直接看代码吧，注释都在里面
首先是web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<description>配置SpringMVC的前端控制器</description>
<servlet-name>upload</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>upload</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<filter>
<description>解决参数传递过程中的乱码问题</description>
<filter-name>CharacterEncodingUTF8</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingUTF8</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
下面是位于//src//applicationContext.xml
1 <?xml version="1.0" encoding="UTF-8"?>

12 <!-- 启动Spring的组件自动扫描机制(Spring会自动扫描base-package指定的包中的类和子包里面类) -->

16 <!-- 启动SpringMVC的注解功能,它会自动注册HandlerMapping、HandlerAdapter、ExceptionResolver的相关实例 -->
17 <mvc:annotation-driven/>
18
19 <!-- 由于web.xml中设置SpringMVC拦截所有请求,所以在读取静态资源文件时就会读不到 -->
20 <!-- 通过此配置即可指定所有请求或引用"/js/**"的资源,都会从"/js/"中查找 -->
21 <mvc:resources mapping="/js/**" location="/js/"/>
22 <mvc:resources mapping="/upload/**" location="/upload/"/>

24 <!-- SpringMVC上传文件时,需配置MultipartResolver处理器 -->
