kotlin and @Valid Spring annotation

Question

I have an entity:

class SomeInfo(
        @NotNull @Pattern(regexp = Constraints.EMAIL_REGEX) var value: String) {
    var id: Long? = null
}

Answer 1

As an alternative to Michal's answer, annotating the getter also works.

class SomeInfo(
    @get:NotNull
    @get:Pattern(regexp = Constraints.EMAIL_REGEX)
    var value: String
) {
    var id: Long? = null
}

The annoying part is, that not using @get: or @field: will annotate the constructor parameter. This is still valid kotlin code (so you don't get an error). It's just useless in these use cases.
