Service method or domain static method in Grails?

Question

This is a design question:

• when do I need to create/use a static method (in a domain class for instance)
• when do I need to create/use a service instead?

What is the difference between them?

Answer 1

If the method is to do only with the behaviour/details of the domain class then I'd make it a method on the domain (not necessarlily a static one). If it is more related to business logic then I'd put it in a service.
