String mobile = request.getParameter("SrcAddr");

 mobile = java.net.URLDecoder.decode(mobile,"UTF-8");
 DestAddr = java.net.URLDecoder.decode(DestAddr,"UTF-8");
 Msg = java.net.URLDecoder.decode(Msg,"UTF-8");
 linkid = java.net.URLDecoder.decode(linkid,"UTF-8");htpp传过来的参数也没有%之类的字符,请问下高手怎么解决，谢谢!警告: Parameters: Character decoding failed. Parameter skipped.
