Ⅲ Java代码如何获取客户端的MAC地址
public String getMAC() { String mac = null; try { Process pro = Runtime.getRuntime().exec("cmd.exe /c ipconfig/all"); InputStream is = pro.getInputStream(); BufferedReader br = new BufferedReader(new InputStreamReader(is)); String message = br.readLine(); int index = -1; while (message != null) { if ((index = message.indexOf("Physical Address")) > 0) { mac = message.substring(index + 36).trim(); break; } message = br.readLine(); } System.out.println(mac); br.close(); pro.destroy(); } catch (IOException e) { System.out.println("Can't get mac address!"); return null; } return mac; }
Ⅳ 请问java如何获取手机mac地址
以windows举例。
运行命令" cmd ipconfig /all"就会出现以下结果
Physical Address. . . . . . . . . : 20-CF-30-9A-60-EE
。
java就能过这样的命令来获取。以下是示例。
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class TestMac
{
public static void main(String[] args) {
System.out.println("Operation System=" + getOsName());
System.out.println("Mac Address=" + getMACAddress());
System.out.println("通过ip获取mac"+getMACAddress("192.168.1.101"));
}
public static String getOsName() {
String os = "";
os = System.getProperty("os.name");
return os;
}
public static String getMACAddress() {
String address = "";
String os = getOsName();
if (os.startsWith("Windows")) {
try {
String command = "cmd.exe /c ipconfig /all";
Process p = Runtime.getRuntime().exec(command);
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
if (line.indexOf("Physical Address") > 0) {
int index = line.indexOf(":");
index += 2;
address = line.substring(index);
break;
}
}
br.close();
return address.trim();
} catch (IOException e) {
}
} else if (os.startsWith("Linux")) {
String command = "/bin/sh -c ifconfig -a";
Process p;
try {
p = Runtime.getRuntime().exec(command);
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
if (line.indexOf("HWaddr") > 0) {
int index = line.indexOf("HWaddr") + "HWaddr".length();
address = line.substring(index);
break;
}
}
br.close();
} catch (IOException e) {
}
}
address = address.trim();
return address;
}
public static String getMACAddress(String ipAddress) {
String str = "", strMAC = "", macAddress = "";
try {
Process pp = Runtime.getRuntime().exec("nbtstat -a " + ipAddress);
InputStreamReader ir = new InputStreamReader(pp.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
for (int i = 1; i < 100; i++) {
str = input.readLine();
if (str != null) {
if (str.indexOf("MAC Address") > 1) {
strMAC = str.substring(str.indexOf("MAC Address") + 14,
str.length());
break;
}
}
}
} catch (IOException ex) {
return "Can't Get MAC Address!";
}
//
if (strMAC.length() < 17) {
return "Error!";
}
macAddress = strMAC.substring(0, 2) + ":" + strMAC.substring(3, 5)
+ ":" + strMAC.substring(6, 8) + ":" + strMAC.substring(9, 11)
+ ":" + strMAC.substring(12, 14) + ":"
+ strMAC.substring(15, 17);
//
return macAddress;
}
}
剑天梦的回答原理和我这个一样,都是通过Process 执行命令。 我直接补充到答案里了。不过
我这边运行那个命令出来的结果很多,那么花的时间就长了。优点是能够获取别人的mac地址 。
Ⅳ java 获取无线 mac地址吗
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.LineNumberReader;
public class GetMac {
/**
* java获取客户端网卡的MAC地址
*
* @param args
*/
public static void main(String[] args) {
GetMac get = new GetMac();
System.out.println("1="+get.getMAC());
System.out.println("2="+get.getMAC("127.0.0.1"));
}
// 1.获取客户端ip地址( 这个必须从客户端传到后台):
// jsp页面下,很简单,request.getRemoteAddr() ;
// 因为系统的VIew层是用JSF来实现的,因此页面上没法直接获得类似request,在bean里做了个强制转换
// public String getMyIP() {
// try {
// FacesContext fc = FacesContext.getCurrentInstance();
// HttpServletRequest request = (HttpServletRequest) fc
// .getExternalContext().getRequest();
// return request.getRemoteAddr();
// } catch (Exception e) {
// e.printStackTrace();
// }
// return "";
// }
// 2.获取客户端mac地址
// 调用window的命令,在后台Bean里实现 通过ip来获取mac地址。方法如下:
// 运行速度【快】
public String getMAC() {
String mac = null;
try {
Process pro = Runtime.getRuntime().exec("cmd.exe /c ipconfig/all");
InputStream is = pro.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String message = br.readLine();
int index = -1;
while (message != null) {
if ((index = message.indexOf("Physical Address")) > 0) {
mac = message.substring(index + 36).trim();
break;
}
message = br.readLine();
}
System.out.println(mac);
br.close();
pro.destroy();
} catch (IOException e) {
System.out.println("Can't get mac address!");
return null;
}
return mac;
}
// 运行速度【慢】
public String getMAC(String ip) {
String str = null;
String macAddress = null;
try {
Process p = Runtime.getRuntime().exec("nbtstat -A " + ip);
InputStreamReader ir = new InputStreamReader(p.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
for (; true;) {
str = input.readLine();
if (str != null) {
if (str.indexOf("MAC Address") > 1) {
macAddress = str
.substring(str.indexOf("MAC Address") + 14);
break;
}
}
}
} catch (IOException e) {
e.printStackTrace(System.out);
return null;
}
return macAddress;
}
}

以下代码实现浏览器中获取mac地址放入一个输入框或隐藏域,随登录信息一起提交到服务器。因为安全级别的关系可能会出现警告,可选择允许执行。长期使用的话建议用户将改站点加入信任站点或把安全级别调低。

Ⅸ java怎么获取系统mac地址
首先,创建工程,包,和一个类。
在此不加详述,我们直接看代码。
这里,我把这个类命名为GetMacAddr
这里,最最关键的就是这里这个方法。
我们通过NetworkInterface这个类来操作。
也就是通过getLocalHost()方法先得到本机IP,
然后调用getHardwareAddress()方法得到一个byte数组的地址。
我们把六位地址传到一个byte数组里面,然后输出来就是。
不多废话,看代码:
private void getMACAddr()
throws SocketException, UnknownHostException {
// 获得IP
NetworkInterface netInterface =
NetworkInterface.getByInetAddress(InetAddress.getLocalHost());
// 获得Mac地址的byte数组
byte[] macAddr = netInterface.getHardwareAddress();
System.out.print("MAC Addr:\t");
// 循环输出
for (byte b : macAddr) {
// 这里的toHexString()是自己写的格式化输出的方法,见下步。
System.out.print(toHexString(b) + " ");
}
}
上一步骤中,为什么会出现一个toHexString()方法呢?
因为可能10进制转16进制时候可能会出现单字符,
所以,如果有出现单字符的情况,我们在其前面添加一个“0”做占位符。
这也是为了视觉的直观,也夹带着个人的习惯。
private static String toHexString(int integer) {
// 将得来的int类型数字转化为十六进制数
String str = Integer.toHexString((int) (integer & 0xff));
// 如果遇到单字符,前置0占位补满两格
if (str.length() == 1) {
str = "0" + str;
}
return str;
}
