How to validate objects that were deserialized with Jackson polymorphic deserialization - spring-boot

Question

Given the following request:
/enterprises-api/{{version}}/enterprises?query={"searchType":"FOUNDERSEARCH","maxResult":"61",...}
OR
/enterprises-api/{{version}}/enterprises?query={"searchType":"NAMEORADDRESSSEARCH","maxResult":"61",...}
I have managed to deserialize query into either a FounderSearch or NameOrAddressSearch object based on the searchType property.
However, Javax validation is ignored because this isn't a toplevel object. How can I resolve this?
Top level object:
#JsonTypeInfo(
use = JsonTypeInfo.Id.NAME,
include = JsonTypeInfo.As.PROPERTY,
property = "searchType")
#JsonSubTypes({
#JsonSubTypes.Type(value = FounderSearch.class, name = "FOUNDERSEARCH"),
#JsonSubTypes.Type(value = NamerOrAddressSearch.class, name = "NAMEORADDRESSSEARCH")
})
public abstract class Query {
public abstract boolean isFounderSearch();
}
One of the sub-level objects:
#Data
public class FounderSearch extends QueryObject {
#Min(1) #Max(60)
private Integer maxResult = 20;
#Pattern(regexp = "\\d{11}")
private String personNumber;
private List<CodeType> functions;
private Boolean activeFunctions;
public boolean isFounderSearch() {
return true;
}
public SearchType getSearchType() {
return SearchType.FOUNDERSEARCH;
}
}

Answer 1

If you add #Valid annotation on nested objects as well it will work.
something like this, above all the fields that have validation constraints.
#Data
public class FounderSearch extends QueryObject {
#Min(1) #Max(60)
#Valid
private Integer maxResult = 20;
#Pattern(regexp = "\\d{11}")
#Valid
private String personNumber;
private List<CodeType> functions;
private Boolean activeFunctions;
public boolean isFounderSearch() {
return true;
}
public SearchType getSearchType() {
return SearchType.FOUNDERSEARCH;
}
}
