一、Java类直接获取IP、Mac地址：
import java.io.IOException;import java.io.InputStreamReader;
import java.io.LineNumberReader;
import java.net.InetAddress;
import java.net.UnknownHostException;
public class Dos {
/**
* @param args
* @throws IOException
* @throws InterruptedException
*/
public static void main(String[] args) throws IOException, InterruptedException {
Dos test =new Dos();
System.out.println(test.getIP());
System.out.println(test.getHostName());
System.out.println("mak="+test.getMACAddressByIp("10.66.81.63"));
}
public String getIP(){
InetAddress inet;
try {
inet = InetAddress.getLocalHost();
InetAddress.getByName("");
return inet.getHostAddress();
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "";
}
public String getHostName(){
InetAddress inet;
try {
inet = InetAddress.getLocalHost();
InetAddress.getByName("");
return inet.getHostName();
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "";
}
//ip必须是真实的ip，如：10.66.204.44，而不能是127.0.0.1或localhsot，否则返回"".可以指定可ping通的所有计算机的IP。
public String getMACAddressByIp(String ip){
String str = "";
String macAddress = "";
try {
Process p = Runtime.getRuntime().exec("nbtstat -A " + ip);
InputStreamReader ir = new InputStreamReader(p.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) {
macAddress = str.substring(str.indexOf("MAC Address") + 14, str.length());
break;
}
}
}
} catch (IOException e) {
e.printStackTrace(System.out);
}
return macAddress;
}
}
/**
* 直接获取mac地址（何伟）
* @return
*/
private static String getMACAddress()
{
String address = "";
String os = System.getProperty("os.name");
if ((os != null) && (os.startsWith("Windows")))
try
{
String line;
String command = "cmd.exe /c ipconfig /all";
Process p = Runtime.getRuntime().exec(command);
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
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 localIOException) {
}
return address;
}
二、web项目获取服务器端IP及客户端IP
String LocalAddr = request.getLocalAddr();//127.0.0.1
String LocalName = request.getLocalName();//localhsot
String test2 = "getRemoteHost="+request.getRemoteHost()+";getRemotePort="+request.getRemotePort()+";getRemoteUser="+request.getRemoteUser()+";getRemoteAddr="+request.getRemoteAddr();
System.out.println(test2);
String RemoteAddr = request.getRemoteAddr();
System.out.println(getRemoteAddress(request));
request.getSession().setAttribute("LocalAddr", LocalAddr);
request.getSession().setAttribute("LocalName", LocalName);
request.getSession().setAttribute("test2", test2);
request.getSession().setAttribute("RemoteAddr", RemoteAddr);
request.getRequestDispatcher("test.jsp").forward(request, response);
