Backend Engineering #5 — Spring Boot Annotations & Application Context

In this session, we go hands-on with Spring Boot annotations and understand what actually happens when a Spring Boot application starts. We cover how Spring Boot runs, how the ApplicationContext is created, how Spring discovers and manages Beans, and how annotations connect different parts of a backend application. Topics covered: Spring Boot application startup @SpringBootApplication Spring IoC Container & ApplicationContext Spring Beans & Component Scanning Dependency Injection Common Spring Boot annotations Controller, Service & Repository annotations HTTP mapping annotations @Configuration & @Bean Validation & exception handling annotations Practical usage through a Spring Boot project The goal is to understand what Spring is actually doing behind the scenes, instead of just memorising annotations.
