The Spring website (https://projects.spring.io/spring-framework/) defines Spring Framework as follows: The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications.
Spring Framework is used to wire enterprise Java applications. The main aim of Spring Framework is to take care of all the technical plumbing that is needed in order to connect the different parts of an application. This allows programmers to focus on the crux of their jobs--writing business logic.
