推荐答案

将其添加到程序的开头:

Add this to the beginning of your program:

System.out.println(System.getProperty("java.library.path"));

您应该获得目录列表.您的jpcap的DLL(在UNIX上为so)必须位于这些目录之一中，以便程序正常运行.如果不存在，则可以:

You should get a list of directories. Your jpcap's DLL (or so on UNIX) must be in one of these directories in order for your program to work. If it is not there, then either:

• 将包含该DLL/so的目录添加到系统的PATH(首选).
• 将DLL/so添加到打印的目录之一.

• Add the directory containing that DLL/so to your system's PATH (preferred).
• Add the DLL/so into one of the directories printed.
