StandaloneLagomClientFactory

abstract class StandaloneLagomClientFactory extends LagomClientFactory

Convenience for constructing service clients in a non Lagom server application.

A StandaloneLagomClientFactory should be used only if your application does NOT have its own akka.actor.ActorSystem, in which this standalone factory will create and manage an akka.actor.ActorSystem and Akka Streams akka.stream.Materializer.

It is important to invoke StandaloneLagomClientFactory#stop() when the application is no longer needed, as this will trigger the shutdown of the underlying akka.actor.ActorSystem and Akka Streams akka.stream.Materializer releasing all thread and connection pools in use by the clients.

There is one more component that you’ll need to provide when creating a client application, that is a service locator. It is up to you what service locator you use, it could be a third party service locator, or a service locator created from static configuration.

Lagom provides a number of built-in service locators, including a StaticServiceLocator, a RoundRobinServiceLocator and a ConfigurationServiceLocator. The easiest way to use these is to mix in their respective Components traits.

For example, here’s a client application built using the static service locator, which uses a static URI:

import java.net.URI
import com.lightbend.lagom.scaladsl.client._
import play.api.libs.ws.ahc.AhcWSComponents

val clientApplication = new StandaloneLagomClientFactory("my-client")
  with StaticServiceLocatorComponents
  with AhcWSComponents {

  override def staticServiceUri = URI.create("http://localhost:8080")
}

Instance Constructors

  1. new StandaloneLagomClientFactory(clientName: String, classLoader: ClassLoader = ...)

    clientName

    The name of the service that is consuming the Lagom service. This will impact how calls made through clients generated by this factory will identify themselves.

    classLoader

    A classloader, it will be used to create the service proxy and needs to have the API for the client in it.

  41. def topicPublisherName: Option[String]

    The name of the topic publisher.

    The name of the topic publisher.

    Since topic publishers don't actually provide any components, they just consume a LagomServer and publish the topics they find there, this can be used to signal that a topic publisher has been provided to publish topics, so that the LagomServerComponents can detect a misconfiguration where one hasn't been provided.

    returns

    The name of the topic publisher that has published topics, if one has been provided.
