Building an Enterprise CRM with Grails and Spring Integration
summary
An enterprise CRM at Dealer.com proves that a Grails front end and a Spring-driven backend can be built for heavy write workloads and horizontal scaling: two stateless Grails apps (UI + services) talk JSON REST, domain objects live in a shared plugin, search uses ElasticSearch, primary storage is MongoDB, and async integration is handled with RabbitMQ and Spring AMQP. Key engineered pieces are a form scope with token and an onsubmit DSL for complex collection edits, plus a message-driven persistence pipeline using Grails + Spring Integration with retries and dead‑lettering; the system is deployed and serves a large dealer base.
