获取本机ip地址
InetAddress addr = InetAddressgetLocalHost();
ip=addrgetHostAddress()toString;
public static void main(String[] args) {
try {
Systemoutprintln("当前时间:"+new Date());
Systemoutprintln("IP地址 : " + InetAddressgetLocalHost());
} catch (UnknownHostException e) {
eprintStackTrace();
}
}
1得到局域网网段,可由自己机器的IP来确定 (也可以手动获取主机IP-CMD-ipconfig /all)
2根据IP类型,一次遍历局域网内IP地址
JAVA类,编译之后直接运行便可以得到局域网内所有IP,具体怎样使用你自己编写相应代码调用便可
代码如下::
package bean;
import javaio;
import javautil;
public class Ip{
static public HashMap ping; //ping 后的结果集
public HashMap getPing(){ //用来得到ping后的结果集
return ping;
}
//当前线程的数量, 防止过多线程摧毁电脑
static int threadCount = 0;
public Ip() {
ping = new HashMap();
}
public void Ping(String ip) throws Exception{
//最多30个线程
while(threadCount>30)
Threadsleep(50);
threadCount +=1;
PingIp p = new PingIp(ip);
pstart();
}
public void PingAll() throws Exception{
//首先得到本机的IP,得到网段
InetAddress host = InetAddressgetLocalHost();
String hostAddress = hostgetHostAddress();
int k=0;
k=hostAddresslastIndexOf("");
String ss = hostAddresssubstring(0,k+1);
for(int i=1;i <=255;i++){ //对所有局域网Ip
String iip=ss+i;
Ping(iip);
}
//等着所有Ping结束
while(threadCount>0)
Threadsleep(50);
}
public static void main(String[] args) throws Exception{
Ip ip= new Ip();
ipPingAll();
javautilSet entries = pingentrySet();
Iterator iter=entriesiterator();
String k;
while(iterhasNext()){
MapEntry entry=(MapEntry)iternext();
String key=(String)entrygetKey();
String value=(String)entrygetValue();
if(valueequals("true"))
Systemoutprintln(key+"-->"+value);
}
}
class PingIp extends Thread{
public String ip; // IP
public PingIp(String ip){
thisip=ip;
}
public void run(){
try{
Process p= RuntimegetRuntime()exec ("ping "+ip+ " -w 300 -n 1");
InputStreamReader ir = new InputStreamReader(pgetInputStream());
LineNumberReader input = new LineNumberReader (ir);
//读取结果行
for (int i=1 ; i <7; i++)
inputreadLine();
String line= inputreadLine();
if (linelength() <17 || linesubstring(8,17)equals("timed out"))
pingput(ip,"false");
else
pingput(ip,"true");
//线程结束
threadCount -= 1;
}catch (IOException e){}
}
}
}
public static String getHostIpAddress() {
String hostIp = "";
InetAddress netAddress = getInetAddress();
hostIp = getHostIp(netAddress);
return hostIp;
}
public static InetAddress getInetAddress() {
try {
return InetAddressgetLocalHost();
} catch (UnknownHostException e) {
Systemoutprintln("unknown host!");
}
return null;
}
public static String getHostIp(InetAddress netAddress) {
if (null == netAddress) {
return null;
}
String ip = netAddressgetHostAddress(); // get the ip address
return ip;
}
public static String getHostName(InetAddress netAddress) {
if (null == netAddress) {
return null;
}
String name = netAddressgetHostName(); // get the host address
return name;
}
为适应不同的网络情况,提供这个类:看下面的代码吧,Copy过去就能用。
import javaxservlet>
