I want to use annotation validation for beans like I was doing in spring boot

data class NewUser(
    ....
    @field:NotNull @field:Email val email: String,
    ...
)

get(){
   val user = call.receive<NewUser>()
}

So continue to use Spring Boot or directly use one of the validation libraries it uses?

If there a ktor way, so tell me how, or a link

You shouldn't need any annotations to handle a null non-nullable property. Unless you're using gson as your json module (which I don't reccommend), the json module will catch the non value, and Ktor will return a 400.

yeah, I'm using json module,

also want to get the jakerta built-in email validator,
or something similar in ktor
