问题描述

Spring Security是否有办法防止出现最后一个问题？我正在使用3.0.5
用户登录我的网站
-用户转到网站上的任何页面，然后单击注销
-登出链接使用户会话无效，并将其发送到我网站的登录页面
-在同一浏览器中，用户导航到新网站（例如cnn.com）
-用户单击“后退”按钮，他们进入我的登录页面
-用户再次单击“后退”按钮，它们最终出现在应用程序中可能包含我们不希望存在的数据的页面上。如果他们单击页面上的任何链接，则立即将其发送到登录页面，但是他们可以从浏览器缓存中查看缓存的页面……以任何不让他们查看此内容的方式？

解决方法
下面的过滤器照顾了我的情况：
package com.dc.api.service.impl;
import javax.servlet.*;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Date;
public class CacheControlFilter implements Filter {
public void doFilter(ServletRequest request,ServletResponse response,FilterChain chain) throws IOException,ServletException {
HttpServletResponse resp = (HttpServletResponse) response;
resp.setHeader(\"Expires\",\"Tue,03 Jul 2001 06:00:00 GMT\");
resp.setHeader(\"Last-Modified\",new Date().toString());
resp.setHeader(\"Cache-Control\",\"no-store,no-cache,must-revalidate,max-age=0,post-check=0,pre-check=0\");
resp.setHeader(\"Pragma\",\"no-cache\");
chain.doFilter(request,response);
}
@Override
public void destroy() {}
@Override
public void init(FilterConfig arg0) throws ServletException {}
}
