A powerful Groovy-based web application framework for the JVM built on top of Spring Boot. Convention-over-configuration, sensible defaults, opinionated APIs, and the Groovy language combine to make the Grails® framework easy to learn for Java developers. The Grails framework is built on top of Spring Boot and leverages Spring Boot's time-saving features, such as Spring-powered dependency injection. The Grails framework seamlessly and transparently integrates and interoperates with Java, the JVM, and existing Java EE containers. Apache Groovy is a language for the Java platform designed to enhance developers' productivity. It is an optionally-typed and dynamic language but with static-typing and static compilation capabilities. The Grails framework seamlessly integrates with GORM, a data access toolkit that provides a rich set of APIs for accessing relational and non-relational data. GORM also includes implementations for Hibernate (SQL), MongoDB, Cassandra, and Neo4j.
