SpringMVC同样使用了apache的文件上传组件。所以需要引入以下包：

apache-commons-fileupload.jar

apache-commons-io.jar

在springAnnotation-servlet.xml中配置

1 
     2     
     
      3         
      
      4         
      
      5         
      
      6     
     

控制器：

1 package com.cy.springannotation.controller; 2  3 import java.io.File; 4  5 import javax.servlet.http.HttpServletRequest; 6  7 import org.apache.log4j.Logger; 8 import org.springframework.stereotype.Controller; 9 import org.springframework.web.bind.annotation.RequestMapping;10 import org.springframework.web.bind.annotation.RequestMethod;11 import org.springframework.web.bind.annotation.RequestParam;12 import org.springframework.web.multipart.commons.CommonsMultipartFile;13 14 @Controller15 public class FileUploadController {16     private Logger log = Logger.getLogger(this.getClass());17     18     19     /**20      * CommonsMultipartFile file21      * @param file22      * @return23      */24     @RequestMapping(value="/upload.do",method=RequestMethod.POST)25     public String upload(@RequestParam("fileName") CommonsMultipartFile file,HttpServletRequest req){26         //获取原始文件名27         String fileName = file.getOriginalFilename();28         log.info(fileName);29         String path = req.getSession().getServletContext().getRealPath("upload");30         try {31             file.getFileItem().write(new File(path + File.separator + fileName));32         } catch (Exception e) {33             34             log.error(e);35         }36         return "success";37     }38     39 }

 上传文件页面：

 

1 <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> 2 <% 3 String path = request.getContextPath(); 4 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 5 %> 6  7  8  9   10     11     12     13     14     
     15     
     16     
         17     
     18     
     19     
     22 23   24   25   26    
     
      27         
      
       28             
         29                 
30             
31             
         32                 
33             
34         
35     
     
36     37   38 

 

上传文件就可以了！
