1. Standalone GORM Michael Collado

2. What is Hibernate? Object –Relational mapping tool Object-Oriented querying Database agnostic query language XML configuration or annotations

3. Typical Hibernate Java bean and configuration Event.java Event.hbm.xml

5. What is GORM? Groovy layer over Hibernate Convention over configuration mapping Dynamic finder/persistence methods DSL based querying

6. Equivalent GORM entity definition Event.groovv

9. Maven groovy plugin

11. Set up GORM in Spring GORM XML namespace

12. Add sessionFactory bean and dependencies

13. Create TestBean entity TestBean.groovy

14. Create TestBean entity

15. Use Java interface to bridge Java - Groovy EntityManager.java TestBeanManager.java

16. Using GORM dynamic methods TestBeanManagerImpl.groovy

17. This works… but… My database schema looks like this:

18. Groovy Metaprogramming Use JDK Proxy to implement interfaces Use Groovy MetaMethods to call GORM methods dynamically invokeMethod methodMissing

19. DynamicManagerImpl.groovy
