基础名词解析（二）springmvc中的RequestContextHolder

RequestContextHolder

当我们需要在service层获取request和response时，我们可以在RequestContextHolder中获取。
使用方法：

        RequestAttributes requsetAttributes = RequestContextHolder.currentRequestAttributes();
		//RequestAttributes requsetAttributes = RequestContextHolder.getRequestAttributes();
		String str = (String) requsetAttributes.getAttribute("name", RequestAttributes.SCOPE_SESSION);
		HttpServletRequest request = ((ServletRequestAttributes) requsetAttributes).getRequest();
		HttpServletResponse reponse = ((ServletRequestAttributes) requsetAttributes).getResponse();
