Building simple CRUD services with Spring Data REST - Andreas Bräu

Video from Devoxx Poland 2019. Imagine you want to build a simple web service, providing an API for CRUD (Create, Read, Update, Delete) operations. You need to connect to databases create database-specific queries build query statements create controllers analyse results sets You see, that's a lot of boilerplate. Using Spring Boot and Spring Data helps you reducing this boilerplate. You don't need to care on database connections and queries anymore and use Spring Data repositories instead of query statements. The auditing feature helps to keep consistency. With Spring Data REST you can even do more. It uses a Domain-class centric approach to repository interactions. You only need to define what's really important - the domain classes. Domains created with Spring Data REST generate controllers and their dependencies. On top you get HATEOAS links you need to walk through your data.
