Spring/MyBatis JDBC接続が拒否されました

Question

問題が何であるか分かりません。同じバージョンのTomcat（9）とjdk（1.8.0_121）の2つの異なるマシン（デスクトップとテストサーバー）に同じWARファイルを展開しました。私のデスクトップ（Windows 10 x64）でも動作しますが、テストサーバー（Ubuntu 16.04）ではこのエラーが発生します。

私はデータベースサーバにpingしました。私はそれが到達可能であることを知っています。私は同じデータベースにアクセスし、接続に問題はなかった別のプロジェクトの戦争も行った。

この問題の原因は何ですか？

私に含めたい他の設定ファイルがあるかどうか教えてください。私はエラーの原因を突き止めることができないので、何が関係しているのか分からなかった。

よろしくお願いいたします。

Answer 1

私の問題を解決するために、私はpom.xmlファイル内のすべての依存関係を取り除いて動作させました。 。私は、エラーを探して、その後、後ろに各依存関係を追加し、毎回私のプロジェクトを構築し

私は依存性が欠落していたが判明していない：

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-aspects</artifactId> 
    <version>${spring.version}</version> 
</dependency>
