SpringRoo is an open source tool that enables rapid Java web application development. It uses code generation and conventions to quickly generate common structures like entities, repositories, services, and web layers. Developers can focus on business logic rather than boilerplate coding. SpringRoo allows creating full-featured Java applications quickly without compromising on technology choices or best practices. It utilizes standard Java, Spring, AspectJ, and Maven to build applications for easy long-term maintenance and development.
