Spring Boot is a convention-over-configuration extension for the Spring Java platform intended to help minimize configuration concerns while creating Spring-based applications. [ 4 ] [ 5 ] The application can still be adjusted for specific needs, but the initial Spring Boot project provides a preconfigured "opinionated view" of the best ...
Address the development, deployment, and runtime aspects of an enterprise application’s life cycle. Define the contracts that enable tools from multiple vendors to develop and deploy components that can interoperate at runtime. Be compatible with existing server platforms. Vendors will be able to extend their existing products to support EJBs.
