使用java中的PipedStream将ZipOutputStream转换为ZipInputStream

Question

我想使用PipedOutputStream和PipedInputStream将ZipOutputStream转换为ZipInputStream。我从DataHandler接收ZipOutputStream，我不想在文件上写它然后打开并读取它，而是我想将这个ZipOutputStream转换为ZipInputStream以供我进一步处理，比如提取ZipEntry并将其保存在某个文件中。 / p>

public String documentReceived(@WebParam(name = "document")final DataHandler dataHandler) {
...
   ZipOutputStream zout = new ZipOutputStream(dataHandler.getOutputStream());

   final PipedInputStream pin = new PipedInputStream();
   final PipedOutputStream pout = new PipedOutputStream(pin);

   ??? need help here to convert a ZipOutputStream into
   ??? ZipInputStream

...
}

任何帮助将不胜感激...谢谢
