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.

    environment

    The environment

    configuration

    The configuration

    returns

    A sequence of bindings

Concrete Value Members

  1. final def bind[T](implicit arg0: ClassTag[T]): BindingKey[T]

    Create a binding key for the given class.

Deprecated Value Members

  1. final def bind[T](clazz: Class[T]): BindingKey[T]

    Create a binding key for the given class.

    Create a binding key for the given class.

    (Since version 2.7.0) Use play.inject.Module.bindClass instead if the Module is coded in Java. Scala modules can use play.api.inject.bind[T: ClassTag]

  2. final def seq(bindings: Binding[_]*): Seq[Binding[_]]

    Create a seq.

    Create a seq.
