1.获取访问者的ip地址：
不多说直接上代码，详解见注释 package com.xr.util; import lombok.extern.slf4j.Slf4j; import javax.servlet.http.HttpServletRequest; import java.net.*; import java.util.Enumeration; /** *@Author: make mpy *@Description: 获取IP的方法 *@Date: 2021/1/18 15:02 */ @Slf4j public class IpUtil { private static final String LOCAL_IP = "127.0.0.1"; /** * 获取IP地址 * * 使用Nginx等反向代理软件， 则不能通过request.getRemoteAddr()获取IP地址 * 如果使用了多级反向代理的话，X-Forwarded-For的值并不止一个，而是一串IP地址，X-Forwarded-For中第一个非unknown的有效IP字符串，则为真实IP地址 */ public static String getIpAddr(HttpServletRequest request) { if (request == null) { return "unknown"; } String ip = request.getHeader("x-forwarded-for"); if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("Proxy-Client-IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("X-Forwarded-For"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("WL-Proxy-Client-IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("X-Real-IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getRemoteAddr(); } return "0:0:0:0:0:0:0:1".equals(ip) ? LOCAL_IP : ip; } public static boolean internalIp(String ip) { boolean res = false; byte[] addr = textToNumericFormatV4(ip); if (addr != null && ip != null) { res = internalIp(addr) || LOCAL_IP.equals(ip); } return res; } private static boolean internalIp(byte[] addr) { final byte b0 = addr[0]; final byte b1 = addr[1]; // 10.x.x.x/8 final byte SECTION_1 = 0x0A; // 172.16.x.x/12 final byte SECTION_2 = (byte) 0xAC; final byte SECTION_3 = (byte) 0x10; final byte SECTION_4 = (byte) 0x1F; // 192.168.x.x/16 final byte SECTION_5 = (byte) 0xC0; final byte SECTION_6 = (byte) 0xA8; boolean flag = false; switch (b0) { case SECTION_1: flag = true; break; case SECTION_2: if (b1 >= SECTION_3 && b1 4294967295L)) return null; bytes[0] = (byte) (int) (l >> 24 & 0xFF); bytes[1] = (byte) (int) ((l & 0xFFFFFF) >> 16 & 0xFF); bytes[2] = (byte) (int) ((l & 0xFFFF) >> 8 & 0xFF); bytes[3] = (byte) (int) (l & 0xFF); break; case 2: l = Integer.parseInt(elements[0]); if ((l < 0L) || (l > 255L)) return null; bytes[0] = (byte) (int) (l & 0xFF); l = Integer.parseInt(elements[1]); if ((l < 0L) || (l > 16777215L)) return null; bytes[1] = (byte) (int) (l >> 16 & 0xFF); bytes[2] = (byte) (int) ((l & 0xFFFF) >> 8 & 0xFF); bytes[3] = (byte) (int) (l & 0xFF); break; case 3: for (i = 0; i < 2; ++i) { l = Integer.parseInt(elements[i]); if ((l < 0L) || (l > 255L)) return null; bytes[i] = (byte) (int) (l & 0xFF); } l = Integer.parseInt(elements[2]); if ((l < 0L) || (l > 65535L)) return null; bytes[2] = (byte) (int) (l >> 8 & 0xFF); bytes[3] = (byte) (int) (l & 0xFF); break; case 4: for (i = 0; i < 4; ++i) { l = Integer.parseInt(elements[i]); if ((l < 0L) || (l > 255L)) return null; bytes[i] = (byte) (int) (l & 0xFF); } break; default: return null; } } catch (NumberFormatException e) { log.error("数字格式化异常",e); return null; } return bytes; } public static String getLocalIP() { String ip = ""; if (System.getProperty("os.name").toLowerCase().startsWith("windows")) { InetAddress addr; try { addr = InetAddress.getLocalHost(); ip = addr.getHostAddress(); } catch (UnknownHostException e) { log.error("获取失败",e); } return ip; } else { try { Enumeration e1 = (Enumeration) NetworkInterface .getNetworkInterfaces(); while (e1.hasMoreElements()) { NetworkInterface ni = (NetworkInterface) e1.nextElement(); if (!ni.getName().equals("eth0")) { continue; } else { Enumeration e2 = ni.getInetAddresses(); while (e2.hasMoreElements()) { InetAddress ia = (InetAddress) e2.nextElement(); if (ia instanceof Inet6Address) continue; ip = ia.getHostAddress(); return ip; } break; } } } catch (SocketException e) { log.error("获取失败",e); } } return ""; } }在控制类里使用： @RequestMapping("login") public ResponseResult login( HttpServletRequest request){ ResponseResult result=new ResponseResult(); String ipAddress = IpUtil.getIpAddr(request); System.out.println(ipAddress); result.getData().put("message",ipAddress); return result; } 2.获取访问设备信息：Spring Mobile是一个框架，该框架提供的功能可以检测向您的Spring网站发出请求的设备的类型，并基于该设备提供其他视图。像所有Spring项目一样，Spring Mobile的真正强大之处在于它的扩展容易程度。 特征 设备解析器抽象，用于移动和平板设备的服务器端检测 网站首选项管理，允许用户指示他或她是否喜欢“正常”，“移动”或“平板电脑”体验 站点切换器，能够根据用户的设备和显示的站点首选项，将用户切换到最适合的网站，无论是手机，平板电脑还是普通网站 设备感知视图管理，用于组织和管理特定设备的不同视图 SpringBoot配置： 1.要使用Spring Mobile,需要在项目的pom.xml里添加以下依赖： org.springframework.boot spring-boot-starter-mobile 1.5.9.RELEASE2.添加以下基于Java的配置以在Spring Web应用程序中启用设备检测： package com.xr.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.mobile.device.DeviceHandlerMethodArgumentResolver; import org.springframework.mobile.device.DeviceResolverHandlerInterceptor; import org.springframework.mobile.device.site.SitePreferenceHandlerInterceptor; import org.springframework.mobile.device.site.SitePreferenceHandlerMethodArgumentResolver; import org.springframework.web.method.support.HandlerMethodArgumentResolver; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; import java.util.List; @Configuration public class MobileConfig implements WebMvcConfigurer { @Bean public DeviceResolverHandlerInterceptor deviceResolverHandlerInterceptor() { return new DeviceResolverHandlerInterceptor(); } @Bean public DeviceHandlerMethodArgumentResolver deviceHandlerMethodArgumentResolver() { return new DeviceHandlerMethodArgumentResolver(); } @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new DeviceResolverHandlerInterceptor()); } @Override public void addArgumentResolvers(List argumentResolvers) { argumentResolvers.add(new DeviceHandlerMethodArgumentResolver()); } }2.将Device注入你的控制器： @RequestMapping("about") public void about(Device device){ if (device.isMobile()) { System.out.println("========请求来源设备是手机！========"); } else if (device.isTablet()) { System.out.println("========请求来源设备是平板！========"); } else if(device.isNormal()){ System.out.println("========请求来源设备是PC！========"); }else { System.out.println("========请求来源设备是其它！========"); } } 3.获取访问ip城市地址信息：1、去腾讯位置服务进行开发者注册 2、通过访问控制台中key管理，申请key 4、创建查找位置的工具类 package com.xr.util; import com.alibaba.fastjson.JSONObject; import java.io.BufferedReader; import java.io.InputStreamReader; import java.net.URL; import java.net.URLConnection; import java.util.List; import java.util.Map; public class IpToAddressUtil { //使用腾讯的接口通过ip拿到城市信息 private static final String KEY = "自己的key"; public static String getCityInfo(String ip) { String s = sendGet(ip, KEY); Map map = JSONObject.parseObject(s, Map.class); String message = (String) map.get("message"); if("query ok".equals(message)){ Map result = (Map) map.get("result"); Map addressInfo = (Map) result.get("ad_info"); String nation = (String) addressInfo.get("nation"); String province = (String) addressInfo.get("province"); // String district = (String) addressInfo.get("district"); String city = (String) addressInfo.get("city"); String address = nation + "-" + province + "-" + city; return address; }else{ System.out.println(message); return null; } } //根据在腾讯位置服务上申请的key进行请求操作 public static String sendGet(String ip, String key) { String result = ""; BufferedReader in = null; try { String urlNameString = "https://apis.map.qq.com/ws/location/v1/ip?ip="+ip+"&key="+key; URL realUrl = new URL(urlNameString); // 打开和URL之间的连接 URLConnection connection = realUrl.openConnection(); // 设置通用的请求属性 connection.setRequestProperty("accept", "*/*"); connection.setRequestProperty("connection", "Keep-Alive"); connection.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)"); // 建立实际的连接 connection.connect(); // 获取所有响应头字段 Map map = connection.getHeaderFields(); // 遍历所有的响应头字段 // for (Map.Entry entry : map.entrySet()) { // System.out.println(key + "--->" + entry); // } // 定义 BufferedReader输入流来读取URL的响应 in = new BufferedReader(new InputStreamReader( connection.getInputStream())); String line; while ((line = in.readLine()) != null) { result += line; } } catch (Exception e) { System.out.println("发送GET请求出现异常！" + e); e.printStackTrace(); } // 使用finally块来关闭输入流 finally { try { if (in != null) { in.close(); } } catch (Exception e2) { e2.printStackTrace(); } } return result; } }5、在控制类里直接调用就OK

3、在key设置里设置白名单，否则有key也不能成功调用接口。 包括域名白名单和授权ip，一般是自己本机和服务器的ip
