Java Web servlet uses request forwarding garbled characters.

Java Web servlet uses request forwarding garbled characters.

There are many methods for Garbled text. It is not easy to think of here.

* Make sure that your page is accessed normally independently. When the servlet request is forwarded, PrintWriter out = response. getWriter () is abnormal and does not work properly.

 

The solution is to add

Response. setCharacterEncoding ("UTF-8 ");
Response. setContentType ("text/html; charset = UTF-8 ");
