java - 如何使用无限的java.util.stream.Stream？

Question

假设我有一个无限的流:

Stream<Socket> stream = Stream.generate(() -> {
    try {
        return serverSocket.accept();
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
});

我希望能够像这样使用它:

stream.forEach(socket -> {
    new Thread(() -> {
        socket.getOutputStream().write("Hi there, client.");
    });
});

但这似乎不起作用，这可能是因为我误解了 Java 8 Streams 的一个关键方面。我做错了什么？

@Andres Riofrio 答案的变体:

stream
  .<Runnable>map(socket -> () ->
    socket
      .getOutputStream()
      .write("Hi there, client.")
  ) // create a Runnable that writes a string to the socket's output stream
  .map(Thread::new) // transform each Runnable into a Thread
  .forEach(Thread::start) // start each Thread
;
