Use spring Mapper to map object of Map - Java

I'm facing some difficulties while trying to use Mapper annotation functionality of spring. I would like to use the mapper to map an object of Map in java as follows:

HostCounters : 

@Data
@NoArgsConstructor
@AllArgsConstructor
public class HostsCounters {
    private Map<String,Map<String,Long>> hostsList;
}

Mapper : 

@Mapper(componentModel = "spring")
public interface ResponseMapper {
    GeneralResponse toResponse(SevCount sevCount, HostsCounters hostsList, List<RegDAO> Reg);
}

GeneralRespone:

@Data
@NoArgsConstructor
public class GeneralResponse {
    private List<RegDAO> Reg;
    private HostsCounters hostsList;
    private SevCount sevCount;
}

Error:

Can't map property "java.util.Map> hostsList" to " HostsCounters hostsList". Consider to declare/implement a mapping method

Just use:

@Mapping(source = "hostsList", target = "hostsList")
GeneralResponse toResponse(SevCount sevCount, HostsCounters hostsList, List<RegDAO> Reg);

But I would strongly advise you to get rid of identical names with different meanings:

HostsCounters hostsList -> HostsCounters hostsLists
