How to add a logger in mapstruct without having Sonar yelling at me?

Question

In a mapper interface , I have created a default method to map a string to an enum using a bunch of switch/case.

@Mapper(unmappedTargetPolicy = ReportingPolicy.WARN, componentModel="spring", nullValueCheckStrategy = NullValueCheckStrategy.ALWAYS)
public interface ContractMapper {

Logger LOGGER = LogManager.getLogger(ContractMapper.class);

all the mappingstuff...

@Named("getEnum")
default statusEnum getStatusEnum(String status){

    if (status == null){
        return statusEnum.NoStatus;
    } else {

        switch (status) {
        case ...

        default:
            LOGGER.warn("unknown  status {}", status);
            return statusEnum.NoStatus;


        }
    }

I need a logger for when the mapping fail, is there a way to have one without sonar yelling at me because it is not private?

You can always suppress the particular sonar rule for your mapper. If you can't do that then you could use an abstract class instead of an interface.

e.g.

@Mapper(unmappedTargetPolicy = ReportingPolicy.WARN, componentModel="spring", nullValueCheckStrategy = NullValueCheckStrategy.ALWAYS)
public abstract class ContractMapper {

    protected static final Logger LOGGER = LogManager.getLogger(ContractMapper.class);

//...
}
