This class is meant for students who want to develop REST API applications but don't know how to do it. During the course you will learn the basics of REST APIs, how to use SpringBoot for developing the REST APIs. Hour 1: Introduction to Spring Boot and REST APIs 1.1 Overview of Spring Boot and Microservices • Introduction to Spring Boot framework • Understanding the concept of microservices architecture 1.2 Setting Up Development Environment • Installing Java Development Kit (JDK) • Setting up Spring Boot project using Spring Initializer • Introduction to REST APIs 1.3 Creating Your First Spring Boot REST Controller • Defining a REST endpoint • Handling HTTP requests (GET, POST, PUT, DELETE) • Returning JSON responses Hour 2: Data Persistence with Spring Boot 2.1 Introduction to Data Persistence • Overview of ORM (Object-Relational Mapping) and JPA (Java Persistence API) • Introduction to Spring Data JPA 2.2 Configuring Data Source and JPA Entities • Setting up database configuration in Spring Boot • Creating JPA entities to represent database tables • Mapping entities to database tables using annotations 2.3 CRUD Operations with Spring Data JPA • Implementing CRUD (Create, Read, Update, Delete) operations using Spring Data JPA repositories • Testing CRUD operations with Postman or similar tool Hour 3: Advanced REST API Concepts 3.1 Request and Response Payload • Handling request parameters and payloads • Customizing response entities 3.2 Error Handling • Handling exceptions in Spring Boot REST APIs • Implementing custom error responses 3.3 Validation • Validating request parameters and payloads using javax.validation annotations • Customizing validation messages Hour 4: Introduction to Microservices Architecture 4.1 Microservices Architecture Overview • Understanding the benefits and challenges of microservices • Key principles of microservices architecture 4.2 Service Registration and Discovery • Introduction to service registration and discovery 4.3 Building Microservices with Spring Boot • Creating multiple Spring Boot applications representing microservices • Communicating between microservices using REST APIs Hour 5: Implementing API Gateway 5.1 Introduction to API Gateway • Understanding the role of API Gateway in microservices architecture • Overview of Spring Cloud Gateway 5.2 Configuring API Gateway with Spring Cloud Gateway • Setting up API Gateway in a Spring Boot application • Implementing routing and filtering Hour 6: Service-to-Service Communication 6.1 Synchronous Communication • Implementing synchronous communication between microservices using REST Template 6.2 Asynchronous Communication • Introduction to asynchronous communication using messaging queues (e.g., RabbitMQ, Kafka) • Integrating messaging queues with Spring Boot applications Hour 7: Authentication and Authorization 7.1 Introduction to Security in Microservices • Understanding the importance of security in microservices architecture • Overview of authentication and authorization mechanisms 7.2 Implementing Authentication with Spring Security • Securing microservices with Spring Security • Implementing authentication using JSON Web Tokens (JWT) Hour 8: Containerization and Deployment Strategies 8.1 Introduction to Docker • Understanding containerization and Docker • Installing Docker and Docker Compose 8.2 Deployment Strategies • Overview of deployment strategies (e.g., Blue-Green deployment, Canary deployment) • Choosing the right deployment strategy for microservices 8.3 Scaling Microservices • Horizontal scaling with Kubernetes • Configuring Kubernetes deployment for Spring Boot applications 8.4 Containerizing Spring Boot Applications • Creating Docker images for Spring Boot applications • Running and managing containers with Docker Compose Hour 9: Standards and Best Practices 9.1 API first development and Open API • Overview of Open API Standards • API first development strategy • 12 factors of cloud native applications Hour 10: Monitoring and Logging 10.1 Monitoring Spring Boot Applications • Actuator Health checks 10.2 Logging • Configuring logging in Spring Boot applications
