ChatGPT for Java Spring Boot Developers: Build a Spring Boot App with CRUD REST APIs

ChatGPT for Java Developers: In this video, i am gone show you how to build a Spring Boot App with CRUD REST APIs using a single prompt in ChatGPT. Prompt used in this video shared below: Task: Build a Spring Boot App with CRUD REST APIs Prompt: Act as a professional Java Spring Boot developer. I want to generate a complete Spring Boot 3.4+ application using Java 21 that implements CRUD REST APIs for a resource called {{EntityName}}. 1. Project Setup ○ Use Spring Boot 3.5+, Java 21, and Maven ○ Add dependencies: spring-boot-starter-web spring-boot-starter-data-jpa Database: MySQL (PostgreSQL or Oracle or H2) lombok (optional) or records 2. Entity & Data Layer ○ Create a JPA entity named {{EntityName}} with fields: {{fieldList}} Use @jakarta.persistence annotations (@Entity, @Id, @GeneratedValue) ○ Create {{EntityName}}Repository interface extending JpaRepository 3. Service Layer Create a {{EntityName}}Service interface with standard CRUD methods Create {{EntityName}}ServiceImpl implementing the interface Use @Service annotation Handle ResourceNotFoundException where needed 4. Controller Layer ○ Create {{EntityName}}Controller annotated with @RestController and @RequestMapping("/api/{{entityPlural}}") ○ Implement REST endpoints: GET /api/{{entityPlural}} – get all GET /api/{{entityPlural}}/{id} – get one POST /api/{{entityPlural}} – create PUT /api/{{entityPlural}}/{id} – update DELETE /api/{{entityPlural}}/{id} – delete ○ Use @PathVariable, @RequestBody, and proper HTTP status codes 5. Exception Handling ○ Create a ResourceNotFoundException class ○ Create a global exception handler using @RestControllerAdvice and @ExceptionHandler 6. Configuration ○ Use application.properties for MySQL config (H2 or PostgreSQL) ○ Enable H2 console (optional) Additional Expectations: ○ Follow layered architecture: controller → service → repository ○ Use ResponseEntity for responses ○ Return standard status codes: 200, 201, 204, 404 ○ Use Lombok annotations (@Getter, @Setter, @AllArgsConstructor, @NoArgsConstructor) if applicable ○ Use latest best practices (avoid deprecated APIs) #chatgpt #java #springboot
