なぜ私のapplicationContext.xmlがDispatcherServletに必要ですか？

Question

のDispatcherServletのみMVC-config設定を管理するための責任がある、とのContextLoaderListenerはapplicationContext.xmlを

これはweb.xmlの私の古い設定だったために責任があるではありません。

、私は次の例外を得ました

この例外は、web.xmlのDispatcherServletにapplicationContext.xmlを追加した後に解決されました。

Answer 1

@Transactionalと思っています。その場合、<tx:annotation-driven />の効果は宣言されているコンテキストに限定されていることに注意してください。

@Transactionalの豆がwebmvc-config.xmlで宣言されている場合は、<tx:annotation-driven />も追加する必要があります。 <tx:annotation-driven />がapplicationContext.xmlにのみ指定されていると、記述した動作が発生する可能性があります。私はそれが自分のコンテキストの持つ各ディスパッチサーブレットに関係していると思います

Answer 2

は、このブログで

http://www.dotkam.com/2008/07/09/spring-web-application-context-visibility/

を見て、私は、私はすべての私をロードするために、リスナーを使用して、このようにいくつかのことをすることによって、この問題を解決しましたディスパッチサーブレットは、コンテキストコンフィギュレーション

を持っていないの不平を言うので、私はそれに定義されていない構成でダミーコンテキストの設定を作成し、この

<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value> 
     /WEB-INF/spring/applicationContext.xml, /WEB-INF/spring/applicationContext-MVC.xml 
    </param-value> 
    </context-param> 

のようなコンテキストファイルは、私がこれをしなければなりませんでした

<init-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value> 
     /WEB-INF/spring/dummy-config.xml  
     </param-value> 
    </init-param>
