@SubclassMapping not working with @Mapping nested properties and target all #3126
Description
Expected behavior
It should be able to map the nested properties from source to target subclass.
Usage
@SubclassMapping(source = HomeAddressDO.class, target = HomeAddressResponseDto.class)
@SubclassMapping(source = OfficeAddressDO.class, target = OfficeAddressResponseDto.class)
@Mapping(source = "auditable", target = ".")
AddressResponseDto toDto(AddressDO addressDo);Actual behavior
MapStruct complains the following:
No property named "addressDo.auditable.createdBy" exists in source parameter(s). Did you mean "auditable"?
Steps to reproduce the problem
I have created a reproduce at here
In summary, this is the setup
public abstract class AddressDO {
public abstract AddressDOBuilder<?, ?> toBuilder();
private String id;
private Auditable auditable;
}
public class Auditable {
private String createdBy;
private LocalDateTime createdAt;
}
public class HomeAddressDO extends AddressDO {
// some fields
}
public class OfficeAddressDO extends AddressDO {
// some fields
}
public interface AddressResponseDto {}
public record HomeAddressResponseDto(String id, String street, String postalCode, String unit, String createdBy, String createdAt) implements AddressResponseDto {}
public record OfficeAddressResponseDto(String id, String building, String street, String postalCode, String unit, String createdBy, String createdAt) implements AddressResponseDto {}
@Mapper(
componentModel = MappingConstants.ComponentModel.SPRING,
subclassExhaustiveStrategy = SubclassExhaustiveStrategy.RUNTIME_EXCEPTION
)
public interface AddressMapper {
@SubclassMapping(source = HomeAddressDO.class, target = HomeAddressResponseDto.class)
@SubclassMapping(source = OfficeAddressDO.class, target = OfficeAddressResponseDto.class)
@Mapping(source = "auditable", target = ".") // < offending line
AddressResponseDto toDto(AddressDO addressDo);
