获取服务器ip地址java

A. java里面如何获取服务器的ip地址，帮帮忙

获取本机ip地址
InetAddress addr = InetAddress.getLocalHost();
ip=addr.getHostAddress().toString;

B. JAVA怎么获取服务器IP

首先IP为一个字符串,例如：
class test{
static void Split(string ip,out string str1)
{
int i=ip.length;
while(i>0)
{
char ch=ip[i-1];
if(ch==':')
break;
i--;
}
str1=ip.Substring(0,i);
}
static void Main()
{
string str1;
Split("192.168.0.255:8080",out str1)
Console.WriteLine("{0}",str1);
}
}
str1中保存的就是你的ip,192.168.0.255

C. JAVA获取IP地址

public static void main(String[] args) { try { // 获取计算机名 String name = InetAddress.getLocalHost().getHostName(); // 获取IP地址 String ip = InetAddress.getLocalHost().getHostAddress(); System.out.println("计算机名："+name); System.out.println("IP地址："+ip); } catch (UnknownHostException e) { System.out.println("异常：" + e); e.printStackTrace(); } }
是否可以解决您的问题？

D. JAVA怎么获取IP地址

java代码获取ip地址方法是
调用java.net包下面的的InetAddress类获取。

E. java编程，获取局域网内服务器端的ip地址

socket.connect(new InetSocketAddress(ip, port), timeout)

看有没有抛异常 没异常就是已经连接上了

想获取服务器名称 可以用ARP协议 或者测试连接的时候服务器回应一个名称

package;

importjava.io.IOException;
importjava.net.InetSocketAddress;
importjava.net.Socket;

publicclassClient{

publicstaticvoidmain(String[]args){
/**
*端口号
*/
intport=10000;
/**
*连接延时
*/
inttimeout=300;
System.out.println("ScannerStart...");
Socketsocket;
/**
*扫描
*/
for(inti=1,k=254;i<k;i++){
if((socket=isOnLine("192.168.1."+i,port,timeout))!=null){
System.out.println("Server:"
+socket.getInetAddress().getHostAddress()
+":"+socket.getPort()+"IsWaiting...");
}

/**
*关闭连接
*/
if(socket!=null&&!socket.isClosed()){
try{
socket.close();
}catch(IOExceptione){
socket=null;
}
}
}
System.out.println("Scannerend...");
}

/**
*测试连接服务器,返回连接成功后的Socket
*
*@paramip
*服务器Ip
*@paramport
*服务器端口号
*@paramtimeout
*连接延时
*@return返回连接成功后的Socket
*/
privatestaticSocketisOnLine(Stringip,intport,inttimeout){
Socketsocket=newSocket();
try{
socket.connect(newInetSocketAddress(ip,port),timeout);
}catch(IOExceptione){
returnnull;
}
returnsocket;
}

}

F. 怎么编写一个Java程序来获取ip地址

import java.util.*;
import java.net.*;public class getMyIP
{
public static void main(String[] args)
{
String IP = null;
String host = null;

try
{
InetAddress ia = InetAddress.getLocalHost();
host = ia.getHostName();//获取计算机名字
IP= ia.getHostAddress();//获取IP
}
catch(UnknownHostException e)
{
e.printStackTrace();
}

System.out.println(host);
System.out.println(IP);
}
}

G. java里,怎么取得IP地址

package A;
import javax.servlet.http.HttpServletRequest;
public class a {
public String getRemortIP(HttpServletRequest request)
{
if (request.getHeader("x-forwarded-for") == null)
{
return request.getRemoteAddr();
}
return request.getHeader("x-forwarded-for");
}
public String getIpAddr(HttpServletRequest request) {
String ip = request.getHeader("x-forwarded-for");
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("Proxy-Client-IP");
}
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("WL-Proxy-Client-IP");
}
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
}
return ip;
}
}
接着有些了个jsp来调用：
<%@ page language="java" import="java.util.*,A.*" pageEncoding="utf-8"%>
<jsp:useBean id="test" class="A.a" scope="request" > </jsp:useBean>
<%
out.println("request.getRemoteAddr(): " + request.getRemoteAddr()); //这里输出的不是真正的ip
test.getIpAddr(); //这里的参数怎么写？
%>

H. java怎么获取ip地址

java获取ip地址
public static void main(String[] args) { try { // 获取计算机名 String name = InetAddress.getLocalHost().getHostName(); // 获取IP地址 String ip = InetAddress.getLocalHost().getHostAddress(); System.out.println("计算机名："+name); System.out.println("IP地址："+ip); } catch (UnknownHostException e) { System.out.println("异常：" + e); e.printStackTrace(); } }

I. java 调用接口获取服务器IP和端口号

<%=
request.getservername()%>
服务器的域名
<%=
java.net.inetaddress.getlocalhost().gethostaddress()
%>
服务器的ip地址
<%=request.getserverport()%>
服务器正在运行的端口

J. java 调用接口获取服务器IP和端口号

package test5;
public interface A {
void setAll(int ID,String IP);
String getAll();
}
package test5;
public class B implements A{
String IP;
int ID;
public void setAll(int ID,String IP) {
this.ID=ID;
this.IP=IP;
}
public String getAll() {
return "ID为: "+ID+"\t\t"+"IP为: "+IP;
}
public static void main(String[] args) {
B b=new B();
b.setAll(1, "192.168.1.1");
System.out.println(b.getAll());
}
}
