Spring Boot JPA: Native Queries, Criteria & Specification API Explained
Are your Spring Boot repositories filled with messy, unreadable dynamic SQL strings using StringBuilder? There is a much better, enterprise-standard way to handle complex search filters!
In this deep dive into Advanced JPA Querying, we explore the exact differences between Native Queries, the Criteria API, and the Specification API. We look at when you should break the ORM rules and write pure SQL, and how to manually map partial query results to Object[] arrays and DTOs. Then, we expose the boilerplate nightmare of the Criteria API and fix it using Spring Data's beautiful Specification API.
If you are building dynamic Admin Dashboards or Search APIs, this is the only tutorial you need. Stick around until the end for the top architectural rules and killer Java interview statements!
