这里只需要在 JSP 代码块当中加入
<%
response.setHeader("Pragma","No-cache");
response.setHeader("Cache-Control","no-cache");
response.setHeader("Cache-Control", "no-store");
response.setDateHeader("Expires", 0);
%>
在 HTML 头部加入以下 META 信息
<meta http-equiv="Expires" content="0">
<meta http-equiv="Cache-Control" content="no-cache">
<meta http-equiv="Cache-Control" content="no-store">
<meta http-equiv="Pragma" content="no-cache">
