获取request的两种方式

1、在filter中获取Request

• HttpServletRequest req = RequestContext.getCurrentContext().getRequest();
• RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
• req = ((ServletRequestAttributes) requestAttributes).getRequest();

2、在controller和service中获取Request　

• RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
• req = ((ServletRequestAttributes) requestAttributes).getRequest();
