SSM商城系统开发笔记-问题01-通配符的匹配很全面, 但无法找到元素 'mvc:annotation-driven' 的声明。

配置搭建完后进行Post请求测试时报错：

Caused by: org.xml.sax.SAXParseException; lineNumber: 14; columnNumber: 29; cvc-complex-type.2.4.c: 通配符的匹配很全面, 但无法找到元素 'mvc:annotation-driven' 的声明。

查看springmvc配置文件 spring-web.xml如下，发现声明mvc了但没有配置

<?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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

加上配置后

<?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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
