいます。プロジェクト構造を変更した後、RequestMappingとHibernateが期待どおりに動作しない
最近、データソースとしてバックエンドデータベースをサポートして、安らかなサービスを構築したいと考えています。私はどのように最終的に作業サンプルプロジェクトhereを見つける多くの記事を検索しました。この投稿は素晴らしいと私は彼のコードに従って、実行中のアプリケーションを作った。
しかし、私は5つ以上のモデルと複数の他のインターフェイスがあるので、私は私自身のプロジェクト構造を持っていることにしました。
これは彼のプロジェクト構造です。

アプリケーション（彼と私の両方）と彼のバージョンを確認しましたが、私のものは動作しませんでした。設定/プロパティファイルがありますが、それらはすべて同じで、ファイルパス設定は含まれていません。
これは彼のアプリケーションのためのコンソールの結果です。私はすでにどの部分が私と違っているのか分かっていますが、それを解決する方法はわかりません。申し訳ありませんがログは非常に長いですが、私は違う行についてあなたに教えてくれます。
これらの行は、15:09:58.364から15:09:58.371までの行です。それは私の冬眠は私のDBに私のモデルでテーブルをマップしていないようだ。私はこれらの行がありません。
そして、4行は15:09:59.013で始まります。 URLが正しくマップされていないようです。私はこれらの行がありません。
その他のログはほぼ同じです。

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

私のプロジェクトはhereであると言います。
これは非常に長い説明とエラーレポートの問題です。何か助けと時間をいただきありがとうございます。

こんにちは！今、私は他のすべての* .javaをサブパッケージに入れていますが、それでも動作しません。投稿でプロジェクト構造を設定するために 'Application.java'でアノテーションを使用する方法についてのヒントを教えてください。 – Kulbear
モデル以外のすべてのファイルをデフォルトのパッケージに移動しましたが、今は（彼のプロジェクトのように）動作します。私はまだ複雑な構造でプロジェクトを管理する方法を知りたいですが。どうも！ – Kulbear
デフォルトパッケージ内の 'Application.java'のみを移動し、必要に応じて他の場所はすべて保管してください。 – Mubin
