Spring Boot Course Topics
01Spring Boot Introduction
Understand what Spring Boot is, why it is used, and how it simplifies enterprise Java development. Learn the framework’s core ideas, auto-configuration, starters, embedded servers, and production-ready application structure.
→ 02Spring Boot Setup
Prepare your development environment with Java, Maven, IntelliJ IDEA, and Spring Initializr. Create a working project, understand dependencies, run the application, and verify your first Spring Boot endpoint.
→ 03Project Structure
Organize a Spring Boot project using packages, configuration files, resources, controllers, services, repositories, DTOs, and tests. Follow conventions that keep growing applications clear and maintainable.
→ 04Spring AOP
Separate cross-cutting concerns such as logging, auditing, transactions, and security from business logic. Understand aspects, pointcuts, advice, proxies, and practical AOP patterns in Spring Boot.
→ 05Spring Data JPA
Connect Spring Boot applications to relational databases with entities, repositories, relationships, queries, pagination, transactions, and validation. Build a clean persistence layer with Hibernate and JPA.
→ 06REST API Development
Build production-style REST endpoints with controllers, request mappings, DTOs, validation, response entities, status codes, and JSON. Learn how to structure APIs that clients can use reliably.
→ 07REST API Design
Design consistent APIs with resource naming, HTTP methods, error responses, pagination, versioning, idempotency, and security boundaries. Apply practical conventions for maintainable backend services.
→ 08Request Validation
Protect API boundaries with Bean Validation, DTO constraints, nested validation, custom rules, method validation, and useful error responses. Keep invalid input out of application business logic.
→ 09Global Exception Handling
Create consistent error responses with RestControllerAdvice, exception handlers, status codes, validation errors, and safe messages. Make APIs easier to debug for developers and clients.
→ 10Spring Security
Secure Spring Boot applications with authentication, authorization, password handling, roles, permissions, filters, JWT concepts, and protected endpoints. Build a practical security foundation for APIs.
→ 11Spring Boot Testing
Test controllers, services, repositories, and application wiring with focused unit and integration tests. Learn useful Spring test annotations, mocks, test data, and reliable test organization.
→ 12Comprehensive Testing
Go deeper into test strategy with slices, MockMvc, integration environments, database tests, test profiles, and maintainable test suites. Balance speed, coverage, confidence, and realistic behavior.
→ 13Actuator and Monitoring
Monitor Spring Boot applications with health checks, liveness, readiness, metrics, endpoint security, Prometheus, Grafana, and custom indicators. Prepare services for production operations and observability.
→ 14Deployment
Prepare Spring Boot applications for deployment with packaging, environment configuration, profiles, containers, cloud platforms, logs, health checks, and reliable production startup strategies.
→ 15Profiles and Configuration
Separate development, testing, staging, and production settings without changing application code. Use profile files, activation methods, externalized configuration, and safe handling of environment-specific values.
→ 16HikariCP Connection Pool
Understand how database connection pools improve application performance and reliability. Configure HikariCP settings, monitor connections, avoid common mistakes, and tune database access responsibly.
→ 17File Uploads
Build safe multipart file upload endpoints with validation, size limits, storage strategies, filenames, content types, error handling, and download responses for real Spring Boot applications.
→ 18Scheduling
Run recurring background tasks with Spring scheduling. Configure cron expressions, fixed delays, thread pools, error handling, time zones, and operational safeguards for reliable scheduled jobs.
→ 19Redis Caching
Improve response times with caching and Redis. Learn cache keys, expiration, serialization, invalidation, cache abstraction, failure considerations, and patterns for data that changes frequently.
→ 20Spring Boot 2 to 3 Migration
Plan a safe upgrade from Spring Boot 2 to 3 with Java versions, Jakarta namespace changes, dependency updates, security changes, testing, observability, and deployment verification.
