我正在使用 IntelliJ 运行示例 java-jnetpcap 应用程序。我在类路径中有 64 位 JDK，并包含以下依赖项
<dependency>
<groupId>jnetpcap</groupId>
<artifactId>jnetpcap</artifactId>
<version>1.4.r1425-1f</version>
</dependency>
我正在运行下面的 sample.java 类
public class PcapReaderDemo
{
private static final String filePath= "/src/main/resources/TAPcapture.pcap";
public static void main(String [] arguments){
final StringBuilder errbuf = new StringBuilder();
Pcap pcap = Pcap.openOffline(filePath,errbuf);
if (pcap == null) {
System.err.printf("Error while opening device for capture: "
+ errbuf.toString());
return;
}
PcapPacketHandler<String> jpacketHandler = new PcapPacketHandler<String>() {
public void nextPacket(PcapPacket packet, String user) {
System.out.printf("Received at %s caplen=%-4d len=%-4d %s\n",
new Date(packet.getCaptureHeader().timestampInMillis()),
packet.getCaptureHeader().caplen(), // Length actually captured
packet.getCaptureHeader().wirelen(), // Original length
user // User supplied object
);
}
};
System.out.println("Cleared");
}
}
它抛出以下异常：
