public record ProductRequest(@NotBlank(message="Name is mandatory") @Size(max=120,message="Name must be at most 120 characters") String name, @NotNull(message="Price must be provided") @DecimalMin(value="0.01",inclusive=true,message="Price must be greater than 0") @Digits(integer=10,fraction=2,message="Price must have at most 2 decimal places") BigDecimal price) extends Record
Request DTO used to create or update a Product.

Why a DTO? Keeps the HTTP contract stable and safe, decoupled from the JPA entity. Validation annotations ensure early, actionable feedback for clients.

Example (JSON):


 {
   "name": "Coffee Mug",
   "price": 12.99
 }

Usage (Controller):


 @PostMapping("/products")
 public ResponseEntity<ProductResponse> create(@Valid @RequestBody ProductRequest req) {
     Product saved = productService.create(new Product(req.name(), req.price()));
     return ResponseEntity
         .created(URI.create("/products/" + saved.getId()))
         .body(new ProductResponse(saved.getId(), saved.getName(), saved.getPrice()));
 }
