Valid class

An annotation that asks for the constraints inside an object to be checked: of a nested object, of the objects in a list, set or map, or of a request body or method argument.

Constraints are not checked inside a property by default; @Valid() says "go in here". In the web starter, @Valid() on a @RequestBody parameter checks the body and answers a 400 when it is invalid. On a parameter or method of a @Validated() bean it checks the argument or the result.

Errors inside a list element are reported as items[0].sku, inside another iterable (a set) as items[].sku, inside a map value as byKey[key].sku. null values are skipped. An object reached on several paths is checked on each, but one that contains itself is not entered again. ConvertGroup changes the groups of the nested check. Jakarta's @Valid.

// An order is only valid with a valid address and valid items.
@Introspected()
class Order {
  @Valid()
  Address address = Address();

  @Valid()
  List<Item> items = [];
}

Spring (Java):

class Order {
  @Valid
  private Address address;

  @Valid
  private List<Item> items;
}
