java获取手机当前IP地址 java获取本机ip的方法

1、Java获取本地IP地址方法网上搜一箩筐，但基本上都是获得一个IP，实际开发中一台电脑很可能有多个IP地址，如多网卡，或者安装了VM Ware虚拟机，就会虚拟出其他的网卡，那么传统的方法得到的一个IP地址就不全面了，下面贴出获取本机IP列表的方法：

 public  
 static List<String> getLocalIPList()  
 {
        List<String> ipList = new ArrayList<String>();
        try {
            Enumeration<NetworkInterface> networkInterfaces = NetworkInterface.getNetworkInterfaces();
            NetworkInterface networkInterface;
            Enumeration<InetAddress> inetAddresses;
            InetAddress inetAddress;
            String ip;
            while (networkInterfaces.hasMoreElements()) {
                networkInterface = networkInterfaces.nextElement();
                inetAddresses = networkInterface.getInetAddresses();
                while (inetAddresses.hasMoreElements()) {
                    inetAddress = inetAddresses.nextElement();
                    if (inetAddress != null && inetAddress instanceof Inet4Address) { // IPV4
                        ip = inetAddress.getHostAddress();
                        ipList.add(ip);
                    }
                }
            }
        } catch (SocketException e) {
            e.printStackTrace();
        }
        return ipList;
    }

2、获取多网卡时的本机IP

1. public String getLocalHostName() {  
2.         String hostName;  
3. try {  
4.             InetAddress addr = InetAddress.getLocalHost();  
5.             hostName = addr.getHostName();  
6. catch (Exception ex) {  
7. "";  
8.         }  
9. return hostName;  
10.     }  
11.   
12. public String[] getAllLocalHostIP() {  
13. null;  
14. try {  
15.         String hostName = getLocalHostName();  
16. if (hostName.length() > 0) {  
17.             InetAddress[] addrs = InetAddress.getAllByName(hostName);  
18. if (addrs.length > 0) {  
19. new String[addrs.length];  
20. for (int i = 0; i < addrs.length; i++) {  
21.                     ret[i] = addrs[i].getHostAddress();  
22.                 }  
23.             }  
24.         }  
25.   
26. catch (Exception ex) {  
27. null;  
28.         }  
29. return ret;  
30.     }
