Sample Spring API Validation Project

This project demonstrates some API validation patterns for Spring Boot Web Applications.

This project accompanies my blog post: Validating Requests in Spring Boot 3.
It supersedes and builds on Validating Requests in Spring Boot which was written for Spring Boot 2. If you are looking for a reference for validation in Spring Boot 2, please check out the release/spring-boot-2 branch of this repo.

Getting started

The sample application is built with Gradle and uses the Gradle Wrapper to ensure a consistent build environment. Build the Spring Boot application with the following command:

./gradlew clean build
