前提条件

注意：bean的id名不能改变

 

前台页面upload.jsp

 

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%>    
                         
     
      	                上传XML模版文件:
      	                
      	      
      	      
         	
     

 

 

后台Controller代码

//这种是使用传统的form表单提交的，即在前台页面上点击‘上传’按钮上传文件的形式， //而且在form标签上必须指定enctype="multipart/form-data" @RequestMapping(value = "getParamFromFile",method = RequestMethod.POST)	@ResponseBody	public Map
     
       getParamFromFile(@RequestParam("uploadFile") MultipartFile uploadFile,HttpServletRequest request, HttpServletResponse response) {		Map
      
        paramMap = new LinkedHashMap
       
        ();		FileInputStream inputStream = null;				try{			String filename = uploadFile.getName();			String originalFilename = uploadFile.getOriginalFilename();						System.out.println("FileName = " + filename);			System.out.println("originalFilename = " + originalFilename);						inputStream = (FileInputStream) uploadFile.getInputStream();		} catch (IOException e1) {			paramMap.put("message", "上传文件错误");			return paramMap;		}				//String filePath = "E:\\work\\svn\\openeap\\code\\openeap\\src\\main\\webapp\\template\\北京市房屋租赁合同5.xml";    		//paramMap = ImportFile.getParamFromFile(filePath);		paramMap = ImportFile.getParamFromStream(inputStream);                Iterator it = paramMap.entrySet().iterator();        while (it.hasNext()) {         Map.Entry e = (Map.Entry) it.next();         System.out.println("参数 Key: " + e.getKey() + ";  参数 Value: "           + e.getValue());        }                System.out.println("生成的json为：  " + JsonMapper.getInstance().toJson(paramMap));				return paramMap;	}            //jQuery form插件的使用   后台    @RequestMapping(value = "getParamFromFileForAjax",method = RequestMethod.POST)	@ResponseBody	public Map
        
          getParamFromFileForAjax(HttpServletRequest request,String fileName) {		Map
         
           paramMap = new LinkedHashMap
          
           (); FileInputStream inputStream = null; //把Request强转成多部件请求对象 MultipartHttpServletRequest multipartHttpServletRequest = (MultipartHttpServletRequest) request; //根据文件名称获取文件对象 CommonsMultipartFile commonsMultipartFile = (CommonsMultipartFile) multipartHttpServletRequest.getFile(fileName); try{ String filename = commonsMultipartFile.getName(); String originalFilename = commonsMultipartFile.getOriginalFilename(); System.out.println("FileName = " + filename); System.out.println("originalFilename = " + originalFilename); inputStream = (FileInputStream) commonsMultipartFile.getInputStream(); } catch (IOException e1) { paramMap.put("message", "上传文件错误"); return paramMap; } //String filePath = "E:\\work\\svn\\openeap\\code\\openeap\\src\\main\\webapp\\template\\北京市房屋租赁合同5.xml"; //paramMap = ImportFile.getParamFromFile(filePath); paramMap = ImportFile.getParamFromStream(inputStream); Iterator it = paramMap.entrySet().iterator(); while (it.hasNext()) { Map.Entry e = (Map.Entry) it.next(); System.out.println("参数 Key: " + e.getKey() + "; 参数 Value: " + e.getValue()); } System.out.println("生成的json为： " + JsonMapper.getInstance().toJson(paramMap)); return paramMap; }
