Overview

At the heart of the Spring Framework are the modules that implement the core container, including a configuration model and a dependency injection mechanism. Support for different application architectures, including messaging, transactions and persistence is built in top of the core container.

Inversion of Control Container

Configuration Model

XML-based Configuration

Java-based Configuration (@Configuration). Annotation injection is performed before XML injection, thus the XML configuration overrides the annotations for properties wired through both approaches.

Configuration time. Define what that is.
