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;
    }
