🚀 Session 83 – Spring Data JPA Derived Query | findByUniverse() Explained
#SpringBoot #SpringDataJPA #DerivedQuery #JavaFullStack #RESTAPI
Welcome to Session 83 of the Java Full Stack Made Easy series!
In this session, we explore one of the most powerful features of Spring Data JPA — Derived Queries.
We implement a custom query method:
findByUniverse(String universe)
Without writing any JPQL or SQL manually! 🎯
Spring automatically generates the query just from the method name.
We continue working with our SuperHero entity having:
id
name
universe
power
