Question

尝试使用jpcap捕获数据包。但由于某种原因，我的代码不会打印出包。只能是设备。我不明白为什么它不起作用。

import jpcap.PacketReceiver;
import jpcap.JpcapCaptor;
import jpcap.NetworkInterface;
import jpcap.packet.Packet;
import jpcap.*;

public class JpcapTip implements PacketReceiver {
    public void receivePacket(Packet packet){
       System.out.println(packet);
      //  System.out.println(packet.toString());
    }

    public static void main(String[] args) throws java.io.IOException{
        NetworkInterface[] devices =  JpcapCaptor.getDeviceList();

        for (int i = 0; i < devices.length; i++) {
            System.out.println(devices[i].description); // devices[0]

        }

        NetworkInterface deviceName = devices[0];

        JpcapCaptor  jpcap = JpcapCaptor.openDevice(devices[0], 1028, false, 1);
        jpcap.loopPacket(-1, new JpcapTip());

        //
   }
}

我的编译器输出.-

run:
Microsoft
Qualcomm Atheros Ar81xx series PCI-E Ethernet Controller
Microsoft
java.lang.NoSuchMethodError: setRoutingOption
    at jpcap.JpcapCaptor.nativeOpenLive(Native Method)
    at jpcap.JpcapCaptor.openDevice(JpcapCaptor.java:68)
    at JpcapTip.main(JpcapTip.java:23)

jpcap没有打印出包
