这适用于Java 8：

        try {
            URL  url = new URL("http://cnn.com"); /* Tested on a real URL */
            URLConnection urlc = url.openConnection();
urlc.setDoOutput(true); /* Added this ... */
            OutputStream os = urlc.getOutputStream();
            OutputStream buffer = new BufferedOutputStream(os);
            ObjectOutput output = new ObjectOutputStream(buffer);
            output.writeChars("hello");
            buffer.close();
            os.close();
            output.close();
            System.out.println("Done");
        } catch (IOException e) {
            e.printStackTrace();
        }
