Spring Framework

The Spring Framework is an application framework and inversion of control

The framework has become popular in the Java community as an addition to the Enterprise JavaBeans

The Spring Framework is free and open source software.

The inversion of control (IoC) container is the core container in the Spring Framework.

It provides a consistent means of configuring and managing Java objects CONSUMER SENTIMENT

The container is responsible for managing object lifecycles of specific objects

Objects created by the container are called managed objects or beans

The @Configuration is a Spring-specific annotation that marks a class as the configuration class that provides the beans to the Spring ApplicationContext

There are several types of Inversion of Control.

Dependency injection and dependency lookup are examples of Inversion of Control.

Dependency injection is a pattern where the container passes objects by name to other objects, via either constructors, properties, or factory methods

Dependency lookup is a pattern where a caller asks the container object for an object with a specific name or of a specific type.

The Spring framework has a feature known as autowiring, which use the spring container to automatically satisfy the dependencies specified in the JavaBean properties to objects of the appropriate type in the current factory

There are several annotations that can be used for autowiring POJOs, including the Spring-specific annotation

The Spring Framework has its own Aspect-oriented programming (AOP) framework that modularizes cross-cutting concerns in aspects

Spring's transaction management framework brings an abstraction mechanism to the Java platform

The Spring Framework features its own model–view–controller (MVC) web application framework
