request.getInputStream()乱码问题解决方案（未解决）

request.getInputStream()乱码问题解决方案

学习request和response时候遇到乱码问题，设置request.setCharacterEncoding(“UTF-8”)也不管用。

源代码：

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		request.setCharacterEncoding("UTF-8");
		ServletInputStream sis = request.getInputStream();
		int len = 0;
		byte[] b = new byte[1024];
		while((len = sis.read(b))!=-1) {
			System.out.println(new String(b,0,len));
		}
		sis.close();
	}

结果依然乱码:

username=tom&pwd=222&sex=%E7%94%B7&hobby=%E7%AF%AE%E7%90%83&city=bj

根据网上资料，
改成如下代码：

request.setCharacterEncoding("UTF-8");
StringBuilder buffer = new StringBuilder();
BufferedReader reader = null;
reader = new BufferedReader(new InputStreamReader
		(request.getInputStream(), "UTF-8"));
String line = null;
while ((line = reader.readLine()) != null) {
	buffer.append(line);
}
reader.close();
System.out.println(buffer);

结果依然不行。。。

先做记录，以后再来探究，也请大牛赐教。（抱拳了
