Restful Grails 3
summary
Grails 3 claims to cut boilerplate and demo shows it: @Resource auto‑exposes CRUD endpoints and URL mappings are generated so a domain class plus annotation yields full REST CRUD with curl-tested JSON/XML. Compile‑time metaprogramming creates no‑arg controller entrypoints, data binding and validation run before user code, and bindData(request) uses body JSON/XML or params automatically. Content negotiation via respond/withFormat and pluggable renderers let apps customize JSON/XML output; allowedMethods enforces HTTP verbs for safety.
