使用java获取文件夹的挂载点

import java.io.File;

public class MountPointExample {
    public static void main(String[] args) {
        File folder = new File("/path/to/folder");
        String mountPoint = getMountPoint(folder);
        System.out.println("Mount point of folder: " + mountPoint);
    }

    public static String getMountPoint(File folder) {
        String absolutePath = folder.getAbsolutePath();
        File parentFile = folder.getParentFile();

        // Iterate through parent directories until the mount point is found
        while (parentFile != null) {
            if (parentFile.getAbsolutePath().equals(absolutePath)) {
                // Found the mount point
                return absolutePath;
            }

            // Move to the next parent directory
            absolutePath = parentFile.getAbsolutePath();
            parentFile = parentFile.getParentFile();
        }

        return null; // Mount point not found
    }
}
