数据都保存到HttpServletRequest中

@Override
    	public boolean insertBook(HttpServletRequest request) {
    		try{
    			//用于封装数据
    			Book book = new Book();
    			
    			//解析请求中的数据
    			MultipartHttpServletRequest mpRequest = (MultipartHttpServletRequest) request;
    			
    			String bookName = mpRequest.getParameter("bookName");
    			float price = Float.parseFloat(mpRequest.getParameter("price"));
    			Integer num = Integer.parseInt(mpRequest.getParameter("num"));
    			String date = mpRequest.getParameter("publishDate");
    			SimpleDateFormat format = new SimpleDateFormat("yyyy-mm-dd");
    			Date publishDate = format.parse(date);
    			
    			//封装数据
    			book.setBookName(bookName);
    			book.setPrice(price);
    			book.setNum(num);
    			book.setPopular(0);
    			book.setPublishDate(publishDate);
    			
    			MultipartFile file = mpRequest.getFile("imageUrl");
    			String path = request.getSession().getServletContext().getRealPath("bookImage");
    			String imageUrl = UploadUtil.uploadFile(file, path);
    			book.setImageUrl(imageUrl);
    			
    			bookMapper.insertBook(book);
    			return true;
    		}catch(Exception e){
    			e.printStackTrace();
    			return false;
    		}
    		//return false;
    	}

解析存放图片的imageUrl

public static String uploadFile(MultipartFile file, String path) throws IOException{
    		//上传文件的真实名称
    		String name = file.getOriginalFilename();
    		//System.out.println(name);
    		//获取后缀名
    		String suffixName = name.substring(name.lastIndexOf("."));
    		//System.out.println(suffixName);
    		//自定义随机数
    		String hash = Integer.toHexString(new Random().nextInt());
    		String fileName = hash + suffixName;
    		//System.out.println(fileName);
    		
    		File tempFile = new File(path, fileName);
    		if(!tempFile.getParentFile().exists()){
    			tempFile.getParentFile().mkdir();
    		}
    		if(tempFile.exists()){
    			tempFile.delete();
    		}
    		tempFile.createNewFile();
    		file.transferTo(tempFile);
    		return tempFile.getName();
    	}
