Map Iterable to Object Containing Iterable With Mapstruct

Date: 2024-10-18

This article demonstrates using MapStruct, a Java annotation-based mapper, to convert an Iterable (like a list of Product entities) into a single object (e.g., a ProductSummaryDTO). MapStruct doesn't directly support this, so the article shows how to create a custom mapping method to aggregate data from the Iterable into the target object. This approach is useful for summarizing data from collections into a single, non-iterable representation. The example uses Product and ProductSummaryDTO classes to illustrate the process.
