MapStruct is a complete Java Bean Mapper framework. Based on Annotation Processor (APT) mechanism to generate mappers for the individual Java beans mappings. The generated mappers are real Java-based classes that can also be debugged in the runtime. The MapStruct processor itself uses an interface/abstract class as a starting point of mappings creation (can also contain individually-matched property mapping implementations).

* annotation-based mappings processing mechanism
* wide range of available mapping operations (with more complexity apart from Orika/Dozer)
* can be debugged in runtime in order to validate the end-to-end object mappings

* additional interfaces/abstract classes needed to handle the mapping mechanism
* high performance and universal applicability
