Enable Scala

To enable using Scala, add the following:

		<dependency>
			<groupId>net.officefloor.scala</groupId>
			<artifactId>officescala</artifactId>
		</dependency>
		<dependency>
			<groupId>net.officefloor.scala</groupId>
			<artifactId>officescalatest</artifactId>
			<scope>test</scope>
		</dependency>

Scala

The Scala to service the request is:

package net.officefloor.tutorial.scalahttpserver

import net.officefloor.web.ObjectResponse

object ScalaService {

  def service(request: ScalaRequest, response: ObjectResponse[ScalaResponse]) {
    response.send(new ScalaResponse(s"Hello ${request.message}"))
  }
}

REST Endpoint

The REST endpoint routing POST requests to '/scala' to the Scala function is configured as follows:

service:
  class: net.officefloor.tutorial.scalahttpserver.ScalaService

Scala Classes

As part of supporting Scala, the necessary Jackson support is included to enable sending/receiving Scala classes as JSON.

The request / response data classes are as follows:

@HttpObject
class ScalaRequest(val message: String)

class ScalaResponse(val message: String)

Testing

WoOF is integrated with ScalaTest via traits. This allows the following ease of testing:

package net.officefloor.tutorial.scalahttpserver

import net.officefloor.scalatest.WoofRules
import org.scalatest.flatspec.AnyFlatSpec

class ScalaHttpServerTest extends AnyFlatSpec with WoofRules {

  "Call Server" should "get result" in {
    withMockWoofServer { server =>
      val request = mockRequest("/scala")
          .method(httpMethod("POST"))
          .header("Content-Type", "application/json")
          .entity(jsonEntity(new ScalaRequest("Daniel")))
      val response = server.send(request)
      response.assertResponse(200, jsonEntity(new ScalaResponse("Hello Daniel")))
    }
  }

}
