java - Spring と GAE : ExceptionInInitializerError

Question

私は今、Spring、GAE、Java 全般に取り組んでいます。Spring 用に作成し、後で GAE サポートを追加した Web アプリを使用しようとしています。私は多くの問題を経験しましたが、今はこれに行き詰まっています。

コンテキストが適切に初期化されていないことに気付きましたが、これは Spring によって直接管理されているため、これを解決する方法がわかりません。どのような情報を提供すればよいかわかりませんので、ここに重要なファイルをいくつか示します。

ここに表示される構成ファイルから。すべてが良さそうです。例外は初期化エラーを示します。プロパティファイルまたはコンストラクターが初期化に失敗した場合に発生することがあります。ここの構成ファイルに基づいて確認できますか?

<resources mapping="/resources/**" location="/resources/" />

設定済みで準備完了?? src の下にプロパティフォルダーがあり、出力ディレクトリにコンパイルされます。

スタックトレースにあるもう 1 つのことは、DefaultListableBeanFactory 例外の初期化の問題です。クラスパスに正しいバージョンの spring Jar ファイルがあるかどうかを確認してください。
