  • 使用java获取本机ip,过滤掉回环地址127.0.0.1

    import java.net.Inet4Address;
    import java.net.InetAddress;
    import java.net.NetworkInterface;
    import java.net.SocketException;
    import java.net.UnknownHostException;
    import java.util.Enumeration;
    
    public class TestAddress {
    
        public static void main(String[] args) throws UnknownHostException {
            System.out.println(InetAddress.getLocalHost().getHostAddress());
            System.out.println(InetAddress.getLocalHost().getHostName());
            System.out.println(InetAddress.getLocalHost().getCanonicalHostName());
            System.out.println("================================");
            System.out.println(getCurrentIp().getHostAddress());
        }
    
        
        public static InetAddress getCurrentIp() {
            try {
                Enumeration<NetworkInterface> networkInterfaces = NetworkInterface.getNetworkInterfaces();
                while (networkInterfaces.hasMoreElements()) {
                    NetworkInterface ni = (NetworkInterface) networkInterfaces.nextElement();
                    Enumeration<InetAddress> nias = ni.getInetAddresses();
                    while (nias.hasMoreElements()) {
                        InetAddress ia = (InetAddress) nias.nextElement();
                        if (!ia.isLinkLocalAddress() && !ia.isLoopbackAddress() && ia instanceof Inet4Address) {
                            return ia;
                        }
                    }
                }
            } catch (SocketException e) {
                System.err.println(e.getStackTrace());
            }
            return null;
        }
    }

    使用方法:

    拷贝文件到机器上,

    使用 javac TestAddress.java 编译代码

    使用java TestAddress 命令 运行

    查看输出

    以上前提是安装了java环境
