springmvc获取response时

HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
HttpServletResponse response = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getResponse();

报错ServletRequestAttributes cannot be resolved to a type，不缺包

看看你的XML中是否少了这一段配置：



org.springframework.web.context.request.RequestContextListener

写了呀

org.springframework.web.context.request.RequestContextListener

直接用modle转发出去不用response就行了
还有把你是在获取response出的错误，根本不是这么获取的，

HttpServletResponse response = ((ServletWebRequest)RequestContextHolder.getRequestAttributes()).getResponse();
