I’ve been doing some development work on an Online Store with Grails for sometime now, but have not yet investigated the use of AOP with Groovy.
John McClean has a lengthy but very clear article on InfoQ.com that walks you through how to create around, before and after advice on a Groovy class. This article is defintely worth a read, as it is something that I hadn’t picked up on that is possible with Groovy.
