Grails JSON Parser

Here is a quick example on parsing JSON in grails using groovy (surprisingly, google isn't returning any good hits). Also, if you needed this ability in just straight groovy, I am sure you could include the specific grails jar in your classpath.

import grails.converters.*

def jsonArray = JSON.parse("""['foo','bar', { a: 'JSONObject' }]""")
println "Class of jsonArray: ${jsonArray.class.name}"
jsonArray.each { println "Value: ${it}" }

FYI, it appears from the mailing list this was added around 1.0 RC1.

Building JSON is super easy too in grails/groovy using the render as. And don't forget to import grails.converters.

render Book.list(params) as JSON

Update: Read my recent article on testing REST Services that return JSON using groovy and httpbuilder.
