BeanCreationException：創建在ServletContext中定義的名稱爲'/'的bean時出錯

嗨，我正在使用Spring MVC和webflow 2.4的最新版本，我遵循所有步驟以使其工作，但我不斷收到此錯誤...BeanCreationException：創建在ServletContext中定義的名稱爲'/'的bean時出錯

有人可以幫助我嗎？

這是一個祕密，應該有助於閱讀這些貪婪的堆棧痕跡 - 忽略'後的所有內容;嵌套的異常是在每一行中。嵌套的異常包含在'Caused by：'行中的異常之下。這應該可以讓你避免大量無意義的水平滾動來回滾動。 – ArtOfWarfare

現在，如果堆棧跟蹤中的任何地方實際上告訴你需要查看哪些線路，那麼真正有用的將是什麼。據我所知，這些堆棧跟蹤永遠不會告訴你哪一行文件導致問題。 – ArtOfWarfare

異常的根本原因是「嵌套的異常是用java .lang.NoSuchMethodError：org.springframework.util.ClassUtils.isPresent（Ljava/lang/String;）Z「

它似乎是不兼容的版本問題。

請檢查所有彈簧框架工件的版本。

對於Web Flow和Spring 4.0仍然存在此問題的任何人，您需要構建Web Flow的快照構建，例如2.4.0.BUILD-SNAPSHOT。

見SWF-1600和change details on Github

春4.2.4版本與瓷磚的一個Webflow和依賴2.2.2（瓷磚，演員，瓷磚，JSP，瓷磚小服務程序）

<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" 
    class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping"> 
    <property name="flowRegistry" ref="flowRegistry" /> 
    <property name="order" value="0" /> 
</bean>

的2.4.2版本效果很好
