中文乱码问题

//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");
