                 ipAddress = request.getRemoteAddr();

                 if (ipAddress.equals( "127.0.0.1" )) {

                     // 根据网卡取本机配置的IP

                     InetAddress inet = null ;

                     try {

                         inet = InetAddress.getLocalHost();

                     } catch (UnknownHostException e) {

                         e.printStackTrace();

                     }

                     ipAddress = inet.getHostAddress();

                 }

             }

             // 对于通过多个代理的情况,第一个IP为客户端真实IP,多个IP按照','分割

             if (ipAddress != null && ipAddress.length() > 15 ) { // "***.***.***.***".length()

                 // = 15

                 if (ipAddress.indexOf( "," ) > 0 ) {

                     ipAddress = ipAddress.substring( 0 , ipAddress.indexOf( "," ));

                 }

             }

         } catch (Exception e) {

             ipAddress= "" ;

         }

         // ipAddress = this.getRequest().getRemoteAddr();

 

         return ipAddress;

     }

}

方法调用:

(当接口 /test 被调用,request就能自动获取出来,然后调用工具类方法进行解析获取了。)

@RequestMapping (value = "/test" , method = RequestMethod.GET)

     String ipAddress =IpUtil.getIpAddr(request);

   

     return ipAddress;

}
