Question

不确定这里会发生什么，但是当我执行 mvn clean install 时，我收到以下错误：

不兼容的类型：capture#1 of ?无法转换为 com.sweetchoice.report.entities.WhoDelivers

映射器类：

@Mapper(uses = {BaseJournalMapper.class})
public interface WhoDeliversMapper {

    WhoDelivers dtoToEntity(WhoDeliversDto whoDeliversDto);

    WhoDeliversDto entityToDto(WhoDelivers whoDelivers);
}

实体类：

@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Table(name = "who_delivers")
public class WhoDelivers extends BaseJournalEntity{

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(columnDefinition = "serial")
    private Long id;

    private String name;
}

BaseJournalEntity/BaseJournalDto：

@Getter
@Setter
@SuperBuilder
@AllArgsConstructor
@NoArgsConstructor
@MappedSuperclass
public class BaseJournalDto {

    private LocalDateTime createdAt;
    private Long createdBy;
    private LocalDateTime updatedAt;
    private Long updatedBy;
}

DTO 类：

@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
public class WhoDeliversDto extends BaseJournalDto{

    private Long id;

    private String name;

}

最后是 pom.xml:

我使用的是 Java 11、MapStruct 1.4.1.Final 和 Lombok 1.18.16
