Spring webflux bean validation not working

Question

I am trying to use bean validation in Webflux. This is what I have so far:

@PostMapping(\"contact\")
fun create(@RequestBody @Valid contact: Mono)         


        

Answer 1

You need to also add bindingResult: BindingResult to as an extra parameter. When the method begins you can do something like bindingResult.isValid(). We use an aspect over all controller methods to return an error message with the validation errors to the user.
