Topics covered till now for Spring boot:

In this course you will find below topics:

1. Introduction to Spring Boot: First i have covered the fundamentals of Spring Boot and its differentiation from Spring MVC. (Also covered by Servlets, which was way popular before Spring framework) This provides a foundational understanding of the framework’s significance in Java web development.

2. Project Setup in Spring Boot: The next step involves the setup of a Spring Boot project, essential for initiating our development endeavours. This phase ensures our environment is configured optimally for future application development.

3. Understanding Layered Architecture: Layered architecture is pivotal for the organisation and scalability of our applications. This concept enables us to structure our code in a manner that promotes modularity and maintainability.

4. Maven and Its Lifecycle: Maven serves as a powerful tool for project management and dependency resolution. Understanding its lifecycle is crucial for efficient project development and management of dependencies. We can create Spring boot project using Maven or Gradle, so understanding of this, i think is must.

5. Controller Layer Annotations: Get in-depth understanding of annotations such as @RestController and @RequestMapping facilitates the development of RESTful APIs. These annotations provide directives to Spring Boot, dictating the behavior of our controllers. Covered many other annotation like @RestController @Controller @Responebody @RequetMapping @RequestParam @PathVariable @InitBinder @RequestBody

6. Bean Lifecycle in Spring Boot: In this you will get to know about BEAN and its lifecycle, I have also explained about IOC (Inversion of Control) which manages those Bean.
   You will get to know about different ways of creating Bean (@Component and @Bean annotation), Different types when bean get created (Eagerly and Lazily).

7. Spring boot : Dependency Injection
8. Spring boot Bean Scopes
9. How to Dynamically initialized Beans

10. Spring boot @ConditionalOnProperty Annotation

11. Spring boot @Profile annotation

12. Spring boot AOP (Aspect Oriented Programming)

13. Spring boot @Transactional Annotation

14. Spring boot @Async Annotation

15. Spring boot: Custom Interceptors

16. Spring boot: Filters vs Interceptors

17. Spring boot HATEOAS Restful API

18. Spring boot ResponseEntity and Response Codes

19. Spring boot – Exception Handling
