(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.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.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.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.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 @RequestBodyBean 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 Injection8. Spring boot Bean Scopes9. How to Dynamically initialized Beans10. Spring boot @ConditionalOnProperty Annotation11. Spring boot @Profile annotation12. Spring boot AOP (Aspect Oriented Programming)13. Spring boot @Transactional Annotation14. Spring boot @Async Annotation15. Spring boot: Custom Interceptors16. Spring boot: Filters vs Interceptors17. Spring boot HATEOAS Restful API18. Spring boot ResponseEntity and Response Codes19. Spring boot - Exception Handling
