Java zip 文件和目录到一个存档中

Question

我的文件结构如下：

C:/test/example1/file1.txt
C:/test/file2.txt
C:/test/file3.txt

如何归档这些文件和目录，以便生成的 zip 看起来像这样：

Archive.zip
     example
          file1.txt
     file2.txt
     file3.txt

就像 WinRar 在选择多个文件和文件夹进行压缩时所做的那样。

代码：

Path baseDir = Paths.get(content.toString());
Path zipPath = Paths.get(mainJarDir.toString());
Map<String, ?> env = Collections.singletonMap("create", "true");
URI uri = URI.create("jar:" + zipPath.toUri());

try {
  final FileSystem zipfs = FileSystems.newFileSystem(uri, env);
} 
catch (Exception e) {
  e.printStackTrace();
  try {
    MoreFiles.copyRecursive(baseDir, zipfs.get("/"), RecursionMode.FAIL_FAST, StandardCopyOption.REPLACE_EXISTING);
  } 
  catch (Exception ex) {
    ex.printStackTrace();
  }
}

这是使用one of my packages 完成的：

final Path baseDir = Paths.get("c:\\test");

final Path zipPath = Paths.get("path/to/zipfile");
final Map<String, ?> env = Collections.singletonMap("create", "true");
final URI uri = URI.create("jar:" + zipPath.toUri());

try (
    final FileSystem zipfs = FileSystems.newFileSystem(uri, env);
) {
    // in java7-fs-more
    MoreFiles.copyRecursive(baseDir, zipfs.getPath("/"), RecursiveMode.FAIL_FAST);
}
