Grails is an open source framework for rapid web application development. It is based on the Groovy programming language and built on Spring, Hibernate and other standard Java frameworks, thus bringing you a one-stop framework that can achieve ultra-high productivity. .
Ruby on Rails pioneered the creative combination of a powerful programming language and an opinionated framework that promoted the replacement of complex configurations with sensible defaults. However, there are many organizations that are not ready to move away from Java's security umbrella or abandon their current investment in Java. The emergence of Grails makes it possible to achieve the same productivity in a Java-centric environment.
