解決方案：在傳遞參數前將中文參數進行兩次編碼，jsp頁面擷取參數後對中文參數進行一次解碼，中文參數就不會變為亂碼了！
參考例子： 複製代碼 代碼如下:<%@ 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");//直接擷取中文參數
}
try{
if(request.getParameter("param1")!=null){
str1=URLDecoder.decode(request.getParameter("param1"),"utf-8");//對中文參數進行解碼
}
}catch(Exception e){
e.printStackTrace();
}
%>
