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:

查看springmvc配置文件 spring-web.xml如下,发现虽然声明mvc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">

    <!--配置spring mvc-->
    <!--1,开启springmvc注解模式
    a.自动注册DefaultAnnotationHandlerMapping,AnnotationMethodHandlerAdapter
    b.默认提供一系列的功能:数据绑定,数字和日期的format@NumberFormat,@DateTimeFormat
    c:xml,json的默认读写支持-->
    <mvc:annotation-driven/>
    <!-- @ResponseBody注解支持-->
    <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="mappingJackson2HttpMessageConverter"/>
            </list>
        </property>
    </bean>

    <bean id="mappingJackson2HttpMessageConverter"
          class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
                <value>text/json;charset=UTF-8</value>
                <value>application/json;charset=UTF-8</value>
            </list>
        </property>
    </bean>

    <!--2.静态资源默认servlet配置-->
    <!--
        1).加入对静态资源处理:js,gif,png
        2).允许使用 "/" 做整体映射InternalResourceViewResolver
    -->
    <mvc:default-servlet-handler/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!--4:扫描web相关的bean-->
    <context:component-scan base-package="com.boron.controller"/>
</beans>

 

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:context="http://www.springframework.org/schema/context"
