18. Building RESTful APIs Using Java (Spring Boot / Java EE)
RESTful APIs are crucial for web-based systems, leveraging HTTP methods to facilitate communication between client and server. This chapter discusses building RESTful services using Spring Boot and Java EE, exploring how to design endpoints, manage requests and responses, and perform CRUD operations on resources. Key concepts include REST architecture principles, HTTP method usage, and design best practices for optimal API performance.

What we have learnt
- REST stands for Representational State Transfer, focusing on stateless interactions and resource management.
- Spring Boot and Java EE are powerful frameworks for creating RESTful APIs, each with distinct advantages.
- Best practices for designing REST APIs emphasize proper URI structuring, HTTP status code usage, and security measures.
Key Concepts
- -- REST
- An architectural style for designing networked applications, utilizing stateless communication to ensure scalability.
- -- HTTP Methods
- Methods used by RESTful APIs to perform CRUD operations, including GET, POST, PUT, and DELETE.
- -- Spring Boot
- A framework that simplifies building production-ready applications on the Spring framework with auto-configuration and embedded servers.
- -- Java EE (Jakarta EE)
- A set of specifications for enterprise features in Java, including web services and RESTful services through JAX-RS.
- -- Exception Handling
- A mechanism in Spring Boot to manage errors through a centralized approach using ControllerAdvice.
- -- Security in APIs
- Mechanisms like Basic Auth, Token-based Auth (JWT), OAuth 2.0, and HTTPS for protecting API endpoints.
