jsp 乱码 怎么解决？
<%@ page language="java" import="java.sql.*" pageEncoding="utf-8"%><%!
String Spname = "请输入商品名称";
String pname1;
//转码代码
String changeString(String str){
try{
byte[]b = str.getBytes("ISO-8859-1");
str = new String(b,"utf-8");
}catch(Exception e){
}
return str;
}

request.setCharacterEncoding("utf-8");
String pname = changeString(request.getParameter("pname"));
pname1 = pname;
System.out.println(pname);
session.setAttribute("Rpname", pname);
Spname = (String) session.getAttribute("Rpname");
if (Spname == null) {
Spname = "请输入商品名称";
}

<center>
您要检索商品为：
<input type="text" name="pname" value="<%=Spname%>" />
<input type="submit" value="检索" />
<br />
<br />
