本文档介绍了如何在Java中通过HttpServletRequest获取请求的IP地址，重点讲解了`x-forwarded-for`和`remoteAddr`的区别，并提供了一个示例方法getRemortIP()。

    private String getRemortIP() throws Exception {
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        String ip = "";
        if (request.getHeader("x-forwarded-for") == null) {
            ip = request.getRemoteAddr();
        }else{
            ip = request.getHeader("x-forwarded-for");
        }
        return ip;
    }
