Explore Spring Boot, a Java-based framework for building web apps, microservices, and RESTful APIs, and learn its MVC architecture from client to repository.
Create a spring boot 4 project via start.spring.io with maven and jar packaging. Add spring web, lombok, validation, h2, and jpa, then unzip and open in IntelliJ IDEA Community Edition.
Run the Spring Boot app, verify it starts on Tomcat port 8080, open localhost:8080, and use H2 in-memory database while commenting out MySQL and refreshing dependencies via pom.xml.
Learn to set up a Spring Boot 4 project, manage dependencies with Maven, and understand packaging into a jar, including JPA persistence, validation, Spring Web, and H2 database.
structure a spring boot app into controller, model, repository, and service packages, and model a product entity with id, name, description, price, and quantity using jpa and lombok.
Define a repository interface annotated with @Repository, extend JpaRepository for the product model with a long primary key, and use prebuilt CRUD methods to manage database operations.
Explore building a Spring service layer with IProductService and ProductServiceImplementation, performing CRUD via repository, including not-found handling and transactional updates.
Define a rest controller using spring boot annotations, map CRUD endpoints for products under /api/products, and return response entities while testing with an in-memory h2 database.
Discover end-to-end testing of a Spring Boot RESTful API with Postman, creating, retrieving, updating, and deleting products, and learn how an in-memory H2 database affects data persistence.
Learn to connect a Spring Boot app to a MySQL database by configuring jdbc url, driver class, and JPA properties, then persist data with an auto-created product table.
