Controllers implementing SwaggerController needs to implement dsl.

[mani199184]

dsl can be implemented with line "override protected val dsl = self"

My controllers are trying to extend SwaggerController without dependency injections. I am creating objects of controllers with swagger parameter. Like class mycontroller(s: Swagger) extends SwaggerController { override implicit protected val swagger = s ... }

I am getting error "class mycontroller needs to be abstract, since value dsl in trait SwaggerRouteDSL of type com.twitter.finatra.http.RouteDSL is not defined"

I havent figured out how to create a SwaggerController without injecting the Swagger/OpenAPI object. This is because the object is created in your project via Module with the information you want to show in your documentation page.

Happy to accept any pull requests to make this more streamlined.

Can't we use this finantra-swagger without dependecy injection? I created an object of swagger module and used it in mycontroller. Can I use it like below code? If yes, why I am getting error "class mycontroller needs to be abstract, since value dsl in trait SwaggerRouteDSL of type com.twitter.finatra.http.RouteDSL is not defined"

Swagger module:

`lazy val myswagger : Swagger = {
    val swagger = new Swagger()
    val info = new Info()
      .title("API")
      .description(
        """ test
      """.stripMargin)
      .version("1.0")

    swagger
      .info(info)
      .addProduces("application/json")

    swagger.addConsumes("application/json")
    swagger
  }`

My controller

class mycontroller(s: Swagger) extends SwaggerController { override implicit protected val swagger = s ... } http server

`class MyHttpServer()
  extends HttpServer {
  override def jacksonModule = CustomJacksonModule

  override protected def configureHttp(router: HttpRouter): Unit = {
    router.add[DocsController]
    router.add(new  mycontroller(myswagger))
  }

  /**
    * Set it to 32KB solves the problem
    * @param server
    * @return
    */
  override protected def configureHttpServer(server: Http.Server) = {
    super.configureHttpServer(server)
      .configured(http.param.MaxHeaderSize(32.kilobytes))
  }
}`

I think one of the concepts with Finatra is that it uses a lot of injection, which is why this module is this way.
