Question

私はJ2EEのnoob（.Netスタック）であり、基本的なチュートリアルを地面から手に入れようとしています。 Tomcat 8.5を設定してEclipseを使用しています。

私は

applicationContext.xmlを...

...私の設定ファイルは次のようになり

あなたは、あなたのプロジェクトのビルド・パスにロガーの依存関係が欠落しているに春のWebflow推移依存を除外することもできます。これは修正されませんでした

Answer 2

：java.lang.NoClassDefFoundErrorが：ORG/apacheの/コモン/ログ/たLogFactory

エラーが不足している依存関係、コモンズについてですクラスパスにログ記録用のjarがありません。あなたのpom.xmlは

<!-- https://mvnrepository.com/artifact/commons-logging/commons-logging --> 
<dependency> 
    <groupId>commons-logging</groupId> 
    <artifactId>commons-logging</artifactId> 
    <version>1.2</version> 
</dependency> 

を欠落している可能性があり、あなたは「コモンズ・ログ」
