  • 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.

Module

abstract class Module extends AnyRef

A Play dependency injection module.

Dependency injection modules can be used by Play plugins to provide bindings for JSR-330 compliant ApplicationLoaders. Any plugin that wants to provide components that a Play application can use may implement one of these.

Providing custom modules can be done by appending their fully qualified class names to play.modules.enabled in application.conf, for example

play.modules.enabled += "com.example.FooModule"
play.modules.enabled += "com.example.BarModule"

It is strongly advised that in addition to providing a module for JSR-330 DI, that plugins also provide a Scala trait that constructs the modules manually. This allows for use of the module without needing a runtime dependency injection provider.

The bind methods are provided only as a DSL for specifying bindings. For example:

def bindings(env: Environment, conf: Configuration) = Seq(
  bind[Foo].to[FooImpl],
  bind[Bar].to(new Bar()),
  bind[Foo].qualifiedWith[SomeQualifier].to[OtherFoo]
)

Abstract Value Members

  1. abstract def bindings(environment: Environment, configuration: Configuration): Seq[Binding[_]]

    Get the bindings provided by this module.

    Get the bindings provided by this module.

    Implementations are strongly encouraged to do *nothing* in this method other than provide bindings. Startup should be handled in the constructors and/or providers bound in the returned bindings. Dependencies on other modules or components should be expressed through constructor arguments.

    The configuration and environment a provided for the purpose of producing dynamic bindings, for example, if what gets bound depends on some configuration, this may be read to control that.
