Spring and Kotlin: A Winning Combination

on YouTube ↗58m

" summary

Shows concrete Spring + Kotlin code: project generated from start.spring.io, uses the kotlin-spring plugin to auto-open classes, the Jackson Kotlin module for JSON, and a reified extension runApplication. Demonstrates REST controllers, a MockMvc DSL and WebTestClient, Spring Data JPA with H2 and JDBC template row mappers, and coroutine-based web client vs WebFlux. Includes runnable GitHub projects, tests that start a server on a random port and pass, and practical examples of where Kotlin actually simplifies Spring code.
