在很多时候项目中用到了HttpServletResponse 和 HttpServletRequest 但是无法获取到，参考了很多文章，以下为亲自试验可以使用：

ServletRequestAttributes servletContext = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();//获取HttpServletResponseHttpServletResponse response = servletContext.getResponse();//获取HttpServletRequestHttpServletRequest request = servletContext.getRequest();
