1.获取访问者的ip地址：
不多说直接上代码，详解见注释

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：
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mobile</artifactId><version>1.5.9.RELEASE</version></dependency>
2.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;@Configurationpublic class MobileConfig implements WebMvcConfigurer {@Beanpublic DeviceResolverHandlerInterceptor deviceResolverHandlerInterceptor() {return new DeviceResolverHandlerInterceptor();}@Beanpublic DeviceHandlerMethodArgumentResolverdeviceHandlerMethodArgumentResolver() {return new DeviceHandlerMethodArgumentResolver();}@Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(new DeviceResolverHandlerInterceptor());}@Overridepublic void addArgumentResolvers(List<HandlerMethodArgumentResolver> 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
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
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 .URL;import .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./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<String, List<String>> 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
