Master REST API development through a complete event management system. This hands-on course teaches you to build scalable, maintainable APIs using Spring Boot—the skills companies actually hire for.

Why This Course Works

Tired of Spring Boot courses that teach “hello world” CRUD and call it production-ready? This course is different. You’ll build a real event management API with validation, search, pagination, business rules, and error handling—everything missing from basic tutorials but demanded in actual jobs.

No hand-holding through trivial examples. You’ll debug validation failures, fix query problems, and enforce business logic. By the end, you have a working API you can deploy, show in interviews, or expand into portfolio projects.

What You’ll Build

Create a complete REST API that handles the full event lifecycle—from draft creation through publication to completion. Your system will:

• Manage event states with enforced transitions between draft, published, cancelled, full, and completed statuses
• Search and filter intelligently by status, date ranges, and keywords—all paginated for real-world scale
• Validate rigorously at every layer with duplicate detection, business rules, and meaningful error messages
• Handle errors properly with global exception handling, appropriate HTTP codes, and actionable responses
• Follow clean architecture using controller-service-repository patterns, DTOs, and automated MapStruct transformations

This isn’t a toy app. It’s the kind of system companies build for conference management, ticketing platforms, and scheduling services.

Real Skills, Not Filler Content

• REST Architecture Fundamentals – Understand stateless communication, HTTP method semantics, and resource-oriented design. Learn why these principles matter beyond passing interviews.
• Spring Boot Project Structure – Configure projects correctly from the start. Set up environment profiles, integrate H2 for development, and build maintainable application structures.
• JPA Entity Modeling – Design entities that capture business concepts. Implement domain logic on models. Create repositories that query without writing SQL.
• Complete CRUD Operations – Build GET, POST, PUT, and DELETE endpoints with proper HTTP semantics. Handle path parameters and query strings. Return correct status codes.
• Multi-Layer Validation – Check required fields, enforce length limits, prevent duplicates, and validate business rules. Return errors users can actually fix.
• DTOs and Object Mapping – Separate API contracts from domain models. Use MapStruct to eliminate boilerplate transformation code.
• Advanced Query Features – Implement keyword search, date range filtering, and pagination. Create administrative operations with proper business rule enforcement.

What You’ll Learn

• Design REST APIs following industry standards that work at scale
• Implement complete CRUD with proper HTTP method usage and status codes
• Structure Spring Boot applications using proven MVC architecture
• Validate data at field, business, and database levels
• Handle errors with messages that tell users exactly what’s wrong
• Query databases efficiently using Spring Data JPA patterns
• Transform data between layers using MapStruct automation
• Apply business logic through properly layered service methods
• Test and verify endpoints during development

Who Should Take This Course

Java developers ready for backend specialization. You need Java fundamentals—classes, objects, basic Spring concepts. We’ll teach the Spring Boot patterns, REST principles, and architectural decisions that move you from junior to mid-level.

Perfect if you’re:

• Moving from frontend to full-stack development
• Transitioning from other frameworks to Spring Boot
• Building portfolio projects that demonstrate real capability
• Preparing for backend developer interviews
• Working professionally but need structured API training

Not right if: You’re completely new to Java or programming. Get those fundamentals first, then come back.

How You’ll Learn

Every lesson includes code you write yourself. You’ll make mistakes. You’ll debug them. You’ll figure out why that validation failed or why your query returned nothing. That’s how you learn—by doing, not watching.

The event management domain mirrors real complexity. Events have dates, statuses, and business rules—exactly what you’ll face in e-commerce, booking systems, or social platforms. The patterns transfer directly.

By the final lesson, you’ll have a deployable API you can test with curl or Postman, show in your portfolio, and discuss intelligently in technical interviews. More importantly, you’ll understand the architectural decisions behind it.
