Configuring DAO packages in Guice

We need to configure the injections for the three new dao packages that we created. So we to need to add three lines in the file Module.scala. Please open the file in your IDE, and add the following content:

bind(classOf[IProductDao]).to(classOf[ProductDao]).asEagerSingleton()

bind(classOf[IImageDao]).to(classOf[ImageDao]).asEagerSingleton()

bind(classOf[IReviewDao]).to(classOf[ReviewDao]).asEagerSingleton

The whole file, Module.scala, should look like this:

/**

• * This class is a Guice module that tells Guice how to bind several
• * different types. This Guice module is created when the Play
• * application starts.
• * Play will automatically use any class called 'Module' that is in
• * the root package. You can create modules in other locations by
• * adding 'play.modules.enabled' settings to the 'application.conf'
• * configuration file.
• */

class Module extends AbstractModule { override def configure() = {

// Use the system clock as the default implementation of Clock bind(classOf[Clock]).toInstance(Clock.systemDefaultZone)

// Ask Guice to create an instance of ApplicationTimer when //the application starts.

bind(classOf[ApplicationTimer]).asEagerSingleton()

bind(classOf[IProductService]).

to(classOf[ProductService]).asEagerSingleton()

bind(classOf[IReviewService]).

to(classOf[ReviewService]).asEagerSingleton()

bind(classOf[IImageService]).

to(classOf[ImageService]).asEagerSingleton()

bind(classOf[IPriceSerice]).

to(classOf[PriceService]).asEagerSingleton()

bind(classOf[IRndService]).

to(classOf[RndService]).asEagerSingleton()

bind(classOf[IProductDao]).

to(classOf[ProductDao]).asEagerSingleton()

bind(classOf[IImageDao]).

to(classOf[ImageDao]).asEagerSingleton()

bind(classOf[IReviewDao]).

to(classOf[ReviewDao]).asEagerSingleton()

}

}
