jsp的表单数据提交，中文出现乱码的处理

只需要在jsp里加

<%  request.setCharacterEncoding( "utf-8");%>
<% response.setCharacterEncoding("utf-8"); %>

cart.jsp

<%@ page language="java" contentType="text/html; charset=gbk"
    pageEncoding="utf-8"%>



<%  request.setCharacterEncoding( "utf-8");%>
<% response.setCharacterEncoding("utf-8"); %>
