We have long-time Grails user David Dawson giving us an alternative application architecture to stateless services, one based on command objects! Title and abstract follow.
All hail the command object: are stateless services the only way?
Grails has inherited the stateless service, from spring, as one of the central ways to write a web application. It even goes as far as to make it one of the main conventions. This works, for the most part, but is it the only way?
David discusses, with production examples, another way of using all the niceties of the grails architecture to tease out the service spaghetti and bring state and logic back together.
