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

Question

我第一次尝试将 SWF 集成到 Spring mvc 应用程序中，但出现此错误:

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException
来自 ServletContext 资源 [/WEB-INF/mvc-dispatcher-servlet.xml] 的 XML 文档无效；嵌套异常是 org.xml.sax.SAXParseException；行号:XX；栏目编号:XX； cvc-complex-type.2.4.c: 匹配的通配符是严格的，但找不到元素 'webflow:flow-builder-services' 的声明

这是我的 mvc-dispatcher-servlet.xml 文件(由 web.xml 中的 contextConfigLocation 引用)

我正在使用 spring 3.0.3.RELEASE 和 spring webflow 2.1.1.RELEASE

你有关于这个问题的解释吗？

提前致谢

Answer 1

更改您的 spring beans 架构版本。您使用的是 2.5，但它应该是 3.0。
