如何告诉 MapStruct“不”使用 Lombok Builder？

Question

我有以下类和映射器来映射它们。 如何将 Mapstruct 配置为“不”使用 Lombok 构建器？ （不删除@Builder 注释）？ 在使用最新版本的 Lombok 和 mapstruct 时，mapstruct 在使用 @Builder 注解时会自动使用 Builder。我找不到禁用它的方法，因为我需要 @AfterMapping 方法中的实例，因为构建器没有公开所有必需的方法（此用例中不允许使用 @SuperBuilder）

@Entity(name = "user_details")
@Data
@Builder
public class User extends AuditableEntityBase {

    @Version
    @NotNull
    private Integer version;

    @NotNull
    private String name;

    @NotNull
    private String email;

    @NotNull
    private Address address; // Just another Class containing another class that is mapped as well.

}

@Value
@Builder
public class UserDto extends AuditableEntityBaseDto {

    @NotNull
    private Integer version;

    @NotNull
    private String name;

    @NotNull
    private String email;


    @NotNull
    private AddressDto address;
}


@Mapper(componentModel = "spring")
class UserRestMapper {
    public abstract UserDto map(User obj);

}

    @AfterMapping
    public void decorate(User source, @MappingTarget AuditableEntityBase target) {
// Method is never called.
// Method is called in case  the second argument is: "@MappingTarget UserDto.UserDtoBuilder target"
    }

Answer 1

如果您想禁用使用构建器，可以通过将@Builder(disableBuilder = true) 添加到您的@Mapper 来实现。

例如

@Mapper(componentModel = "spring", builder = @Builder(disableBuilder = true))
class UserRestMapper {
    public abstract UserDto map(User obj);

}

注意@Builder来自org.mapstruct包

不知道要禁用它，但为什么不这样做呢？

@Mapper(componentModel = "spring")
abstract class UserRestMapper {
    public abstract UserDto map(User obj);
    
    public UserDto decoratedMap(User obj) {
        UserDto mapped = map(obj);
        // your after mapping logic
        return mapped;
    }
}
