What Is Spring Framework in Java?

Spring Framework offers a Java-based framework that provides lightweight power to develop applications which scale and remain easy to maintain. The framework executes Inversion of Control (IoC) and Dependency Injection (DI) techniques to handle dependencies hence minimizing code repetition and improving testing capabilities.

With its AOP functionality Spring enables programmers to manage common application concerns known as cross-cutting concerns including logging security transactions. Users can choose from a range of Spring ecosystem components which include Spring MVC for web applications and both Spring Boot for microservices and Spring Cloud for cloud integration while developing with Java.
