文件上传对servlet的要求

 

---

request.getParamter(String name)方法不能再使用了

 

---

需要使用request.getInputStream()获取输入流对象然后在进行读取数据

解析数据

  ServletInputStream inputStream = request.getInputStream() ;

                   byte[] bytes = new byte[1024] ;

                   int len = 0 ;

                   while((len = inputStream.read(bytes)) != -1) {

                            System.out.print(new String(bytes , 0 , len));

 }
