Prompting Playbook for Spring Boot

• Specify 'Spring Boot 3' with 'Java 17+' or 'Java 21' to get modern features like records for DTOs and Jakarta EE namespaces
• Mention 'Spring Data JPA' vs 'Spring Data MongoDB' vs 'Spring Data R2DBC' for the correct repository and query patterns
• Include 'with Bean Validation' to get @Valid, @NotNull, @Size annotations on DTOs and controller parameters
• When requesting security, specify 'Spring Security 6 with SecurityFilterChain' to avoid deprecated WebSecurityConfigurerAdapter patterns
• Ask for 'Java records as DTOs' to get modern, immutable data transfer objects instead of verbose POJO classes

Patterns AI Should Follow in Spring Boot

• Layered architecture with @RestController, @Service, and @Repository for separation of concerns
• Spring Data JPA repositories with derived query methods and custom @Query for complex lookups
• DTOs as Java records with Bean Validation annotations for request/response transformation
• Global exception handling with @RestControllerAdvice and @ExceptionHandler methods
• Spring Security with SecurityFilterChain beans, JWT filters, and method-level @PreAuthorize
• Application properties and profiles for environment-specific configuration management

REST Controller with Validation and Exception Handling

A Spring Boot REST controller with Bean Validation, service layer delegation, and global exception handling.

// ProductController.java
@RestController
@RequestMapping("/api/products")
@RequiredArgsConstructor
public class ProductController {

    private final ProductService productService;

    @GetMapping
    public Page<ProductResponse> list(
            @RequestParam(defaultValue = "0") int page,
            @RequestParam(defaultValue = "20") int size,
            @RequestParam(required = false) String category) {
        return productService.findAll(category, PageRequest.of(page, size));
    }

    @PostMapping
    @ResponseStatus(HttpStatus.CREATED)
    @PreAuthorize("hasRole('ADMIN')")
    public ProductResponse create(@Valid @RequestBody CreateProductRequest request) {
        return productService.create(request);
    }

    @GetMapping("/{id}")
    public ProductResponse findById(@PathVariable Long id) {
        return productService.findById(id);
    }
}

// CreateProductRequest.java
public record CreateProductRequest(
    @NotBlank @Size(max = 200) String name,
    @NotNull @Positive BigDecimal price,
    @Size(max = 2000) String description,
    @NotNull Long categoryId
) {}

// GlobalExceptionHandler.java
@RestControllerAdvice
public class GlobalExceptionHandler {
    @ExceptionHandler(NotFoundException.class)
    @ResponseStatus(HttpStatus.NOT_FOUND)
    public ErrorResponse handleNotFound(NotFoundException ex) {
        return new ErrorResponse(ex.getMessage());
    }
}
