Get smart with MapStruct
summary
MapStruct generates plain Java mapping code at compile time as an annotation processor, avoiding reflection and runtime libraries. It reports unmapped properties as compile errors if configured, compiles as fast as hand-written mappers in independent benchmarks, and supports nested source mappings, custom formatters, qualifier methods, collection and update mappings, Spring/CDI injection and builder support. Generated mappers instantiate via a factory or DI and the generated code is easy to debug and unit test.
