在Java 中,可以使用标准的网络库来获取本机的 IP 地址和主机名。以下实例演示了如何使用 InetAddress 类的 getLocalHost 和 getLocalAddress() 方法获取本机主机名及 ip 地址:Main.java 文件 import java.net.InetAddress; import java.net.UnknownHostException; public class NetworkInfo { public static void main...
一、Java获取IP地址 首先使用基于Spring Boot搭建项目，在controller添加HttpServletRequest请求参数：@RestControllerpublic class IpController { @GetMapping("/ip-address")public String ipAddress(HttpServletRequest request) { // 接收request 通过HttpServletRequest获取IP地址：String ip = request.getHeader("x-...
以下是一个简单的Servlet示例,演示如何获取GET请求的IP地址: @WebServlet("/example")publicclassExampleServletextendsHttpServlet{protectedvoiddoGet(HttpServletRequestrequest,HttpServletResponseresponse)throwsServletException,IOException{StringipAddress=request.getRemoteAddr();response.getWriter().println("Your IP addre...
方法一:使用InetAddress类 Java中的InetAddress类提供了用于处理IP地址和域名的方法。我们可以使用该类来获取eth0的IP地址。下面是一个示例代码: importjava.net.InetAddress;importjava.net.NetworkInterface;importjava.net.SocketException;importjava.util.Enumeration;publicclassGetIPAddress{publicstaticvoidmain(String[...
publicList<String>getLocalIps(){try{List<String>ipList=newArrayList<>();Enumeration<NetworkInterface>networkInterfaces=NetworkInterface.getNetworkInterfaces();while(networkInterfaces.hasMoreElements()){NetworkInterface networkInterface=networkInterfaces.nextElement();Enumeration<InetAddress>inetAddresses=networkInterfa...
for (InetAddress address : addresses) { String ipAddress = address.getHostAddress(); System.out.println(ipAddress); } 如果需要获取本机的IP地址,可以使用getLocalHost()方法,代码如下: InetAddress localAddress = InetAddress.getLocalHost(); String ipAddress = localAddress.getHostAddress(); ...
getHostAddress为byte数组，getAddress是个String字符串。所以，getAddress方便展示，getHostAddress方便作为数据进行处理。肯定
