Mina 使用ProtoBuffer 序列化出了点问题。有高手请进。万急....

public class MinaClientHanlder extends IoHandlerAdapter {

	public void sessionOpened(IoSession session) throws Exception {

	    System.out.println("sessionOpened");

	    OpRequest.Builder builder = OpRequest.newBuilder();

	    builder.setMsg("1111111");

	    OpRequest request = builder.build();

	    byte[]data =  request.toByteArray();

	    ByteBuffer buffer = ByteBuffer.wrap(data);

	    session.write(getObject(buffer));

	}

	public Object getObject(ByteBuffer byteBuffer) throws IOException, ClassNotFoundException

	{

		IoBuffer buffer = IoBuffer.allocate(byteBuffer.capacity()).setAutoExpand(true);

		for(int i=0; i<byteBuffer.capacity();i++)

		{

			byteBuffer.position(i);

			buffer.put(byteBuffer.get());

		}

		buffer.position(0);

		InputStream input =  buffer.asInputStream();

		ObjectInputStream oi = new ObjectInputStream(input);

		Object obj = oi.readObject();

		input.close();

		oi.close();

		return obj;		

	}
