Spring Boot 4 REST API Projects

Build Real-World Java Backends with PostgreSQL, Spring Data JPA, Spring Security, Testing, and Docker

Stop following endless tutorials. Start building real Java backend applications.

Ready to turn your Java knowledge into practical backend development skills?

Spring Boot 4 REST API Projects takes you beyond basic examples with three hands-on applications that teach you how to build, secure, test, and prepare modern REST APIs for deployment.

Using Spring Boot 4 and Java 21, you'll develop real-world backend features while learning the tools and techniques used by professional Java developers.

1. Task Management API - Create REST endpoints with CRUD operations, PostgreSQL persistence, validation, pagination, and error handling.

2. Inventory and Order Management API - Build product and order workflows using Spring Data JPA, database relationships, transactions, and optimistic locking.

3. Secure Support Ticket API - Implement JWT authentication, OAuth2 resource-server integration, role-based authorization, and protected API endpoints.

• Spring Boot 4: REST controllers, services, and clean backend architecture.

• PostgreSQL & Spring Data JPA: Database design, relationships, queries, and Flyway migrations.

• Spring Security: JWT authentication, authorization, and API protection.

• Professional Testing: JUnit Jupiter, Mockito, MockMvc, and Testcontainers.

• Docker & Deployment: Containerization, Docker Compose, and GitHub Actions.

Java beginners with basic programming knowledge, aspiring backend developers, students, and programmers who want to build practical Spring Boot applications.

No previous Spring Boot experience required.
