JSR 303: How to Validate a Collection of annotated objects?

April 24, 2023 by Tarik

Yes, just add @Valid to the collection.

Here is an example from the Hibernate Validator Reference.

public class Car {
  @NotNull
  @Valid
  private List<Person> passengers = new ArrayList<Person>();
}

This is standard JSR-303 behavior. See Section 3.1.3 of the spec.
