Spring v3 找不到元素“mvc:resources"的声明 [英] Spring v3 no declaration can be found for element 'mvc:resources'

问题描述

Tomcat: v6

Spring 工具套件:v2.7.2

Spring Tools Suite: v2.7.2

Spring 框架:spring-webmvc-3.0.5

Spring Framework: spring-webmvc-3.0.5

      <mvc:annotation-driven />

      <mvc:resources mapping="/resources/**" location="/resources" />

      <context:component-scan base-package="com.app.mvc" />

 </beans>

web.xml 部分代码

<servlet-mapping>
    <servlet-name>duckapp</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

Servlet 目的

web.xml 将所有 url 映射到 servlet，mvc:resources 映射静态文件除外.

Servlet Purpose

web.xml maps all urls to the servlet with the exception of mvc:resources mapping static files.

• cvc-complex-type.2.4.c:匹配的通配符是严格的，但找不到元素mvc:annotation-driven"的声明.app-servlet.xml/app/www/WEB-INF

• cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'mvc:annotation-driven'. app-servlet.xml /app/www/WEB-INF

cvc-complex-type.2.4.c:匹配的通配符是严格的，但找不到元素mvc:resources"的声明.app-servlet.xml/app/www/WEB-INF

cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'mvc:resources'. app-servlet.xml /app/www/WEB-INF

• http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd 不包含元素资源

如果替换为 http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd 仍然无法工作，并且根据 spring 3.05 的 jar 文件可能无法工作

If replaced by http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd still doesn't work and may not be working according to jar files of spring 3.05

mvc:resources 出现在 spring v3.0.4，但没有新的 xsd

mvc:resources appeared in spring v3.0.4, but has no new xsd

如何修复编译错误以使 mvc:resources 正常工作?

How can I fix the compile errors to get mvc:resources working correctly?

我已经为此挖掘了大约 2 个小时，还没有可靠的答案......

I've been digging around 2 hours for this, no solid answer yet...

推荐答案

在你的 spring 上下文中，xml mvc 命名空间 url 应该与 schemaLocation 中的 url 匹配.像这样:

In your spring context xml mvc namespace url should match url in schemaLocation. Something like this:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
         http://www.springframework.org/schema/mvc
         http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

这是一个标准的 XML 命名空间声明.命名空间 url 是一种唯一的 id，然后映射到 xsi:schemaLocation 中的实际模式位置.

This is a standard XML namespace declaration. The namespace url is sort of an unique id, which is then mapped to the actual schema location in xsi:schemaLocation.
