Spring boot: @Valid not working with @RequestHeader

I'm really struggling to combine @Valid with @RequestHeader. Might this be not supported or is there a way to enable it? I couldn't find useful information about that...

When I annotate the whole controller with @Validated it works, so it is not a big issue. However, I feel like it should work with @Valid as well, so I wanted to know if I'm missing something here.

Code example:

    @GetMapping("/validationControllerHeader")
    public String validationControllerHeader(@Valid @RequestHeader @Pattern(regexp = "[a-z]{3}[0-9]+") String someheader) {
        return someheader;
    }

I'm using @Valid in the same test controller for query parameters and body validation too and there it works, so the issue is only present with headers.

Using spring boot 2.3.1.RELEASE

You are definitely supposed to use @Validated in your controller class, as it indicates that the validation is meant to be performed in that class. From the documentation:

To be eligible for Spring-driven method validation, all target classes need to be annotated with Spring’s @Validated annotation, which can optionally also declare the validation groups to use.

And, as you are using @Pattern (which is a Bean Validation annotation), you don't need @Valid.
