javascript通过url向jsp页面传递中文参数导致乱码解决方案

%@ 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");//直接获取中文参数
}
try{
if(request.getParameter("param1")!=null){
str1=URLDecoder.decode(request.getParameter("param1"),"utf-8");//对中文参数进行解码
}
}catch(Exception e){
e.printStackTrace();
}
