Solution: Encode the Chinese parameter twice before passing the parameter. After obtaining the parameter on the jsp page, decode the Chinese parameter once. The Chinese parameter will not become garbled!
Example:Copy codeThe Code is as follows: <% @ page language = "java" contentType = "text/html; charset = UTF-8"
PageEncoding = "UTF-8" %>
<% @ Page import = "java.net. *" %>
<%
String str0 = "";
String str1 = "";
If (request. getParameter ("param0 ")! = Null ){
Str0 = request. getParameter ("param0"); // get Chinese parameters directly
}
Try {
If (request. getParameter ("param1 ")! = Null ){
Str1 = URLDecoder. decode (request. getParameter ("param1"), "UTF-8"); // decodes Chinese Parameters
}
} Catch (Exception e ){
E. printStackTrace ();
}
