Java里面获取当前服务器的IP地址

public static void main(String[] args) {
        try {
            //用 getLocalHost() 方法创建的InetAddress的对象
            InetAddress address = InetAddress.getLocalHost();
            System.out.println(address.getHostName());//主机名
            System.out.println(address.getCanonicalHostName());//主机别名
            System.out.println(address.getHostAddress());//获取IP地址
            System.out.println("===============");
            
            //用域名创建 InetAddress对象
            InetAddress address1 = InetAddress.getByName("www.wodexiangce.cn");
            //获取的是该网站的ip地址，如果我们所有的请求都通过nginx的，所以这里获取到的其实是nginx服务器的IP地址
            System.out.println(address1.getHostName());//www.wodexiangce.cn
            System.out.println(address1.getCanonicalHostName());//124.237.121.122
            System.out.println(address1.getHostAddress());//124.237.121.122
            System.out.println("===============");
            
            //用IP地址创建InetAddress对象
            InetAddress address2 = InetAddress.getByName("220.181.111.188");
            System.out.println(address2.getHostName());//220.181.111.188
            System.out.println(address2.getCanonicalHostName());//220.181.111.188
            System.out.println(address2.getHostAddress());//220.181.111.188
            System.out.println("===============");
            
            //根据主机名返回其可能的所有InetAddress对象
            InetAddress[] addresses = InetAddress.getAllByName("www.baidu.com");
            for (InetAddress addr : addresses) {
                System.out.println(addr);
                //www.baidu.com/220.181.111.188
                //www.baidu.com/220.181.112.244
            }
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
    }

public class CommonServerIP {
    /**
     * 这个类主要是保存常用的一些固定的服务器IP
     */
     public static String CURRENT_SERVER="124.237.121.46";//当前服务器的ip地址
}
