  • 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.

trait Application extends AnyRef

A Play application.

Application creation is handled by the framework engine.

If you need to create an ad-hoc application, for example in case of unit testing, you can easily achieve this using:

val application = new DefaultApplication(new File("."), this.getClass.getClassloader, None, Play.Mode.Dev)

This will create an application using the current classloader.

Deprecated Value Members

  1. def getExistingFile(relativePath: String): Option[File]

    Retrieves a file relative to the application root path.

    Retrieves a file relative to the application root path. This method returns an Option[File], using None if the file was not found.

    Note that it is up to you to manage the files in the application root path in production. By default, there will be nothing available in the application root path.

    For example, to retrieve some deployment specific data file:

    val myDataFile = application.getExistingFile("data/data.xml")
    relativePath

    the relative path of the file to fetch

    returns

    an existing file

    Scans the application classloader to retrieve a resource.

    The conf directory is included on the classpath, so this may be used to look up resources, relative to the conf directory.

    For example, to retrieve the conf/logback.xml configuration file:

    val maybeConf = application.resource("logback.xml")
    name

    the absolute name of the resource (from the classpath root)

    returns

    the resource URL, if found
