禁用浏览器缓存

Java 代码 设置response header

        response.setDateHeader("Expires", 0);
        response.setHeader("Cache-Control", "no-cache");
        response.setHeader("Pragma", "no-cache");

HTML在head设置

<meta http-equiv="Expires" content="0" />
<meta http-equiv="Cache-Control" content="no-cache" />
<meta http-equiv="Pragma" content="no-cache" />
