通配符的匹配很全面, 但无法找到元素 'mvc:annotation-driven' 的声明

通配符的匹配很全面, 但无法找到元素 ‘mvc:annotation-driven’ 的声明

报错信息:
通配符的匹配很全面, 但无法找到元素 ‘mvc:annotation-driven’ 的声明

报错原因:
在xml文件上方声明了mvc,但没有配置此声明对应的文件信息,正确配置如下:

<?xml version="1.0" encoding="UTF-8"?>    
<beans xmlns="http://www.springframework.org/schema/beans"    
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:tx="http://www.springframework.org/schema/tx"

    xsi:schemaLocation="

        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">    

mvc声明用http://www.springframework.org/schema/mvc/spring-mvc.xsd这个文件来解析,必须给出声明。
