通常，我們都是用以下代碼來獲取本地ip地址的
- InetAddress.getLocalHost().getHostAddress()
InetAddress.getLocalHost().getHostAddress()
這種方法在linux卻只能取到127.0.0.1這個(gè)讓人無奈的地址。。。這簡直是讓人不能忍受的啊。。。這種地址不用獲取，我們誰不知道。。。
在網(wǎng)上搜索了很多，發(fā)現(xiàn)說這個(gè)問題的并不多，所以，我把找到的一段代碼分享給大家。。。當(dāng)然這段代碼需要jdk1.5以上版本
- Enumeration<NetworkInterface> netInterfaces = null;
- try {
- netInterfaces = NetworkInterface.getNetworkInterfaces();
- while (netInterfaces.hasMoreElements()) {
- NetworkInterface ni = netInterfaces.nextElement();
- System.out.println("DisplayName:" + ni.getDisplayName());
- System.out.println("Name:" + ni.getName());
- Enumeration<InetAddress> ips = ni.getInetAddresses();
- while (ips.hasMoreElements()) {
- System.out.println("IP:"
- + ips.nextElement().getHostAddress());
- }
- }
- } catch (Exception e) {
- e.printStackTrace();
- }
Enumeration<NetworkInterface> netInterfaces = null;
try {
netInterfaces = NetworkInterface.getNetworkInterfaces();
while (netInterfaces.hasMoreElements()) {
NetworkInterface ni = netInterfaces.nextElement();
System.out.println("DisplayName:" + ni.getDisplayName());
System.out.println("Name:" + ni.getName());
Enumeration<InetAddress> ips = ni.getInetAddresses();
while (ips.hasMoreElements()) {
System.out.println("IP:"
+ ips.nextElement().getHostAddress());
}
}
} catch (Exception e) {
e.printStackTrace();
}
這段代碼會(huì)輸出計(jì)算機(jī)中所有設(shè)備的ip，找需要的用吧，呵呵
