入れ子になった例外はjava.lang.NoClassDefFoundErrorです：org/springframework/web/context/request/async/AsyncRequestTimeoutException

私はスプリングウェブフローを設定したspring（4）mvcアプリケーションを持っています。フローURL（/ context/pizza/buy）を押すと、この例外が発生します。完全な例外トレース入れ子になった例外はjava.lang.NoClassDefFoundErrorです：org/springframework/web/context/request/async/AsyncRequestTimeoutException

アプリケーションにmavenを使用しましたか？はいの場合は、pom.xmlを追加してください。そうでない場合は、アプリケーションで使用したjarファイルを確認してください。 – asg

はい、編集： –

問題は、ばねweb.jarであると思われる - それは解決なっていますか。 spring-webflow-2.4.4-Release.jarの推移的な依存として解決されています。 4.3.0.Release（画像の右側）：（。添付ファイルの左側を参照してください）

を、解決の依存関係は、ばねウェブです。そして、この瓶にはあなたが例外を受けているクラスは含まれていません。あなたはhereからjarをダウンロードして調べることができます。

次のように直接的な依存関係を追加し、この問題を解決するには、次の

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

これは、ばねのWebflowによって追加推移依存関係をオーバーライドします。私はこれをローカルで試していませんが、これはあなたの問題を解決するはずです。
