Spring Boot Bean Validation In HashMap Not Working

Question

I am creating a REST controller which shall take a list of Dtos. It all works but the validation is not working, therefore it fails during persistence only.

My code:

@Valid @RequestBody HashMap<String, MyDto> myDtoMap

And unfortunately the MyDto does not get validated.

I also tried this way:

@Valid @RequestBody HashMap<String, @Valid MyDto> myDtoMap

Please try :

annotate your controller with :

@RestController
@Validated

Then you can validate you class with :

@RequestBody HashMap<String, @Valid MyDto> myDtoMap

Thank you. You were right with `@Validated`. Do you know why it is necessary? I think `@Valid` should be enough? – CodeWarrior May 22 '21 at 20:17
