HttpsCookieFilter-IllegalStateException：此响应已调用getOutputStream（）

[英]HttpsCookieFilter - IllegalStateException: getOutputStream() has already been called for this response

问题描述

偶尔会抛出以下异常，并且该异常会显示在tomcat日志目录中的localhost日志文件中。 如果有人知道如何摆脱它，所有帮助将不胜感激。 顺便说一句，过滤器工作正常，我只是不知道为什么会发生这种异常。

集成此过滤器的原因来自Spring安全性常见问题解答：

我正在使用Tomcat（或其他一些servlet容器），并且已为登录页面启用HTTPS，然后再切换回HTTP。 它不起作用-经过身份验证后，我只是回到登录页面。
发生这种情况是因为在HTTPS下创建的会话（会话cookie标记为“安全”）无法随后在HTTP下使用。 浏览器不会将cookie发送回服务器，并且任何会话状态都将丢失（包括安全上下文信息）。 首先使用HTTP启动会话应该可以正常工作，因为会话cookie不会被标记为安全。

解：

事实证明，罪魁祸首是： 

 @RequestMapping(value="/captcha.html", method = RequestMethod.GET)
 public ModelMap processCaptcha(HttpServletRequest request, HttpServletResponse response) throws Exception

简单地将方法的返回类型从ModalMap更改为void即可解决此问题。 谢谢@BalusC

过滤器与此无​​关。 这只是捕获未捕获的异常的地方。

作为异常提示，您不能在同一响应上同时调用getOutputStream()和getWriter() 。 那是非法状态。

正如stacktrace所暗示的那样，您似乎正在使用Freemarker，它隐式使用Writer编写响应主体。 因此，无论何时将响应委派给Freemarker，都应确保永远不要事先在代码中的任何位置调用response.getOutputStream() 。 或者，当调用它是强制性的（例如，编写一些二进制内容，然后将其作为下载内容提供）时，则应跳过将响应委派给Freemarker的操作。
