Garbled characters occur when JSP passes Chinese parameters through address addresses

Chinese garbled characters have plagued JSP ProgramClerk, I often see this situation during programming;
After a piece of writing experience and absorbing his experience, the situation of "garbled characters in passing Chinese parameters through address addresses in JSP" is summarized as follows;
(1) In tomcat, because the pass by get method in the past, Tomcat will be converted to the original by ISO-8859-1 (Address Bar default) encoding
UTF-8 form, if read by UTF-8, no need to convert;
The response. sendredirect () format is:
Response. sendredirect ("*****. jsp? Message = "+ java.net. urlencode. encode (" Chinese "));
(2) when using the previous method in JBoss, we still cannot obtain the correct Chinese;
You also need to convert the obtained encoding as follows:
String MSG = new string (request. getparameter ("message"). getbytes ("ISO-8859-1"), "UTF-8 ");
Personal guess: the service may not automatically convert the ISO-8859-1 code to the UTF-8 when getting the variable, so we need to convert it manually;
However, I still have some questions. Isn't JBoss embedded with tomcat?

Of course, there are still many solutions to coding problems;
You can find them online.
