将 Java 对象转成字节数组，java数组,public stati

public static byte[] convertToByteArray(Object obj) throws IOException  {    ObjectOutputStream os = null;    ByteArrayOutputStream byteStream = new ByteArrayOutputStream(5000);    os = new ObjectOutputStream(new BufferedOutputStream(byteStream));    os.flush();    os.writeObject(obj);    os.flush();    byte[] sendBuf = byteStream.toByteArray();    os.close();    return sendBuf;}//该片段来自于http://byrx.net
