Gradle Spring mvc validation data class recursive Kotlin

Question

I need to create a recursive validation to be able to validate PizzaCreate Object and base attribute in recursive mode using Kotlin. The test should return 400 but it returns 200 ok (Base name size must be greater than 2):

data class Base(@field:Length(min = 2, max = 100) val name:String)    

data class PizzaCreate(
    val id: Long,
    @field:Length(min = 2, max = 100) val name: String,
    val description: String,
    val price: Int,
    @Valid val base: Base

)

@RestController
@RequestMapping("/pizza")
class PizzaController(val pizzaService: PizzaService) {

@PostMapping
fun post(@RequestBody @Valid pizza: PizzaCreate) = pizzaService.addPizza(pizza)

}

  @Test
fun `should add pizza `() {

    val pizza = easyRandom.nextObject(PizzaCreate::class.java).copy(id = 1, name="aaa", base = Base(""))
    val pizzaOut = PizzaOut(id=1,name=pizza.name,description = pizza.description,price = pizza.price)

    `when`(pizzaService.addPizza(pizza)).thenReturn(pizzaOut.toMono())

    webTestClient.post()
            .uri("/pizza")
            .bodyValue(pizza)
            .exchange()
            .expectStatus().isBadRequest
            .returnResult<PizzaOut>().responseBody
}

base.name is `aaa` so it's correct. Try with base.name equal `a`, then you should see 400. — Ice, Feb 24 '21 at 13:44
base = Base("") base name is "" not aaa (aaa is the pizzaCreate name value). I am trying to force base name recursive validation — CRISTIAN ROMERO MATESANZ, Feb 24 '21 at 16:20

Validation on Base should be @field:Valid val base: Base instead of @Valid val base: Base

field: specifies the annotation is applied on the field not construc

It works like a charm. I thought field: wasn't a must with recursive validation. A lot of thanks for your fast response. – CRISTIAN ROMERO MATESANZ Feb 24 '21 at 20:44
