Haben Sie Maven für Ihre Anwendung verwendet? Wenn ja, könnten Sie bitte pom.xml hinzufügen .. wenn nicht, würde gerne sehen, welche Gläser Sie in Ihrer Anwendung verwendet haben – asg

ja, siehe Edited: –

Problem scheint mit dem feder web.jar zu sein - wie es gelöst zu werden. Es wird aufgelöst als transitive Abhängigkeit von spring-webflow-2.4.4-Release.jar. (Bitte beachten Sie die linke Seite der angehängten Datei.)

Und aufgelöste Abhängigkeit feder web: 4.3.0.Release (rechte Seite des Bildes). Und dieses Jar enthält nicht die Klasse, für die Sie eine Ausnahme erhalten. Sie können das Glas von here herunterladen und überprüfen Sie es.

Um dieses Problem zu lösen, fügen Sie direkte Abhängigkeit wie folgt:

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

die transitive Abhängigkeit Dies wird außer Kraft gesetzt durch feder Webflow hinzugefügt. Obwohl ich dies lokal nicht versucht habe, sollte dies Ihr Problem lösen.

Es funktioniert. Danke @asg. Du bist toll. : D –
