Spring Boot 4 REST APIs: Building Modern REST APIs

Develop Real-Time Spring Boot 4 RESTful Endpoints: CRUD, JWTs, OpenAPI, Swagger, Auth, H2 Embedded DB, MySQL

UPDATED FOR SPRING BOOT 4 AND SPRING 7

Spring Boot 4 is the most popular framework for building enterprise Java applications. Spring Boot 4 includes REST  support to develop scalable backend API development. By developing RESTful endpoints, you can create applications with better code design, securely authenticated scalable solutions, that are all easier to maintain. This course shows you how to take full advantage of Spring Boot's REST support.

You will also use modern development tools such as IntelliJ (free version) and Maven. All of the projects are based on Maven, so you are free to use any IDE tool that you want.

In this course, you will learn how to:

REST API Fundamentals

• Understand REST architecture and principles

• Set up Spring Boot REST controllers

• Build endpoints for CRUD operations

• Use @RestController, @RequestMapping, @PathVariable, and @RequestBody

• Differentiate between GET, POST, PUT, and DELETE methods

• Handle path variables and query parameters effectively

• Leverage @ResponseStatus to control HTTP responses

Connect to Databases with Spring Data JPA

• Integrate with MySQL (and H2 for local dev)

• Use Spring Data JPA repositories

• Map entities with JPA annotations

• Perform custom queries using JPQL and native SQL

• Use projections and DTOs to control data exposure

CRUD Operations

• Create REST endpoints for full CRUD functionality

• Return JSON data using Jackson

• Use @PostMapping, @PutMapping, @DeleteMapping, and @GetMapping effectively

• Build reusable service-layer logic

• Avoid code duplication with generic service/repository patterns

• Handle entity not found scenarios gracefully

• Respond with appropriate status codes for create/update/delete operations

REST Best Practices

• Use proper HTTP status codes

• Path & Query Data Validation

• Object Data Validation

• Apply request validation with @Valid and custom validators

• Structure consistent response models

• Implement global exception handling with @ControllerAdvice

• Leverage @ResponseEntity for flexible responses

• Avoid exposing internal domain objects directly in responses

Secure Your REST APIs

• Add basic authentication with Spring Security

• Secure endpoints by role or path

• Implement JWT authentication (coming soon in course updates)

• Customize login/logout endpoints

• Configure stateless sessions using JWT

• Restrict CORS to specific domains

• BCrypt Hashing for database passwords
