This article demonstrates how to use Spring Data R2DBC with Spring Boot 3 to perform reactive 1‑to‑1 and 1‑to‑many database operations, covering environment setup, entity definitions, repository queries, custom converters, and unit testing for full‑stack backend development.
Learn how to integrate Spring Boot WebFlux with R2DBC for reactive database operations, covering R2DBC basics, driver selection, configuration, entity and service implementation, controller endpoints, repository usage, optimistic locking, and practical code examples to build high-performance, non-blocking backend applications.
This guide walks through setting up a Spring Boot 2.7.7 WebFlux project, configuring R2DBC dependencies, defining entity, repository and service layers, writing unit tests, and implementing a full reactive security configuration using WebFlux filters and custom access rules.
