我一直在尝试使用下面的代码来获得用户的IP和我得到这个输出。如何获取访问网站网址的用户ip？
InetAddress.getLocalHost（）的gethostname（）：ANKUR-PC
InetAddress.getLocalHost（）getHostAddress （）：10.0.0.2
request.getLocalAddr（）：0.0.0.0
request.getLocalName（）：0.0.0.0
request.getRemoteAddr（）：0： 0：0：0：0：0：0：1
request.getRemoteHost（）：0：0：0：0：0：0：0：1个
request.getHeader（“代理客户端-IP “）：空
request.getHeader（” WL-代理客户端IP “）：空
request.getHeader（” X转发-FOR“）：空
的InetAddress。 getByName（request.getHeader（“X-FORWARDED-FOR”））： localhost/127.0.0.1
InetAddress.getByName（request.getRemoteAddr（））：/ 0：0：0：0：0：0：0：1
InetAddress.getByName（request.getRemoteHost（））：/ 0：0：0 ：0：0：0：0：1
我不知道它的正确与否。请给我一些建议，因为我是新手。
