依赖jar：

    	
     
      commons-fileupload
     	
     
      commons-fileupload
     	
     
      1.3.1
     
    

采用fileupload组件进行上传，jsp页面：

    
	
     
		      
       
			        
				领客网linkrmb.com数据上传单			
		       
		       
			        
				用户账户(email)：			
			        
							
		       
		       
			        
				上传文件：			
			        
							
		       
	      
     
	
     		
      		
      	
     
    

对应的控制层的代码：

protected String storeFile(HttpServletRequest request, String baseDir)			throws Exception {		DiskFileItemFactory factory = new DiskFileItemFactory();		ServletFileUpload upload = new ServletFileUpload(factory);		List
    
      items = upload.parseRequest(request);		Iterator
     
       itr = items.iterator();		String file = "common_data_file_";		while (itr.hasNext()) {			FileItem item = (FileItem) itr.next();			if (!item.isFormField()) {				System.out.println("上传文件的大小:" + item.getSize());				System.out.println("上传文件的类型:" + item.getContentType());				System.out.println("上传文件的名称:" + item.getName());				file = file + item.getFieldName();				item.write(new File(baseDir + File.separator + file));				break;			}		}		return file;	}
