Questions tagged [mapstruct]

MapStruct is a code generator for creating efficient, type-safe bean-to-bean mappings in Java.

MapStruct generates bean mapping code at compile time by means of a JSR 269 annotation processor.
The generated code is fast (no reflection or byte code generation at runtime), type-safe (code is generated from typed, domain-specific interfaces) and dependency-free.
