Hessian AMQP

Hessian AMQP is a component helping the deployment of Hessian services using an AMQP server as the underlying transport. The principle is almost identical to Hessian services over HTTP:

1. Create an interface defining the methods exposed:

public interface EchoService {
    String echo(String message);
}

2. Implement the interface:

public class EchoServiceImpl implements EchoService {
    
    public String echo(String message) {
        return message;
    }
}

3. Deploy an endpoint for the service and attach it to an AMQP connection:

HessianEndpoint endpoint = new HessianEndpoint(new EchoServiceImpl());
endpoint.run(connection);

4. On the client side, create a proxy of the interface:

AMQPHessianProxyFactory factory = new AMQPHessianProxyFactory();
EchoService service = factory.create(EchoService.class, "amqp://user:pwd@example.com/test");

5. The service is ready to be consumed!

String echo = service.echo("Hello Hessian!");
