乱码问题？

Question

文件头上加：
<%@ page contentType="text/html; charset=GBK" %>

Answer 1

在jsp的第一行加上
<%@ page contentType="text/html; charset=GBK" %>

Answer 2

response.setHeader("Cache-Control","no-store");
response.setHeader("Cache-Control","Max-stale=0");
response.setHeader("Pragma","no-cache");
response.setHeader("Expires","-1");
response.setHeader("Max-age","0");
response.setContentType("text/html;charset=gbk");
加了这个还不行的话，就真要字符转换了

Answer 3

<%@ page contentType="text/html; charset=gb2312" %>
