  • package inject

    Play's runtime dependency injection abstraction.

    Play's runtime dependency injection abstraction.

    Play's runtime dependency injection support is built on JSR-330, which provides a specification for declaring how dependencies get wired to components. JSR-330 however does not address how components are provided to or located by a DI container. Play's API seeks to address this in a DI container agnostic way.

    The reason for providing this abstraction is so that Play, the modules it provides, and third party modules can all express their bindings in a way that is not specific to any one DI container.

    Components are bound in the DI container. Each binding is identified by a BindingKey, which is typically an interface that the component implements, and may be optionally qualified by a JSR-330 qualifier annotation. A binding key is bound to a BindingTarget, which describes how the implementation of the interface that the binding key represents is constructed or provided. Bindings may also be scoped using JSR-330 scope annotations.

    Bindings are provided by instances of Module.

    Out of the box, Play provides an implementation of this abstraction using Guice.

  4. abstract def httpFilters: Seq[EssentialFilter]

    List of filters, typically provided by mixing in play.filters.HttpFiltersComponents or play.api.NoHttpFiltersComponents.

    List of filters, typically provided by mixing in play.filters.HttpFiltersComponents or play.api.NoHttpFiltersComponents.

    In most cases you will want to mixin HttpFiltersComponents and append your own filters:

    class MyComponents(context: ApplicationLoader.Context)
      extends BuiltInComponentsFromContext(context)
      with play.filters.HttpFiltersComponents {
    
      lazy val loggingFilter = new LoggingFilter()
      override def httpFilters = {
        super.httpFilters :+ loggingFilter
      }
    }

    If you want to filter elements out of the list, you can do the following:

    class MyComponents(context: ApplicationLoader.Context)
      extends BuiltInComponentsFromContext(context)
      with play.filters.HttpFiltersComponents {
      override def httpFilters = {
        super.httpFilters.filterNot(_.getClass == classOf[CSRFFilter])
      }
    }
