Class ApiListener

org.frankframework.http.PushingListenerAdapter
org.frankframework.http.rest.ApiListener
All Implemented Interfaces:
HasPhysicalDestination, IConfigurable, IConfigurationAware, IListener<Message>, INamedObject, IPushingListener<Message>, IScopeProvider, ReceiverAware<String>, ServiceClient, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

public class ApiListener extends PushingListenerAdapter implements HasPhysicalDestination, ReceiverAware<String>
Listener that allows a Receiver to receive messages as a REST webservice. Prepends the configured URI pattern with api/. The structure of REST messages is described by OpenAPI specifications. The Frank!Framework generates an OpenAPI specification for each ApiListener and for all ApiListeners in all configurations combined. You can find them in the Frank!Console under main menu item Webservices, heading Available ApiListeners.

The generated OpenAPI specifications have servers and paths objects and therefore they document the full URLs of the provided services.

It is possible to automatically generate eTags over the listener result. This can be controlled by globally setting the property api.etag.enabled or by setting the attribute updateEtag="true". When enabled the listener will respond to the If-Match, If-None-Match headers and may return status code 304.

In order to enable eTags for multiple nodes you must configure Memcached to store the eTags. The following properties will need to be set:

  • etag.cache.server=ip or hostname:port
  • etag.cache.type=memcached
In case authentication, is required the following application properties can be used:
  • etag.cache.username
  • etag.cache.password
  • etag.cache.authalias

      Returns:
      null if no pattern is found
    • isConsumable

      public boolean isConsumable(@Nullable String contentType)
      Match request 'Content-Type' (eg. on POST) to consumes enum to see if the listener accepts the message
