The defaultExpression can be used to specify a Java expression providing a value that should be used if the source field is null. In order to achieve what you want you will have to define a custom method where you are going to ignore the data field explicitly and then use @IterableMapping (qualifiedBy) or @IterableMapping (qualifiedByName) to select the required method.

IGNORE: no output or errors In order to ignore unmapped properties and get no output warnings, we should assign the IGNORE value to the unmappedTargetPolicy.

Many of us would like to use MapStruct alongside Project Lombok to take advantage of automatically generated getters, setters. MapStruct provides many parameters that can be provided to the @Mapping annotation, each influencing the code that will be generated in a different way.
