Spring Boot Foundations, Architecture, and Why It Matters
Understand what Spring Boot is, how it relates to the wider Spring ecosystem, why it became popular, and what problems it solves for modern Java application development.
Chapter 2Project Setup, Spring Initializr, Starters, Maven, and Gradle
Learn how to create Spring Boot applications, choose starters, understand dependency management, and structure a project for clean development.
Chapter 3Configuration, application.properties, YAML, Profiles, and Externalization
Understand how Spring Boot manages configuration across environments using properties, YAML files, environment variables, and profiles.
Chapter 4Dependency Injection, Beans, Scopes, and Lifecycle
Build a strong understanding of inversion of control, bean creation, scopes, lifecycle callbacks, and clean application structure.
Chapter 5REST APIs, Controllers, Routing, Request Handling, and Responses
Learn how to build HTTP APIs with Spring Boot using controllers, request mapping, path variables, query parameters, request bodies, and response entities.
Chapter 6Service Layer, DTOs, Mapping, and Clean Architecture Patterns
Move beyond basic controllers and learn how to structure Spring Boot applications with clean service boundaries, DTOs, and maintainable architecture.
Chapter 7Spring Data JPA, Hibernate, Entities, Repositories, and Transactions
Learn how Spring Boot works with relational databases through JPA, Hibernate, repository abstraction, entity modeling, and transaction management.
Chapter 8Validation, Exception Handling, Error Responses, and API Design
Improve API quality with request validation, consistent error handling, meaningful HTTP responses, and clean contract design.
Chapter 9Spring Security, Authentication, Authorization, Sessions, and JWT
Learn how to secure Spring Boot applications using Spring Security, login flows, role-based access control, sessions, and token-based authentication.
Chapter 10Testing Spring Boot: Unit Tests, Integration Tests, MockMvc, and Test Slices
Build confidence in your application with service tests, controller tests, repository tests, integration tests, and maintainable testing strategy.
Chapter 11Logging, Actuator, Metrics, Health Checks, and Observability
Learn how to make Spring Boot applications visible and operable in production through structured logging, health endpoints, metrics, and observability tools.
Chapter 12Caching, Async Processing, Scheduling, Messaging, and Background Work
Understand how Spring Boot handles non-blocking work, scheduled jobs, cache acceleration, and integration with message-driven architecture.
Chapter 13Docker, Kubernetes, Deployment, CI/CD, and DevOps-Friendly Spring Boot
Learn how Spring Boot applications move from local development into containers, deployment pipelines, cloud platforms, and production environments.
Chapter 14Microservices, Spring Cloud, Resilience, and Distributed System Patterns
Connect Spring Boot to microservice architecture, service discovery, resilience patterns, configuration, and distributed communication.
Chapter 15Advanced Spring Boot: Auto-Configuration Internals, Performance, and Native Images
Go deeper into how Spring Boot works behind the scenes and explore advanced topics such as auto-configuration customization, startup tuning, and native deployment.
Chapter 16Projects, Interview Preparation, and Spring Boot Mastery Roadmap
Finish with practical project ideas, interview preparation guidance, and a structured roadmap to move from Spring Boot beginner to confident production developer.
