Spring Beans & Bean Lifecycle | Spring Framework Tutorial | Episode - 03
What if I told you Spring creates your objects automatically even before your code runs? 🤯
In this video, we will understand Spring Beans and the Spring Bean Lifecycle in the simplest way using a plain Maven project (not Spring Boot).
You will learn:
✔ What is a Spring Bean?
✔ How Spring creates and manages beans automatically
✔ Bean lifecycle stages: Instantiation → Dependency Injection → Initialization → Destruction
✔ @Component, @Autowired, @Configuration, @ComponentScan annotations
✔ How @PostConstruct & @PreDestroy work
✔ Creating Spring IoC Container manually using AnnotationConfigApplicationContext
We will dive into code and console logs to clearly see every step of the lifecycle.
By the end, you will fully understand how Spring handles your objects behind the scenes! 💡
