spring-mvc.xml文件下配置：<!-- 自动扫描包 -->    <context:component-scan base-package="com.wd">    </context:component-scan>    <!--配置视图解析器 定义JSP文件的位置 -->    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="prefix" value="/"></property>        <property name="suffix" value=".jsp"></property>    </bean>    <!--文件上传配置  -->    <bean id="multipartResolver"    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">          <property name="maxUploadSize" value="10000000" /><!-- 10M -->      </bean>

web.xml:<!--声明一个前端控制器 DispatcherServlet -->    <servlet>        <servlet-name>spring</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <!--表示启动容器时初始化该Servlet -->        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>spring</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>    <!-- spring Web MVC框架提供了org.springframework.web.filter.CharacterEncodingFilter         用于解决POST方式造成的中文乱码问题 -->    <filter>        <filter-name>encodingFilter</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>        <init-param>            <param-name>forceEncoding</param-name>            <param-value>true</param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>encodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>

**controller层代码如下：**

package com.wd.controllers;import java.io.File;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import javassist.bytecode.Descriptor.Iterator;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.multipart.MultipartFile;import org.springframework.web.multipart.MultipartHttpServletRequest;import org.springframework.web.multipart.commons.CommonsMultipartResolver;@Controllerpublic class UpLoadFile {    @RequestMapping(value = "upload2", method = RequestMethod.POST)    public String upLoad2(HttpServletRequest request,            HttpServletResponse response) throws IllegalStateException,            IOException {        // 解析器解析request的上下文        CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(                request.getSession().getServletContext());        // 先判断request中是否包涵multipart类型的数据，        if (multipartResolver.isMultipart(request)) {            // 再将request中的数据转化成multipart类型的数据            MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;            java.util.Iterator<String> iter = multiRequest.getFileNames();            while (iter.hasNext()) {                MultipartFile file = multiRequest.getFile((String) iter.next());                if (file != null) {                    String fileName = file.getOriginalFilename();                    System.out.println(fileName);                    String path = "E:/MyeclipseWorkSpace/springmvc/WebRoot/file/" + fileName;                    File localFile = new File(path);                    // 写文件到本地                    file.transferTo(localFile);                }            }        }        return "result";    }}

WebRoot根目录下index.jsp页面代码：<form action="upload2" method="post" enctype="multipart/form-data"><input type="file" name="file" /> <input type="submit" /></form>

WebRoot根目录下 result.jsp 代码如下

<body>    <body>  <h1>上传成功！</h1>  </body></body>
