Java:递归地将文件添加到zip文件但没有完整路径

我试图将文件从zip文件中的文件夹中放入以下结构:

Folder structure:

myFolder
 |-file1.txt
 |-file2.txt
 |-folder172
    |-file817.txt
    |-file818.txt
 ...

Supposed structure inside ZipFile:

file1.txt
file2.txt
folder172
 |-file817.txt
 |-file818.txt

这是我的代码:

public static void writeZip(String path) throws IOException{

    FileOutputStream fos = new FileOutputStream(path+File.separator+"atest.zip");
    ZipOutputStream zos = new ZipOutputStream(fos);

    try {
        Files.walk(Paths.get(path)).filter(Files::isRegularFile).forEach((string) -> addToZipFile(string.toString(),zos));
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    zos.close();
    fos.close();



}


public static void addToZipFile(String fileName, ZipOutputStream zos) throws IOException {

    System.out.println("Writing '" + fileName + "' to zip file");

    File file = new File(fileName);
    FileInputStream fis = null;

    fis = new FileInputStream(file);

    ZipEntry zipEntry = new ZipEntry(fileName);

    zos.putNextEntry(zipEntry);


    byte[] bytes = new byte[1024];
    int length;

    while ((length = fis.read(bytes)) >= 0) {
        zos.write(bytes, 0, length);
    }
    zos.closeEntry();
    fis.close();

}

现在的问题是,当我打电话时writeZip("/home/arthur/.grutil/");,我在zip文件中得到以下结构:

home
 |-arthur
    |-.grutil
       |-file1.txt
       |-file2.txt
       |-folder172
          |-file817.txt
          |-file818.txt
   ...

我如何更改我的代码以获得所谓的结构(如上所述)而不是具有完整路径'/home/arthur/.grutil/ ...'的结构？
