关于spring MVC中获取客户端的IP地址

1. 引入HttpServletRequest

     @Autowired
     private HttpServletRequest request;

2. 获取IP地址

     private static String getClientIp(HttpServletRequest request) {
         String remoteAddr = "";
         if (request != null) {
             remoteAddr = request.getHeader("X-FORWARDED-FOR");
             if (remoteAddr == null || "".equals(remoteAddr)) {
                 remoteAddr = request.getRemoteAddr();
             }
         }
         return remoteAddr;
     }
