MapStruct

Multi-layered applications often require to map between different object models (e.g. entities and DTOs). Writing such mapping code is a tedious and error-prone task. MapStruct aims at simplifying this work by automating it as much as possible.

In contrast to other mapping frameworks MapStruct generates bean mappings at compile-time which ensures a high performance, allows for fast developer feedback and thorough error checking.

1. public class Car {
2.  
3. private String make;
4. private int numberOfSeats;
5. private CarType type;
6.  
7. //constructor, getters, setters etc.
8. }

1. public class CarDto {
2.  
3. private String make;
4. private int seatCount;
5. private String type;
6.  
7. //constructor, getters, setters etc.
8. }

Here we define the Mapper. So after compilation the carToCarDto method is implemented as simple java code.

1. @Mapper 1
2. public interface CarMapper {
3.  
4. CarMapper INSTANCE = Mappers.getMapper( CarMapper.class ); 3
5.  
6. @Mapping(source = "numberOfSeats", target = "seatCount")
7. CarDto carToCarDto(Car car); 2
8. }
