我正在尝试使用该jnetpcap库编写一个数据包捕获 java 程序。但我想知道是否可以从给定端口获取 PID？就我而言，我正在尝试使用 Sigar API 来获取 PID（方法名称是getProcPort(protocol, port)）。

PcapPacketHandler<String> jpacketHandler = new PcapPacketHandler<String>(){
    public void nextPacket(PcapPacket packet, String user) {
        Tcp tcp = new Tcp();
        Ip4 ip = new Ip4();
        String protocol;
        long port;
        if(packet.hasHeader(ip)&&packet.hasHeader(tcp)){
            protocol = tcp.getName();
            port = tcp.source();
            try {
                //but the following line will cause an error 
                long pid = sigar.getProcPort("tcp", Long.toString(port));
                System.out.println("pid : " + pid);
            } catch (SigarException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            if(filtering==false){
                printPacketResult(packet, tcp, ip, port, protocol);
            }else if(filtering==true){
                filteredPrintPacketResult(packet, tcp, ip, port, protocol);
            }

        }                   
    }
};

我得到的错误是：

org.hyperic.sigar.SigarNotImplementedException：此方法尚未在 org.hyperic.sigar.SigarNotImplementedException.(SigarNotImplementedException.java:28) 在 org.hyperic.sigar.Sigar.getProcPort(Native Method) 的此平台上实现。 hyperic.sigar.Sigar.getProcPort(Sigar.java:632) at networkInfo.PackageCapture$1.nextPacket(PackageCapture.java:84) at networkInfo.PackageCapture$1.nextPacket(PackageCapture.java:1) at org.jnetpcap.Pcap.loop (Native Method) at org.jnetpcap.Pcap.loop(Unknown Source) at networkInfo.PackageCapture.startNet(PackageCapture.java:111) at networkInfo.FilterChoice.choice(FilterChoice.java:27) at networkInfo.Main.main(Main .java:6)

有可能吗？如果你有一些信息，请给我一些提示。
