Spring Roo is a development tool that aims to improve Java developer productivity without compromising flexibility or performance. It uses code generation techniques to rapidly generate Spring-based applications. Spring Roo supports features like entity management, persistence, testing, security, and internationalization. It can also generate code to support deployment to the cloud. While powerful, Spring Roo is a code generation tool and its annotations and code can be removed from an application as it is developed further.
