在OutputStream上阻止写操作

Question

Communication between two servers:

Server 1 sends a request to Server 2 Server 2 writes response on the stream by using below api

ObjectOutputStream oos = new ObjectOutputStream(servResp.getOutputStream());
oos.writeObject(dataObj)

When server 1 receives the data as

InputStream res = connection.getInputStream();
if(res.available() > 0) {
    ObjectInputStream ois = new ObjectInputStream(res);
    Object object = ois.readObject();
    dataObj = (DataObject)object;
}

Here, res.isavailable() returns zero bytes, It will be resolved by using blocking read on Server 2, But Is there any way to handle it on Server 1?

Answer 1

Any implementation of available() is free to return zero, and there is nothing in the Javadoc about it returning the number of bytes in the stream: on the contrary, there is a specific denial that it does any such thing. Your receiver should just block in readObject() . There is nothing that the sender can do to help other than send.
