Building a RESTful Web Service with Spring

This Spring guide keeps the first backend task narrow: create a service that responds to an HTTP request with JSON. That limited scope makes the controller, response object, and application startup easier to inspect. It is a first working slice of a Spring application rather than a comprehensive backend engineering course.

What you will learn

• Create a project using the recommended Spring tooling
• Define a REST controller and a response type
• Read request parameters
• Run the service and inspect its JSON response

Who this suits

Useful for a Java programmer beginning Spring Boot who wants a small success before introducing a database or authentication. Familiarity with classes, methods, and a build tool will help. It is also a quick reference when you need to recall how a minimal controller is structured.

Before you enroll

A greeting endpoint has no persistence, meaningful authorization, or operational requirements. Treat those as the next lessons, not as problems solved by the starter application. Use the Java and Spring versions requested by the current guide to avoid unnecessary setup errors.

Free official guide without a completion certificate. The required local development tools are described on the source page.

Put it into practice

Add one validated parameter and check both a valid request and a malformed request using an HTTP client.
