MapStruct Problem: binding to a class with getter/Builder classes

I am using MapStruct to bind objects from my LibraryResponse class to my APIResponse class, but I am getting compile warnings that the target properties withVar1, withVar2, … withVar20 are unmapped. My APIResponse class has a builder class with setter methods for the above variables, but I don’t want to manually map each variable with a @Mapping annotation. Is there a way to tell MapStruct to use the getters instead of the builder class?

Yes, you can tell MapStruct to use the getters instead of the builder class by adding componentModel = "spring" to your @Mapper annotation. This will make MapStruct use the getters instead of the builder class to set the properties in your target object.

Here is an example:

@Mapper(componentModel = "spring")
public interface MyMapper {
    APIResponse map(LibraryResponse libraryResponse);
}
