1. 配置Spring 文件类型解析器

2. 配置单文件上传

2.1.前端上传代码

<%--action前面的"/"  加上表示使用绝对路径,反之为相对路径--%>

2.2 开发Action

@RequestMapping("getFile.do")    public ModelAndView getFile(HttpServletRequest request, @RequestParam("imgCard") MultipartFile multipartFile) throws IOException {        String name = request.getParameter("name");        System.out.println("name = " + name);        //得到文件的名称;        String originalFilename = multipartFile.getOriginalFilename();        //希望存储的目标地址        File file = new File("C:\\Users\\lyuweigh\\Desktop\\"+originalFilename);        multipartFile.transferTo(file);        ModelAndView mv = new ModelAndView();        mv.setViewName("index.jsp");        mv.addObject("demo", "ojbk");        return mv;    }

• MultipartFile ,用来存储对应上传的文件
• @RequestParam("xx") ,接受指定的name名称值

3. 配置多文件上传

3.1.前端上传代码

    
    
     
              
       
                    
文件名称:
                    
               
               
                    
               
               
                    
               
               
                    
               
               
                    
               
               
                    
               
          
     
    

3.2 开发Action

@RequestMapping("getFiles.do")    public ModelAndView getFiles(HttpServletRequest request, @RequestParam("imgCards") CommonsMultipartFile[] files) throws IOException {        String name = request.getParameter("name");        System.out.println("name = " + name);        for (CommonsMultipartFile file : files) {            String originalFilename = file.getOriginalFilename();            file.transferTo(new File("C:\\Users\\lyuweigh\\Desktop\\"+originalFilename));        }        ModelAndView mv = new ModelAndView();        mv.setViewName("index.jsp");        mv.addObject("demo", "ojbks");        return mv;    }
