Microservice Architecture with Grails
summary
Grails 3 builds microservices by exposing domain classes as REST endpoints with @Resource + resources URL mapping, using RestBuilder for inter-service calls and GORM queries for data filtering. The demo runs three apps (web UI on 8080, bank on 8082, cars on 8084), the UI calls bank and car services over JSON, and versioning uses an Accept header switch. RestfulController hooks like queryForResource and getObjectToBind are overridable; GORM-for-REST is available and over 1,100 Grails 2 plugins require porting.
