Bean Validation


The position of the @Valid annotation on reactive types has changed in 2024.2. Until then the @Valid was placed on the generic type of the reactive wrapper, like this:

    void postFooFlux(@Parameter Flux<@Valid Bar> body);

Unfortunately validation did not happen. Spring needs the @Valid annotation on the reactive wrapper to trigger the validation. Therefore @Valid is placed by default on the reactive wrapper:

    void postFooFlux(@Parameter @Valid Flux<Bar> body);

To keep the old behaviour see compatibility.
