java如何监听路由器

在Java中监听路由器通常意味着你需要监听网络事件或路由表的变化。以下是一些方法来实现这一功能：

1. 使用Java的`NetworkInterface`和`InetAddress`类

你可以使用`NetworkInterface`和`InetAddress`类来监听网络接口的变化。

```java

import java.net.NetworkInterface;

import java.net.SocketException;

import java.net.InetAddress;

import java.util.Enumeration;

public class NetworkListener {

public static void main(String[] args) {

try {

Enumeration interfaces = NetworkInterface.getNetworkInterfaces();

while (interfaces.hasMoreElements()) {

NetworkInterface networkInterface = interfaces.nextElement();

System.out.println("Interface: " + networkInterface.getName());

Enumeration addresses = networkInterface.getInetAddresses();

while (addresses.hasMoreElements()) {

InetAddress address = addresses.nextElement();

System.out.println("Address: " + address.getHostAddress());
