<%@ page language="java" pageEncoding="UTF-8"%>
< !-- 告诉浏览器该jsp格式为utf-8，此时注意网页本身(右击->properties)的编码是否为utf-8 -->
在head内加入：
< meta http-equiv="Content-Type" content="text/html; charset=utf-8">
对于get请求：
String name2 = new String(name.getBytes("iso-8859-1"),"UTF-8");
对于post请求
request.setCharacterEncoding("utf-8");//对于post方法有效，对get无效.一定要放在解析的第一行，否则不行。
String name = request.getParameter("name");
