  • 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.

SimpleInjector

class SimpleInjector extends Injector

A simple map backed injector.

This injector is intended for use by compile time injected applications in the transitional period between when Play fully supports dependency injection across the whole code base, and when some parts of Play still access core components through Play's global state. Since Play's global state requires that some components are still dynamically looked up from an injector, when using a compile time DI approach, there is typically no way to dynamically look up components, so this provides a simple implementation of the Injector trait to allow components that Play requires to be dynamically looked up.

It is intended to just hold built in Play components, but may be used to add additional components by end users when required.

The injector is an immutable structure, new components can be added using the + convenience method, which returns a new injector with that component included.
