JAVA獲取本機IP和Mac地址
阿新 • • 發佈:2021-02-01
專案中有個需要要獲取本機的Ip或是Mac地址,進行身份和許可權驗證,本文記錄一下java程式碼獲取ip和Mac。
package com.lgdz.hclient.utils;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
/**
* @建立人 duo
* @建立時間 2021-01-22
* @郵箱 [email protected]
* @作用
*/
public class LOCALMAC {
/**
* @param args
* @throws UnknownHostException
* @throws SocketException
*/
public static void main(String[] args) throws UnknownHostException, SocketException {
// TODO Auto-generated method stub
//得到IP,輸出PC-201309011313/122.206.73.83
InetAddress ia = InetAddress.getLocalHost();
System.out.println(ia);
getLocalMac(ia);
}
private static void getLocalMac(InetAddress ia) throws SocketException {
// TODO Auto-generated method stub
//獲取網絡卡,獲取地址
byte[] mac = NetworkInterface.getByInetAddress (ia).getHardwareAddress();
System.out.println("mac陣列長度:"+mac.length);
StringBuffer sb = new StringBuffer("");
for(int i=0; i<mac.length; i++) {
if(i!=0) {
sb.append("-");
}
//位元組轉換為整數
int temp = mac[i]&0xff;
String str = Integer.toHexString(temp);
System.out.println("每8位:"+str);
if(str.length()==1) {
sb.append("0"+str);
}else {
sb.append(str);
}
}
System.out.println("本機MAC地址:"+sb.toString().toUpperCase());
}
}
執行效果
