Java 如果獲取本機(jī)信息 如本機(jī)操作系統(tǒng) IP MAC... - Java / Java...
Map<String, String> map = System.getenv();
String userName = map.get("USERNAME");// 獲取用戶名
String computerName = map.get("COMPUTERNAME");// 獲取計(jì)算機(jī)名
String userDomain = map.get("USERDOMAIN");// 獲取計(jì)算機(jī)域名
System.out.println(userName);
System.out.println(computerName);
System.out.println(userDomain);

********************************************************************************IP地址可以取到，Mac不能直接取到，必須使用JNI或者調(diào)用外部命令
- Java code
Enumeration en = NetworkInterface.getNetworkInterfaces();Set ipList = new HashSet();while (en.hasMoreElements()) {NetworkInterface intf = (NetworkInterface)en.nextElement();Enumeration enAddr = intf.getInetAddresses();while (enAddr.hasMoreElements()) {InetAddress addr = (InetAddress) enAddr.nextElement();ipList.add(addr.getHostAddress());}}
**************************************************************************************
也可以通過cmd命令 然后io輸出得到 如果是Vista系統(tǒng) 要把那個36改改 我記得好像是改成48還是多少
- Java code
import java.io.InputStreamReader;import java.io.BufferedReader;public class macaddress {public static void main(String[] args) {macaddress mdd = new macaddress();String str=mdd.getMacOnWindow();System.out.println(str);}private static String getMacOnWindow() {String s = "";try {String s1 = "ipconfig /all";Process process = Runtime.getRuntime().exec(s1);BufferedReader bufferedreader = new BufferedReader(new InputStreamReader(process.getInputStream()));String nextLine;for (String line = bufferedreader.readLine(); line != null; line = nextLine) {nextLine = bufferedreader.readLine();if (line.indexOf("Physical Address") <= 0) {continue;}int i = line.indexOf("Physical Address") + 36;s = line.substring(i);break;}bufferedreader.close();process.waitFor();} catch (Exception exception) {s = "";}return s.trim();}}
