In the last article, we have created “Play for Java” application using Activator. In this article, we will try to explore the project folder structure. In the last article, we have created project name as “Learning_Play_App”. The folder structure follows as shown below.

| +---app
| | +---controllers
| | +---views
| +---conf
| +---logs
| +---project
| | +---project
| | +---target
| |
| +---public
| | +---images
| | +---javascripts
| | +---stylesheets
| +---target
| | 
| +---test
  • The “app” folder contains controllers and views. For any enterprise application, if you want to add other source code folder like model, you can very well create “model” folder under “app” and keep all your domain models under it.
  • The “conf” folder contains all the configuration files.
    • application.conf –> contains all the application related configurations like database connectivity details, web application context path details etc…
    • logback.xml –> contains the application logging related configuration details.
    • routes –> you need to configure all the REST services end points over here.
  • The “logs” folder contains the application log file.
  • The “projects” folder contains build.properties and plugins.sbt where you can mention plugin related details.
  • The “public” folder contains all the static assets like Javascript, images, and CSS.
  • The “test” contains all the unit test cases.
  • The “build.sbt” under the root application folder contains all the third party related dependencies.

The below picture represents the entire folder structure.
