Spring Boot CRUD Generator

Product Introduction

1. Definition: Spring Boot CRUD Generator is an IntelliJ IDEA plugin designed for Java backend development. It automates the creation of production-ready Spring Boot backend layers from JPA entities.
2. Core Value Proposition: This plugin eliminates repetitive CRUD boilerplate code, enabling developers to generate controllers, services, repositories, DTOs, mappers, and security integrations in one click. It accelerates Spring Boot API development while enforcing clean architecture principles.

Main Features

1. Full-Stack CRUD Scaffolding: Generates controllers with REST endpoints (GET/POST/PUT/DELETE), JPA repositories, and service layers directly from JPA entity classes. Uses Spring Data JPA for database interactions and MapStruct for efficient DTO-entity mapping.
2. Built-in Security & Documentation: Integrates JWT-based authentication with role-based access control (RBAC) and auto-generates Swagger/OpenAPI 3.0 documentation. Configures Spring Security for endpoint protection and provides OAuth2-ready token management.
3. Pagination & Auditing Automation: Implements Spring Data pagination for GET endpoints and auto-adds auditing fields (createdBy, modifiedDate) via Hibernate Envers or Spring Data Auditing. Includes global exception handling with @ControllerAdvice for consistent error responses.

Problems Solved

1. Pain Point: Reduces manual coding of repetitive CRUD operations, which typically consumes 30–50% of backend development time. Mitigates human error in boilerplate logic like transaction management and DTO conversions.
2. Target Audience: Java backend developers working with Spring Boot, microservices architects, and teams adopting domain-driven design (DDD) who prioritize rapid prototyping without compromising production standards.
3. Use Cases: Ideal for generating admin panels, MVP backends, or migrating legacy applications to Spring Boot. Essential for projects requiring immediate Swagger docs for client teams or JWT security compliance.

Unique Advantages

1. Differentiation: Unlike generic Spring Initializr or IDE tools, this plugin produces fully functional, layered code (controller-service-repository) with pagination, auditing, and exception handling pre-configured—outperforming basic CRUD generators.
2. Key Innovation: Combines 10+ Spring Boot best practices (e.g., SOLID-compliant service layers, DTO isolation) into a single workflow. Offers optional modules like JWT security without manual dependency setup, reducing integration time by 80%.

Frequently Asked Questions (FAQ)

1. Does Spring Boot CRUD Generator support reactive programming?
   Currently, it focuses on traditional Spring MVC and Spring Data JPA (blocking) architectures. Reactive support (WebFlux/R2DBC) is not included.
2. Can I customize generated code templates?
   Yes, the plugin allows template editing for controllers, services, and DTOs via IntelliJ’s live templates, ensuring alignment with project-specific coding standards.
3. How does it handle database schema changes?
   Regenerating code after JPA entity updates overwrites affected files (e.g., repositories/services) while preserving custom business logic in segregated layers.
4. Is Swagger UI integration included?
   Absolutely. It auto-generates OpenAPI 3.0 specs with endpoint descriptions and request/response models, accessible via /swagger-ui.html.
5. What IDEs besides IntelliJ support this plugin?
   It’s exclusive to IntelliJ IDEA and compatible editions (PyCharm Professional, WebStorm) via JetBrains Marketplace.
