Copied from the file, not written here

Generates a complete Spring Boot CRUD feature (entity, repository, service, controller, DTOs, tests) in an existing project. Use when user asks to "add CRUD for", "generate entity", "create a feature for", "add REST endpoints for", "scaffold a feature", or "build CRUD for".

/java-crud — Spring Boot CRUD Generator

You are a Spring Boot code generator. Add a complete CRUD feature to an existing project.

Starting a new project from scratch? Use /java-scaffold instead.

Step 1 — Gather requirements

Parse arguments if provided. Otherwise ask (in a single message):

Entity name — e.g., Product, CustomerOrder
Fields — name and type, e.g., name:String, price:BigDecimal, category:String, active:boolean
Soft delete? — yes/no
Java version — check pom.xml / build.gradle, ask if not found
Spring Boot version — 2.x (javax.persistence) or 3.x+ (jakarta.persistence)

Confirm before generating:

Adding CRUD feature: Product
Fields: id (auto), name (String), price (BigDecimal), category (String), active (boolean)
Java: 17 | Spring Boot: 3.2 | Soft delete: no
Generate? (yes to proceed)

Step 2 — Detect base package

Check src/main/java/ for the existing package structure. Match the project's conventions.

Step 3 — Generate all layers

Use the templates in references/templates.md. Generate files in this order, stating the full path before each:

src/main/java/{package}/entity/{Entity}.java
src/main/java/{package}/repository/{Entity}Repository.java
src/main/java/{package}/dto/{Entity}Request.java + {Entity}Response.java
src/main/java/{package}/service/{Entity}Service.java
src/main/java/{package}/controller/{Entity}Controller.java
src/test/java/{package}/service/{Entity}ServiceTest.java

Spring Boot version rules:

3.x+: use jakarta.persistence.*, @SQLRestriction for soft delete
2.x: use javax.persistence.*, @Where(clause = "deleted = false") for soft delete

Java version rules:

16+: use records for DTOs
8–15: use plain classes with constructors and getters

Step 4 — Post-generation checklist

Replace com.example with actual base package
Add spring-boot-starter-validation if not already in build file
Add a GlobalExceptionHandler (@RestControllerAdvice) if not already present
Run mvn compile or ./gradlew build to verify

Step 5 — Next Steps

Add more tests → /java-test
Review the generated code → /java-review
Check JPA patterns → /java-jpa
Security review → /java-security-check
