如何获取JAR中包含的类路径目录中的文件列表？

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Enumeration;
import java.util.List;
import java.util.jar.JarEntry;
import java.util.jar.JarFile;

public class JarFileUtils {
    public static List<String> getFilesInClasspathDirectory(String jarPath, String classpathDirectory) throws IOException {
        List<String> fileList = new ArrayList<>();

        try (JarFile jarFile = new JarFile(jarPath)) {
            Enumeration<JarEntry> entries = jarFile.entries();
            while (entries.hasMoreElements()) {
                JarEntry entry = entries.nextElement();
                String entryName = entry.getName();

                if (entryName.startsWith(classpathDirectory) && !entry.isDirectory()) {
                    fileList.add(entryName);
                }
            }
        }

        return fileList;
    }

    public static void main(String[] args) {
        String jarPath = "path/to/your/jar/file.jar";
        String classpathDirectory = "your/classpath/directory/";

        try {
            List<String> fileList = getFilesInClasspathDirectory(jarPath, classpathDirectory);
            for (String file : fileList) {
                System.out.println(file);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
