  Spring Autowiring using @Autowired Annotation Introduction Wiring : Process of defining object dependencies so that Spring can auto-inject the dependent objects into the target bean. Types of Wiring : Manual Wiring : Explicitly specifying dependencies in configuration files. Autowiring : Letting Spring handle dependency injection automatically. Autowiring in Spring Autowiring in Spring allows automatic dependency injection using the @Autowired annotation. Spring container automatically resolves the dependencies and injects them into the appropriate beans. Example Use-Case for Field Injection Below is an example where a Student class has a dependency on a Department class. We use the @Autowired annotation to inject the Department dependency automatically. Student.java import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; @Component public class Student { @Autowired private...

  Understanding the Spring Core Module: The Foundation of Spring Framework Introduction Spring Framework is one of the most widely used frameworks in Java development, and at the heart of it lies the Spring Core Module . This module provides the foundation for other Spring components and enables efficient dependency management and inversion of control (IoC). In this blog post, we’ll explore what the Spring Core Module is, how it works, and why it’s essential for building enterprise applications. What is the Spring Core Module? The Spring Core Module is the fundamental building block of the Spring Framework. It provides essential components like: ApplicationContext and BeanFactory , which manage the lifecycle of beans. IoC (Inversion of Control) containers , which handle object creation and dependency management. Dependency Injection (DI) mechanisms , which allow objects to be loosely coupled, improving maintainability and scalability. This module is used in both standal...
