I'm working in spring boot with Mappstruct and Lombok. When I use the Mapper anotation to auto implement the mapper class, the anotation is not generating correcty the mapper implementation for my classes.
This is POM.xml

This my 2 objects to map one to other: 1st one:
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
@SuppressWarnings("unused")
public class User {
private Integer id;
private String usrLogin;
private String pass;
private String name;
private String surname;
private Boolean enabled;
}
2nd one:
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
@SuppressWarnings("unused")
public class UserRequest {
private Integer id;
private String usrLogin;
private String pass;
private String name;
private String surname;
private Boolean enabled;
}
My Mapper inteface:
import com.domotichouse.app.SpringDomoticHouse.application.dto.User;
import com.domotichouse.app.SpringDomoticHouse.rest.dto.UserRequest;
import org.mapstruct.Mapper;
import org.mapstruct.factory.Mappers;
@Mapper
public interface UserRestMapper {
UserRestMapper MAPPER = Mappers.getMapper(UserRestMapper.class);
User toAplication(UserRequest request);
}
And here is how the anotation implements the interface:
import com.domotichouse.app.SpringDomoticHouse.application.dto.User;
import com.domotichouse.app.SpringDomoticHouse.rest.dto.UserRequest;
public class UserRestMapperImpl implements UserRestMapper {
public UserRestMapperImpl() {
}
public User toAplication(UserRequest request) {
if (request == null) {
return null;
} else {
User user = new User();
return user;
}
}
}
As you can see the Mapper dont map anything. PD: I have the lombok pluging installed and the @Data and @Builder anotations work as expected
