list validation example

[masoudniki]

hey is it possible to add an list validation example? i mean for example in the SignupRequest class its possible to set list of Address for the user

i have tried like code below

  @NotNull(message = "The address is required.")
  public List<   @Valid AddressDTO> address;

but the problem is when spring try to validate it throws an exception with following trace
