我已经下载了“ jnetpcap-1.4.r1425-1.linux64.x86_64.tgz” dir目录树看起来很像。

我将jar放在我的程序执行所在的bin文件夹中，并将其他.so文件和本机文件夹放在其中。
但我仍然得到
java.lang.UnsatisfiedLinkError: com.slytechs.library.NativeLibrary.dlopen(Ljava/lang/String;)J

然后我想打开罐子，看看它试图加载什么文件。 我发现
package com.slytechs.library;
import java.util.Collection;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
@Library(natives={"Kernel"}, jni={"jnetpcap"})
public class NativeLibrary
所以我的问题是它最初尝试加载哪个文件
@Library（natives = {“ Kernel”}，jni = {“ jnetpcap ”}}）
我怀疑是jnetpcap.so，该文件随软件包一起提供。
在Windows中，我遇到了依赖问题，需要丢失wpcap.dll和packet.dll，因此我将其放置并能够执行。
对于centos，它甚至没有加载库。
如果我做ldd *。*，那么在这里发现了某些依赖性。

我看到很多发布的问题，人们说要更改.so文件名等等。
centos中的解决方案是什么？ 更具体地说，@Library（natives = {“ Kernel”}，jni = {“ jnetpcap”}） 什么是jni = {“ jentpcap”} and natives = {“ Kernel”}
