A Developer's Guide to Spring Boot 3 - Exploring Modern Practices
This guide will walk you through a project built with Java 21, Spring Boot 3, and Gradle. Our goal isn’t just to write working code - we want to make sure the project is robust, fast, and easy to maintain in the future.
We’ll start with basic setup, then explore database JPA, version control with Liquibase, and Redis caching. After that, we’ll focus on “observability” - learning how to monitor your app’s health using Micrometer and OpenTelemetry (OTLP), and send all monitoring data to Grafana for analysis.
This guide is perfect for developers who want to learn modern Spring Boot 3 practices.
