java - 我想启用矩阵变量，但它显示了消息

Question

"<mvc:annotation-driven enable-matrix-variables="true"/>    
   <context:component-scan base-package="Controllers" />"

它给我以下错误消息:

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 18 in XML document from ServletContext resource [/WEB-INF/appDispatcher-servlet.xml] is invalid;
nested exception is org.xml.sax.SAXParseException; lineNumber: 18; columnNumber: 59; cvc-complex-type.3.2.2: Attribute 'enable-matrix-variables' is not allowed to appear in element 'mvc:annotation-driven'.

Answer 1

我可以确认 Spring 3.2 下正确的写法是 <mvc:annotation-driven enableMatrixVariables="true" >

这里是 Spring Framework 3.2.4 的工作 xml 文件的摘录

    <mvc:annotation-driven enableMatrixVariables="true" >

注意对 3.2 模式的引用
