Question: Is it possible to validate using Bean Validation for JsonSubTypes polymorfic deserialization?

[gustavodaquino]

Hello! I have a question regarding the usage of Bean Validation in Kotlin for subtypes in a polymorphic deserialization.
Here's an example that illustrates the scenario:

data class Shape(
    @NotBlank @Pattern(regexp = "SQUARE|CIRCLE") val type: String,
    @JsonTypeInfo(use = NAME, include = EXTERNAL_PROPERTY, property = "type")
    @JsonSubTypes(
        value = [
            Type(value = Square::class, name = "SQUARE"),
            Type(value = Circle::class, name = "CIRCLE")
        ]
    )
    val base: Base
)

data class Square(@Min(1) val side: Int) : Base()

data class Circle(@Min(1) val radius: Int) : Base()

sealed class Base

In the code above, the validation of the type property works fine. However, the validation for the properties of the subclasses is currently being ignored.

I would appreciate any help or guidance you can provide!

im not sure how this is a jackson question, jackson does not perform bean validation.

the validation for the properties of the subclasses...

I think you mean validation is not performed on the value of base property.

If I remember correctly, to get Bean Validation to validate "inside" property value, you need to annotate that property with @Valid.
