JarCastingmapstruct-spring-plus
It is an enhanced package of mapstruct and spring, which simplifies the use of mapstruct combined with spring. The implementation method refers to the mapstruct-spring-extensions project
Create Dto and Entity
@Data
@AutoMap(targetType = Car.class)
public class CarDto {
private String make;
@AutoMapField(target = "carType")
private String type;
}
@Data
public class Car {
private String make;
private String carType;
}

Use Cases
Inject IObjectMapper in spring, call objectMapper.map(dto, Car.class)
@ExtendWith(SpringExtension.class)
@ContextConfiguration(
classes = {AutoMapTests.AutoMapTestConfiguration.class})
public class AutoMapTests {
@Autowired
private IObjectMapper mapper;
@Test
public void testDtoToEntity() {
var dto = new CarDto();
dto.setMake("M1");
dto.setType("OTHER");
Car entity = mapper.map(dto, Car.class);
assertThat(entity).isNotNull();
assertThat(entity.getMake()).isEqualTo("M1");
assertThat(entity.getCarType()).isEqualTo("OTHER");
}
@ComponentScan("io.github.zhaord.mapstruct.plus")
@Configuration
@Component
static class AutoMapTestConfiguration {
}
}
