获得客户端公网ip以及ip2region转为省市运营商

1. 获得公网ip

1. 工具类

这个工具类就是在icanhazip.com查到你的公网ip

public class Iputil {
    //必须分开写，
    // 不能有空格String localIP = IPUtil.execCurl().trim();
    //获取公网ip
    public static String execCurl() {
        String[] cmds={"curl","icanhazip.com"};
        ProcessBuilder process = new ProcessBuilder(cmds);
        Process p;

        try {
            p = process.start();
            BufferedReader reader 
            = new BufferedReader(new InputStreamReader(p.getInputStream()));
            StringBuilder builder = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                builder.append(line);builder.append(System.getProperty("line.separator"));
            }
            return builder.toString();
        } catch (IOException e) {
            System.out.print("error");e.printStackTrace();
        }
        return null;
    }
}

2.使用

 String ip = Iputil.execCurl().trim();
            System.out.println(ip);

2.ip2region转为省市运营商

1. jar包

<!-- Ip地址获取 -->
        <dependency>
            <groupId>net.dreamlu</groupId>
            <artifactId>mica-ip2region</artifactId>
            <version>2.5.4</version>
        </dependency>

2. 使用

 String[] address=ip2regionSearcher.getAddressAndIsp(ip).split(" ");
        System.out.println(Arrays.toString(address));
