Prerequisites

• Basic knowledge of Java programming (understanding of classes, objects, methods, and basic syntax).
• Familiarity with IDEs like IntelliJ IDEA or Eclipse (optional but recommended).
• A basic understanding of web concepts (e.g., HTTP, APIs) is helpful but not mandatory.

Course Outline

1. Introduction to Spring Framework and Spring Boot

• The evolution of Java application development.
• What is the Spring Framework?
  • Core concepts: Dependency Injection (DI) and Aspect-Oriented Programming (AOP).
• Introduction to Spring Boot:
  • Features and benefits.
  • Comparing Spring Boot with traditional Spring applications.
• Setting up the environment:
  • Installing JDK, Maven, and IntelliJ IDEA/Eclipse.
  • Creating your first Spring Boot project using Spring Initializr.

2. Spring Boot Fundamentals

• Understanding the structure of a Spring Boot application.
• Dependency management using Maven.
• Configuration basics:
  • application.properties vs application.yml.
  • Profiles and environment-specific configurations.
• Running and debugging Spring Boot applications.

3. Building RESTful Web Services

• Introduction to REST architecture:
  • Key principles and HTTP methods.
• Creating RESTful APIs using Spring Boot.
  • @RestController and @RequestMapping annotations.
  • Handling HTTP GET, POST, PUT, DELETE requests.
• Data validation with @Valid and Bean Validation.
• Exception handling in Spring Boot:
  • @ControllerAdvice and @ExceptionHandler.
• Practical exercise: Build a simple "To-Do List" REST API.

4. Working with Data in Spring Boot

• Introduction to Spring Data JPA:
  • Benefits of JPA and Hibernate.
  • Setting up a database connection (H2, MySQL).
• Defining entities and repositories:
  • @Entity, @Id, @GeneratedValue annotations.
  • Repository interfaces and query methods.
• CRUD operations with Spring Data JPA.
• Pagination and sorting.
• Practical exercise: Extend the "To-Do List" app with database persistence.

5. Working with Spring Boot and Apache Kafka

• Introduction to Apache Kafka
  • What is Apache Kafka?
    • Overview of Kafka as a distributed event-streaming platform.
    • Key use cases: real-time analytics, event-driven architecture, log aggregation, and more.
  • Core Kafka concepts:
    • Topics, producers, and consumers.
    • Partitions and offsets.
    • Brokers and Kafka clusters.
    • Consumer groups and message delivery semantics (at-least-once, at-most-once, exactly-once).
  • Benefits of using Kafka in modern applications:
    • Scalability, durability, and high-throughput.
• Integrating Spring Boot with Kafka
• Setting up Kafka in a development environment:
  • Installing and running Kafka locally.
  • Exploring tools like Confluent Platform or Docker for Kafka setup.
• Adding Kafka dependencies to a Spring Boot project using Maven/Gradle.
• Configuring Kafka in Spring Boot:
  • Defining properties in application.yml or application.properties.
  • Understanding producer and consumer configuration.

7. Deploying Spring Boot Applications

• Overview of deployment options:
  • Running Spring Boot as a standalone JAR.
  • Deploying to application servers (e.g., Tomcat).
  • Cloud deployments with AWS Elastic Beanstalk or Azure App Services.
• Configuring Spring Boot for production:
  • Logging with Spring Boot.
  • Monitoring and metrics using Actuator.
• Practical exercise: Deploy app locally and explore deployment options for the cloud.
