From the previous episode: Spring Beans are components that make up the core of the Spring Framework. They are the building blocks for creating applications in the Spring ecosystem. The framework uses the Inversion of Control (IoC) principle to manage the lifecycle and dependencies of these beans. Spring Beans can be defined using XML configuration files, Java configuration, or annotation-based configuration. The use of Spring Beans results in a loosely-coupled architecture, where changes to one component do not affect the rest of the application. This makes the application more flexible and easier to maintain. Additionally, Spring Beans can be easily tested in isolation, promoting maintainability and reducing the risk of introducing bugs.
