I have a task to create a Spring-integration TCP client which should connect to a server and receive messages from it:
- The server is responsible for sending "heartbeat" and data messages and doesn't expect any incoming messages from the client, except acknowledgements.
- The client must open and maintain (reopen) a connection to the server.
As I understand, TcpNetClientConnectionFactory opens a connection only upon sending a message. Is there any way to open a connection without sending any data (something like SocketFactory.createSocket(host, port) does) and maintain it?
