So far I’ve shown how to produce JSON from simple collections and how to convert domain objects to JSON, in this final post in my three-part look at rendering JSON from Grails controllers, we’ll take a look at customising the way objects are rendered by the JSON converter. Continue reading
I love having the ability to create property getter and setter methods in Groovy and it really simplifies all those bean accessors in Grails domain classes. At least, it does until you define one incorrectly and spend an embarrassingly long time trying to work out why data in your Grails controller isn’t being bound… Continue reading

Having implemented such behaviour I’ve found that a little more than the basic understanding is helpful for success in real applications, so over the next 3 posts I will attempt to convey the simplicity and power of this feature while also giving some practical tips.
