獲取MAC地址，我需要從設備獲取MAC地址時，此MAC地址應該是所有類型的這種設備和時間不變的是獨一無二的。我讀了很多話題並嘗試過，但沒有一種方法沒有幫助。以下是我使用的所有方法。如何從設備
從主板：
public static String getMotherboardSN() {
String result = "";
try {
File file = File.createTempFile("realhowto", ".vbs");
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
String vbs =
"Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")\n"
+ "Set colItems = objWMIService.ExecQuery _ \n"
+ " (\"Select * from Win32_BaseBoard\") \n"
+ "For Each objItem in colItems \n"
+ " Wscript.Echo objItem.SerialNumber \n"
+ " exit for ' do the first cpu only! \n"
+ "Next \n";
fw.write(vbs);
fw.close();
Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath());
BufferedReader input =
new BufferedReader
(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null) {
result += line;
}
input.close();
} catch (Exception e) {
e.printStackTrace();
}
return result.trim();
}
從HDD：
public static String getSerialNumber(String drive) {
String result = "";
try {
File file = File.createTempFile("realhowto",".vbs");
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
String vbs = "Set objFSO = CreateObject(\"Scripting.FileSystemObject\")\n"
+"Set colDrives = objFSO.Drives\n"
+"Set objDrive = colDrives.item(\"C\")\n"
+"Wscript.Echo objDrive.SerialNumber"; // see note
fw.write(vbs);
fw.close();
Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath());
BufferedReader input =
new BufferedReader
(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null) {
result += line;
}
input.close();
}
catch(Exception e){
e.printStackTrace();
}
return result.trim();
}
從CPU：
private static String getWindowsCPU_SerialNumber() {
String result = "";
try {
File file = File.createTempFile("realhowto",".vbs");
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
String vbs1=
"Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")\n"
+ "Set colItems = objWMIService.ExecQuery _ \n"
+ " (\"Select * from Win32_Processor\") \n"
+ "For Each objItem in colItems \n"
+ " Wscript.Echo objItem.ProcessorId \n"
+ " exit for ' do the first cpu only! \n"
+ "Next \n";
fw.write(vbs1);
fw.close();
Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null) {
result += line;
}
input.close();
}
catch(Exception E){
System.err.println("Windows CPU Exp : "+E.getMessage());
}
return result.trim();
}
這是從UUID：
private void getUUID(){
String uniqueID = UUID.randomUUID().toString();
System.out.println(uniqueID);
}
從InetAddress類：
private void getMacFromInetAddress(){
String mmm = "123";
try {
InetAddress ip = InetAddress.getLocalHost();
System.out.println("Current IP address : " + ip.getHostAddress());
Enumeration<NetworkInterface> networks = NetworkInterface.getNetworkInterfaces();
while (networks.hasMoreElements()) {
NetworkInterface network = networks.nextElement();
byte[] mac = network.getHardwareAddress();
if (mac != null) {
System.out.print("Current MAC address : ");
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++) {
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
}
mmm = sb.toString();
System.out.println(mmm);
}
}
} catch (UnknownHostException | SocketException e) {
System.out.println(e.getLocalizedMessage());
}
}
在從MB，硬盤，CPU的方法，InetAddress類如果我上運行多個相同參數的計算機代碼，它們將返回相同的代碼。從UUID運行代碼時，第一次返回其他代碼，第二次是其他代碼。如何在不改變Java的時間的情況下爲計算機獲取唯一的ID？我使用操作系統Windows。
讓我們這樣說吧：我的每臺機器的程序只給出一個唯一的密鑰。如果我生成uuid並保存它的本地存儲，然後客戶端將複製這個程序與本地存儲，並把它放在另一臺機器，而不是本地密鑰.... – Saahon
