Get Super Productive with Intellij File Templates

IntelliJ IDEA File Templates let you create custom file scaffolding beyond the default Class/Interface options. The post walks through creating single-file templates for Spring REST Controllers, JPA Entities, and Spring Data JPA Repositories using Velocity template syntax. It then shows how to combine these into a multi-file parent template that generates a full API boilerplate (Entity, Repository, Service, Controller) in one step by entering just the entity name. A bonus tip covers using Structural Search and Replace to refactor @RequestMapping annotations into @GetMapping.
