小巧，但在中文语境下，还是要注意的。

以下是关键语句，注意转码的先后顺序，这源于GET是HTTP服务器处理，而POST是WEB容器处理：

String name = request.getParameter("nameGet");

name = new String(name.getBytes("ISO-8859-1"), "gb2312");

================================

request.setCharacterEncoding("gb2312");

String name = request.getParameter("namePost");
