MapStruct's @IterableMapping annotation provides granular control over collection mappings in Java. It enables custom formatting through attributes like dateFormat for converting string dates to LocalDate objects, allows selecting specific mapping methods using qualifiedByName to exclude sensitive fields like passwords, and handles null collections safely with nullValueMappingStrategy to return empty collections instead of null. This eliminates manual boilerplate code for iterating and transforming collection elements.
