附件中是以前的servlet学习笔记，下面来补充学习一个servlet中request.getInputStream()的个人认识(可能不对，还请指教)
@RequestMapping(value = "message", method = RequestMethod.POST)
public void request(HttpServletRequest request, HttpServletResponse response) {
try {
// 接收密文
InputStream is = request.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is, "utf-8"));
String line = null;
StringBuilder buff = new StringBuilder();
while (null != (line = br.readLine())) {
buff.append(line);
}
is.close();
br.close();
String ciphertext = buff.toString();
if (null == ciphertext || ciphertext.equals("")) {
throw new Exception("-0002");
}
// 解密密文
//MessageModel msgModel = ClienUtils.decoder(ciphertext, PlatformKeys.platformPriKey);
//此段简单描述输入流
InputStream is = request.getInputStream();
InputStreamReader ir = new InputStreamReader(is,"utf-8");
BufferReader br = new BufferReader(ir);
String str = null;
while(null !=(str = br.readLine()))
{
System.out.println(str);
}
-------------------------------------------------------------------------------------------------------------------
//此段简单描述OutputStream输出流
OutputStream ou = response.getOutputStream();
OutputStreamWriter ow = new OutputStreamWriter(ou,"utf-8");
ow.write(str)
还有一种输出流就是PrintWriter(直接向response管道写数据，通常用于ajax异步请求这里就不说它了)
