こんにちは、Spring MVC と webflow 2.4 の最新バージョンを使用しています。機能させるためにすべての手順を実行しましたが、このエラーが発生し続けます...

誰かが私を助けることができますか？

Spring 4.2.4 リリースは、webflow の 2.4.2 リリースとタイル 2.2.2 の依存関係 (tiles-extras、tiles-jsp、tiles-servlet) とうまく連携します。

<webflow-config:flow-registry id="flowRegistry" base-path="/WEB-INF/flows">
    <webflow-config:flow-location path="sales-flow.xml" id="message" />
</webflow-config:flow-registry>

<webflow-config:flow-executor id="flowExecutor" flow-registry="flowRegistry" />

<bean id="flowHandlerAdaptor"
    class="org.springframework.webflow.mvc.servlet.FlowHandlerAdapter">
    <property name="flowExecutor" ref="flowExecutor" />
</bean>

<bean id="flowHandlerMapping"

    <property name="order" value="0" />

例外の根本的な原因は「ネストされた例外は java.lang.NoSuchMethodError: org.springframework.util.ClassUtils.isPresent(Ljava/lang/String;)Z です」

互換性のないバージョンの問題のようです。

すべての Spring フレームワーク アーティファクトのバージョンを確認してください。

Web Flow と Spring 4.0 でまだこの問題が発生している場合は、Web Flow のスナップショット ビルド、つまり 2.4.0.BUILD-SNAPSHOT を使用してビルドする必要があります。

Githubの SWF-1600と変更の詳細を参照してください
