Re: [mapstruct-users] Can't generate mapping method from non-iterable type to iterable type. - Error
Christian
Hi Priya,
as the error said, you can't map from a non-iterable to a List. Could you give a short outline what kind of implementation you expect?
I assume you have to implement this mapping method on your own
(see https://mapstruct.org/documentation/stable/reference/html/#adding-custom-methods),
but in this method you can refer to other mapping methods, e. g.
if your Identity has a different object that needs to be mapped
you can define a mapping method that MapStruct will generate and
use this in your self implemented method.
Best regards,
Christian
Hi,--
I need to manipulate a list<AccountToIdentityRoleCollection> from this Identity object and frame List<PersonToBillingArrangementEdge> and map it to List<PersonToBillingArrangementEdge>
i tried the below,
@Mappings({
@Mapping(target="billingArrangements", expression = "java(MapperUtil.getBillingArrangements(identity))"),
})
List<PersonToBillingArrangementEdge> mapPersonBillingArrangementsFromIdentity(Identity identity);
I am getting the below error
Can't generate mapping method from non-iterable type to iterable type.
List<PersonToBillingArrangementEdge> mapPersonBillingArrangementsFromIdentity(Identity identity)
I have the logic of extracting the List<PersonToBillingArrangementEdge> and framing list<AccountToIdentityRoleCollection> in getBillingArrangements method in MapperUtil class which I am importing in this Mapper.
Can you please let me know how to resolve this issue. If this is not the rightway, then how to go about it.
Thanks
Priya
