springboot 获取访问者的ip地址、访问设备信息、城市地址信息

1.获取访问者的ip地址：

    public static String getLocalIP() {

        if (System.getProperty("os.name").toLowerCase().startsWith("windows")) {

            return ip;
        } else {
            try {
                Enumeration<?> e1 = (Enumeration<?>) NetworkInterface
                        .getNetworkInterfaces();
                while (e1.hasMoreElements()) {
                    NetworkInterface ni = (NetworkInterface) e1.nextElement();

                        continue;

            }
        }
        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：

<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;

@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<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 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<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
