Java中如何获取当前服务器IP地址

获取服务器IP地址的实现思路
       借助 InetAddress.getLocalHost().getHostAddress()  

package com.java265.other;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class HuoQuIpDiZhi {

	/**
	 * java265.com 获取IP地址的方法及示例分享
	 */
	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.bing.com");
			// 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());
			System.out.println(address1.getCanonicalHostName());
			System.out.println(address1.getHostAddress());
			System.out.println("===============");
			// 用IP地址创建InetAddress对象
			InetAddress address2 = InetAddress.getByName("8.8.8.8");
			System.out.println(address2.getHostName());
			System.out.println(address2.getCanonicalHostName());
			System.out.println(address2.getHostAddress());
			System.out.println("===============");
			// 根据主机名返回其可能的所有InetAddress对象
			InetAddress[] addresses = InetAddress.getAllByName("www.java265.com");
			for (InetAddress addr : addresses) {
				System.out.println(addr);
			}
		} catch (UnknownHostException e) {
			e.printStackTrace();
		}
	}
