//1）避免中文不能保存的问题，进行URL编码
//userName 是请求行
String sUserName= URLEncoder.encode(userName,"utf-8");
//2）
request.setCharacterEncoding("utf-8");
//3)
response.setContentType("text/html;charset=utf-8");
//4)
String name= req.getParameter("name");
new String(name.getBytes("iso8859-1"),"utf-8");
//5)
byte[] na= name.getBytes("iso8859-1");
String me= new String(na,"UTF-8");
