Spring MVC如何处理浏览器后退按钮

我用这种方法。首先创建一个实现Filter的类并重写doFilter（）方法。doFilter（）的代码是：

 @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {HttpServletResponse hsr = (HttpServletResponse) res;hsr.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.hsr.setHeader("Pragma", "no-cache"); // HTTP 1.0.hsr.setDateHeader("Expires", 0); // Proxies.chain.doFilter(req, res); }

之后在web.xml中使用过滤器。这个过滤器就是这个。

  <filter>    <filter-name>noCacheFilter</filter-name>    <filter-class>com.example.NoCacheFilter</filter-class> </filter> <filter-mapping>  <filter-name>noCacheFilter</filter-name>  <url-pattern>/secured/*.jsp</url-pattern>// urls that not cached  </filter-mapping>
