Answer 1

あなたをデプロイするデフォルトでは、Tomcatに1つのアプリケーションしかデプロイされていない場合、コンテキストルートは '/'になります。あなたは具体的には、/desi、あなたはあなたが

<context:component-scan base-package="com.theka.desi.Controllers" /> 

を使用しているSpring構成ファイルで​​

Answer 2

を使用する必要がありますされていることを述べていない限り、それはコントローラが存在するパッケージ名ですか？いいえの場合は、実際のパッケージに変更します。

次にコントローラクラスに@Controllerという注釈を付ける必要があります。この場合、Springは要求されたURLをマップするのに必要な他の注釈を使用できません。http://localhost:8080/desi/
