Apr 22, 2025

Spring Boot Course Overview

Introduction

  • Welcome to the Spring Boot course.
  • Focus on building RESTful APIs and web applications with Spring Boot.
  • Overview includes creating API, connecting to a real database using Docker, with Postgres and JPA.

Platform Introduction

  • Introduction to Migos Code 2.0 platform with new features like dashboard, courses, tools, and content.
  • Offers exercises and certificates.
  • Encouragement to enroll for full benefits.

Tools and Setup

  • IntelliJ: Recommended IDE for Java and JVM-based projects.
    • Offers a 3-month free IntelliJ subscription.
  • Toolbox: Tool for managing JetBrains IDE licenses.

Project Setup

  • Steps to create a new Spring Boot project using IntelliJ:
    • Choose project location and settings (language, build tool, etc.).
    • Select dependencies (e.g., Spring Boot, Maven).
    • Setting up Git repository for code versioning.
  • Ensuring JDK installation and configuration.

Creating a Spring Boot API

  • Steps to create a simple REST API:
    • Define main application class with @SpringBootApplication.
    • Create REST endpoint using @RestController and @GetMapping.
  • Running the application and testing with REST clients.

Building a CRUD API

  • Outline for creating CRUD operations: GET, POST, PUT, DELETE.
  • Introduction to Docker and Postgres for database integration.

Docker and Postgres Setup

  • Introduction to Docker:
    • Benefits: Portability, resource efficiency, and rapid deployment.
    • Key concepts: Containers, images, Dockerfile, Docker Compose, registries.
  • Steps to install Docker and verify installation.
  • Using Docker Hub to find Postgres image.
  • Creating a Docker Compose file to set up Postgres.
  • Running and managing Docker containers.

Connecting Spring Boot to Database

  • Adding necessary dependencies for SQL and JPA.
  • Configuring application properties for database connection (URL, username, password).
  • Creating and managing database using Postgres and Docker.

Spring Data JPA Integration

  • Entity Creation:
    • Annotating Java classes with @Entity and @Id to map to database tables.
  • Repositories:
    • Using JpaRepository to define repository interfaces.
    • Handling CRUD operations with pre-defined methods.

Implementing API Methods

  • Service Layer: Encapsulates business logic and interacts with repository layer.
  • Controller Layer:
    • Defining endpoints and handling HTTP requests.
    • Using annotations like @PostMapping, @RequestBody, and @PathVariable.

Practical Examples and Testing

  • Testing APIs with HTTP requests using IntelliJ’s built-in REST client.
  • Demonstrating CRUD operations (Create, Read, Update, Delete) with examples.

Conclusion and Further Learning

  • Encouragement to continue with exercises and further learning through platform enrollment.
  • Mention of comprehensive Java and Spring Boot developer roadmap offered by the platform.
