Mavenプロジェクトの例外：javax.servlet.ServletException：名前 'dispatcher'を持つサーブレットの名前が 'login'のビューを解決できませんでした

Question

私はMavenとSpringを初めて使用しています。私は、MavenとSpringをベースにした1つのアプリケーションの作業を開始しています。

正常に適用されます。適切に展開しますが、localhost：8080にヒットしたときに何が問題なのか分かりません.500エラーが発生します。

HTTP Status 500 - Could not resolve view with name 'login' in servlet with 

name 'dispatcher' 

type Exception report 

message Could not resolve view with name 'login' in servlet with name 'dispatcher' 

description The server encountered an internal error that prevented it from fulfilling this request.

問題は私のアプリケーションである場合、私は理解できませんでした。解決策を提供してください.. !!

Answer 1

dispatcherサーブレットの設定が複雑です！

あなたはあなたの責任は、リソースを自分で処理するようになり、デフォルトのルートサーブレットをオーバーライドしているあなたの現在の構成では

<servlet> 
    <servlet-name>dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <load-on-startup>1</load-on-startup> 
</servlet> 
<servlet-mapping> 
    <servlet-name>dispatcher</servlet-name> 
    <url-pattern>/</url-pattern> 
</servlet-mapping> 

、次のように設定を行うことで責任を最小限に抑えるようにしてみてください。

また、あなたのURLがあなたのコンテキスト正しいWRTであることを確認してください

http://localhostすなわち：{PORT_NO}/{application_context_name} /ログイン
