Get request parameter is Chinese is garbled problem

Request.setcharacterencoding ("UTF-8"); This is set in Java code to change the request encoding to Utf-8, but only valid for post
String path= request.getparameter ("Documentpath"); Get the Chinese parameters passed in.
String method = Request.getmethod (); Get the submission method
if (method!=null && "get". Equals (method)) {//If it is a GET way
Path= New String (Path.getbytes ("iso8859-1"), "UTF-8"); (The UTF-8 here depends on the encoding of the JSP page) so the path obtained will not be garbled.
