The Grails Object Relational Mapping (GORM) API is an elegant domain specific language on top of Hibernate. To really understand how it works, you need to understand how Hibernate sees the world. This workshop will explore the behavior of GORM, from following object state transitions to managing the session to fetching lazy associations and more.
While the focus will be Grails and understanding how it works, code samples will also be provided using plain Hibernate with the Spring Framework to manage the session factory and transactions. All examples will be built with Gradle and tested with both JUnit and Spock.
