In Grails they stress convention over configuration. Grails basic structures follow the MVC pattern. The grails-app/domain directory holds the Models, the grails-app/views directory holds the Views and the grails-app/controllers directory holds the Controllers. There are are:
%PROJECT HOME%
- grails-app
- conf
- BootStrap.groovy <- Initializes the database with given data.
- BuildConfig.groovy <- Holds configurations for the build (dependencies, plugins, repositories, error logging level).
- Config.groovy <- Holds various configurations for the project.
- DataSource.groovy <- Holds database settings for each type of environment.
- SpringSecurityConfig.groovy <- Holds additional configuration settings for the Spring Security plugins. Has to be included at the
beginning of Config.groovy. - UrlMappings.groovy <- Allows the changing of the Url scheme.
- controllers <- Holds the controller classes.
- domain <- Holds the model classes, grails will by default create a corresponding table for each file in this directory.
- services <- Directory to hold any services the application will host.
- views <- Holds the view gsps.
- conf
- lib
- scripts <- Holds the various grails command scripts as well as any user-defined scripts.
- src
- groovy <- Generic groovy source files that don't have a conventional location.
- java <- Java source files, will be compiled and included in WAR file.
- test <- Holds the test files that will be run by the "grails test-app" script.
