这个问题是由延迟加载引起的。在任务的本质中，有一个名为“resultImage”的字段。此字段包含一个大图片，当卸载所有任务对象时，我不想卸载它。Map程序将Task对象转换为DTO对象时发生错误。
错误日志;
enter image description here
任务实体：

@Entity
@Table(name = "TASKS", schema = "main")
@Builder
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
public class Task {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @NotNull
    @OneToOne(fetch = FetchType.EAGER,cascade = CascadeType.ALL)
    @JoinColumn(name = "USER_ID", referencedColumnName = "id")
    private User user;

    @OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinColumn(name = "RESULT_IMAGE_ID", referencedColumnName = "id")
    private Image resultImage;

    @OneToOne(fetch = FetchType.EAGER,cascade = CascadeType.ALL)
    @JoinColumn(name = "PREVIEW_RESULT_IMAGE_ID", referencedColumnName = "id")
    private Image previewResultImage;
}

图像实体：

@Entity
@Table(name = "IMAGES",schema = "main")
@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
public class Image {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @NotNull
    @Column(name = "DATA")
    @Lob
    private byte[] data;

}

DTO级：

@Data
@Builder
public class ResponseDTO {

    private Long taskId;

    private String sampleImageData;

    private String imagePreviewResultData;
}

发生错误的方法：

public List<ResponseDTO> getAllTasks(Long userId) {

        List<Task> tasks = taskRepository.findAllByUserId(userId);

        return tasks.stream().
                map(Mapper.INSTANCE::taskToResponseDTO).
                collect(Collectors.toList());
    }

Map器中的变换方法：

@org.mapstruct.Mapper(unmappedTargetPolicy = ReportingPolicy.IGNORE)
public interface Mapper {

    Mapper INSTANCE = Mappers.getMapper(Mapper.class);

    @Mapping(target = "taskId", source = "id")
    @Mapping(target = "sampleImageData", source = "imageMetadata.sampleImage.data",qualifiedByName = "dataToBase64")
    @Mapping(target = "imagePreviewResultData", source = "previewResultImage.data",qualifiedByName = "dataToBase64")
    ResponseDTO taskToResponseDTO(Task task);
}

我尝试禁用未配置字段的Map，但没有帮助。
我会很高兴任何帮助！
