找不到元素 'webflow:flow-builder-services' 的声明

Question

我正在尝试首次将SWF集成在Spring MVC应用程序中，但是我遇到了此错误：

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException in XML document from ServletContext resource [/WEB-INF/mvc-dispatcher-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: XX; columnNumber: XX; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'webflow:flow-builder-services'

这是我的MVC-dispatcher-servlet.xml文件（web.xml中的ContextConfiglocation引用）

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:webflow="http://www.springframework.org/schema/webflow-config"

    <property name="suffix">

    </property>
</bean>

我正在使用Spring 3.0.3.Release和Spring WebFlow 2.1.1.Release

您对此问题有解释吗？

预先感谢

Answer 1

更改您的弹簧豆模式版本。您使用的是2.5，但应为3.0。

Answer 2

你是对的！

这是一个不匹配的版本。当我使用SWF 2.1.1.Release

时，我还将春季WebFlow模式版本更改为http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.0.xsd

ps：验证由Maven下载的Spring Jars并将其版本与在模式位置中声明的版本进行比较也很重要。（如果使用了Spring-Webflow 2.1.1，则模式位置必须声明Spring-Webflow-Config-2.0不是Spring-Webflow-Config-2.3，对于其他Spring Jars/schema声明而言）
