对象实例与Byte[]之间的转换

主要的类是ObjectOutputStream  ObjectInputStream 和 ByteArrayOutputStream ByteArrayInputStream

对象转Byte[]

  ObjectOutputStream oos = null;
		ByteArrayOutputStream byteOut = null;
		try {
			byteOut = new ByteArrayOutputStream();
			oos = new ObjectOutputStream(byteOut);
			oos.writeObject(obj);
			byte[] bytes = byteOut.toByteArray();	
		} catch (Exception e) {
		}

Byte[]转对象

     ByteArrayInputStream in = null;
		try {
			in = new ByteArrayInputStream(bytes);
			ObjectInputStream objIn = new ObjectInputStream(in);
			Object obj = objIn.readObject();
		} catch (Exception e) {
		}
