Render map as json in Grails

问题

I'm using Grails for my application, and I have a problem with JSON converters.

In my controller, I have:

def myObject = [:]
myObject.key = 'value'
render ???

what is optimal way to render myObject as JSON from the controller?

回答1:

It's easy :

render (myObject as JSON)

or

render ([key: "value"] as JSON)

回答2:

Other way is :

        render (contentType: 'text/json'){
        array {
            for(f in Person.list()){
                person id: f.id, name: f.name
            }
        }
    }

This sample render a list of Persons
