Features

wamp2spring implements the WAMP basic profile and a meaningful subset of advanced profile features.

Basic profile

Core routing roles:

• dealer for RPC
• broker for publish/subscribe

Core protocol support:

• session establishment through HELLO and WELCOME

• registration, invocation, subscription, publication, and disconnect handling

Advanced dealer features

The current feature model includes support for dealer-side capabilities such as:

• call_canceling
• call_timeout
• progressive_call_results
• progressive_call_invocations
• caller_identification
• pattern_based_registration
• shared_registration
• sharded_registration
• call_reroute
• registration_meta_api
• session_meta_api
• testament_meta_api
• registration_revocation

Advanced broker features

The broker feature model includes:

• subscriber_blackwhite_listing
• publisher_exclusion
• publisher_identification
• pattern_based_subscription
• sharded_subscription
• event_retention
• event_history
• session_meta_api
• subscription_meta_api
• subscription_revocation

Feature defaults

By default every supported feature is enabled when you use the standard @EnableServletWamp, @EnableReactiveWamp, or @EnableServletWampLongpoll configuration.

You can disable features through configureFeatures:

import org.springframework.context.annotation.Configuration;

import ch.rasc.wamp2spring.config.Feature;
import ch.rasc.wamp2spring.config.Features;
import ch.rasc.wamp2spring.servlet.WampServletConfigurer;

@Configuration
public class WampConfiguration implements WampServletConfigurer {

  @Override
  public void configureFeatures(Features features) {
    features.disable(Feature.BROKER_EVENT_RETENTION);
    features.disable(Feature.DEALER);
  }

}

Application-level integration points

Beyond protocol features, the current codebase provides:

• @WampProcedure for binding Spring bean methods to procedures
• @WampListener for binding Spring bean methods to topics
• WampPublisher for server-side publication
• WampAuthorizer for WAMP-level authorization decisions
• WAMP authentication provider SPI for challenge/response and ticket-based authentication
