Tutorial
A simple try
Java native API:
You can use: NetworkInterface to obtain computing network interface information (the following figure traverses all network interfaces)
Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
while (interfaces.hasMoreElements()) {
NetworkInterface networkInterface = interfaces.nextElement();
Enumeration<InetAddress> addresses = networkInterface.getInetAddresses();
while (addresses.hasMoreElements()) {
InetAddress address = addresses.nextElement();
// if (!address.isLoopbackAddress() & amp; & amp; address.isSiteLocalAddress()) {
console.info(networkInterface.getInterfaceAddresses());
console.Info(networkInterface.getInterfaceAddresses());
// }
}
}
Comparison
This method of acquisition is not necessarily accurate. There are several influencing factors:
Permissions: In some operating systems, obtaining information about a network interface may require special permissions. Without these permissions, it may not be possible to obtain all network interface information.
Virtual and hidden network interfaces: Some systems may have virtual network interfaces or hidden network interfaces, which may not be returned by
NetworkInterface.getNetworkInterfaces().Java security policy: If your Java program runs in an environment with a security manager, you may need
NetPermission("getNetworkInformation")permission to obtain the network Interface information. Otherwise,NetworkInterface.getNetworkInterfaces()may simply return an emptyEnumeration.Network interface status: If network interfaces are in an inactive state, such as not connected to the network, they may not be returned by
NetworkInterface.getNetworkInterfaces().
Start acquisition in C++ native way
So I started to get it from the data API provided by the Windows operating system and wrote it as a Java plug-in
And when it was written, these filtering methods were provided in Java – applicable to all network cards (valid for personal testing) (JDK19 x64)
ip_if_filter: quoted from ipifcons.h
family: quoted from ws2def.h
Can be mixed with the JNAudio text-to-speech plug-in (free x64) I wrote last time
Some data of all network cards obtained by using this plug-in, You can try to use filtering to distinguish wifi and Ethernet
The information, filtering method constant referencedipifcons.h AND ws2def.h can be directly Baidu.

colorful1.2 Framework
Because these frameworks are separate modular plug-ins integrated in colorful1.2, you need to install the colorful1.2 framework first
Framework installation tutorial/usage tutorial, I will plan to separate some modules of colorful1.2 later and make them into some independent plug-ins
Tutorial
Basic instantiation
//You need to import the location of this plug-in dll library first
System.load("Net_Work_Route.dll");
//Instance Java object
net_work C=new net_work();
//C++ binds net_work to the Java instance object
C.initModel();
//C.Method
//After unbinding/releasing/releasing, you will not be able to use any method in net_work and you need to re-initModel.
C.release_network();
How to use list
<strong>initModel</strong> |
Bind C++ methods/classes/other references to Java instantiated objects in the plug-in You can think of it as the initial method, you need to use it <strong>release_network (unbinding) release</strong> |
<strong>getLocalAdapter</strong> |
Get the names of all local network card adapters. After obtaining them, you can get some information about them based on these names, such as: IP4 address return (List |
<strong>getAdapterAddress</strong> |
Parameter String, adapter name, you can use
<strong>ws2def.adapter_null Gets the IP4 return List<String></strong> of all network card adapter conversations |
<strong> getSubnetMask</strong> |
Parameter String, adapter name, you can use
<strong>ws2def.adapter_null to get the subnet mask of all network card adapter conversations Code returns List<String></strong> |
<strong>getLocalHostIP4</strong> |
Parameter int, you need to cooperate
<strong>ip_if_filter.* filters wifi/Ethernet/default gateway/other ip, returns List<String>< for all IPs of all network card adapters for ip_if_filter.NULL /strong> |
<strong>getLocalHostMac</strong> |
Parameter int, you Need to cooperate
<strong>ip_if_filter.* Filters wifi/Ethernet/default gateway/other MAC, returns List<String></strong> for all MACs of all network card adapters for ip_if_filter.NULL |
<strong>getLocalHostIP6</strong> |
Parameter int, you need to match <strong>ws2def.* Filter wifi/Ethernet/default gateway/other IP6, (all network cards), return List<String></strong> |
<strong>getDeviceInfo</strong> |
<strong>Host address type: 0 Address List:1 Alias:2 Address length: 3 Formal hostname: 4</strong> Return List |
<strong>getDeviceName</strong> |
Returns the name of the current system of the current device Return String |
<strong>release_network</strong> |
(Unbinding) Release, you will not be able to use/find the bound Class/function/other references, and call other methods again after use NULL will be returned and no error will be raised. You need to use initModel to rebind |
<strong>getWebStormInfo</strong> |
Obtain web host information through the Internet through a valid IP/domain name <strong>Host address type: 0 Address List:1 Alias:2 Address length: 3 Formal hostname: 4 Return List<String></strong> After multiple attempts, the other party may reject and return Null |
<strong>get_gateway</strong> |
Get the current default gateway IP strong> |
A simple short try
System.load("Net_Work_Route.dll path");
net_work C=new net_work();
C.initModel();
List<String> ip_if=C.getAdapterAddress(ws2def.adapter_null);
console.info(ip_if);
List<String> device = C.getDeviceInfo();
console.info("""
Host address type: %s
Address list: %s
Alias: %s
Address length: %s
Formal host name: %s""".formatted(device.get(0), device.get(1), device.get(2), device.get(3), device.get(4) ));
List<String> adapter = C.getLocalAdapter(ip_if_filter.NULL);
console.info("All network adapters::%s".formatted(adapter.toString()));
console.info("Current default IP forwarding table default gateway: %s".formatted(C.get_gateway()));
console.info("The current IP forwarded by all network cards: %s".formatted(C.getLocalHostIP4(ip_if_filter.NULL)));
console.info("All IPs of all current network card adapters:%s".formatted(C.getAdapterAddress(ws2def.adapter_null)));
console.info("Current subnet mask of all network card adapters: %s".formatted(C.getSubnetMask(ws2def.adapter_null)));
console.info("Currently all network card adapter UDP, TCP, etc forwarding objects: %s".formatted(C.getLocalHostIP4(ws2def.AF_INET)));
C.release_network();
