他のアプリケーションから呼び出すと完全に動作する残りの Web サービスがありますが、Junit テスターから呼び出すと失敗します。私は過去数時間で多くのことを読みましたが、正しく理解している場合、件名のエラーは2つの考えられる理由で発生しています.1-MockMvcを使用するとJNDIが無視され、2-クラスパスに必要なjarがありません. jar については、他のアプリケーションから呼び出されたときに正しく実行されるため、原因ではないと思います。jndi については、Web サービスが他のアプリケーションから呼び出されたときにコンテナーがデータソースを提供できるのに、モック テスターから呼び出されたときに失敗する理由がよくわかりません。それについて私が見つけた最も近い質問は、モックされた JNDI データソースを Spring でテストする方法です。. このスレッドでは、最後のコメントで良い解決策が得られたようですが、主に「jee:jndi-lookup」を使用した jndi ファイル定義がないため、実装できませんでした。簡単に言うと、残りの Web サービスはメソッドを公開するコントローラーであり、このメソッド内には接続を取得する場所があります。コントローラーを超えるものはすべて、変更することはできません。MockMvc を使用してこの残りの Web サービスをテストするにはどうすればよいですか? レスト サービスがモック テスターから呼び出されたときにロックアップが機能しないのはなぜですか? 「ic.lookup("java:comp/env/jdbc/MHE")」を実行するために、test-mvc-dispatcher-servlet.xml に構成を追加する方法はありますか?

//接続はこのメソッドから提供され、変更できません

public Connection getConnection()throws Exception{
              try{
                     InitialContext ic = new InitialContext();
                     DataSource ds = (DataSource) ic.lookup("java:comp/env/jdbc/MHE"); //the error happens here

// Web サービスを休止

コントローラーはテスト可能に設計されていません。依存関係Mhe_Handlerは method のローカル変数としてインスタンス化されるgetFirstため、単体テストでモックアウトする方法はありません。1 つの解決策は、それをプライベート フィールドとして抽出し、自動配線することです。これは、依存性注入の最も重要な利点の 1 つです。

class Controller {

    //inject real Mhe_Handler backed by jndi datasource in production
    //while inject mockups in unit test
    @Autowired private Mhe_Handler mhe_Handler;

    public LogDisplay getFirst() { 
        //inject dependency instead of hard-wire it
        mhe_Handler.getConnection()

    }

}
