SPRING FRAMEWORK what is spring framework? The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.

SPRING FRAMEWORK prerequisite - Eclipse - Maven or Gradle

GRADLE WHAT IS GRADLE? Gradle is an open source build automation system. Gradle can automate the building, testing, publishing, deployment and more of software packages or other types of projects such as generated static websites, generated documentation or indeed anything else. Gradle combines the power and flexibility of Ant with the dependency management and conventions of Maven into a more effective way to build. Powered by Build Programming Language, Gradle is concise yet expressive.AntMaven
