例如,我有一个带有字段的映射类,该字段未在映射类中显示。
我要映射的课程,其中:
@Entity
@Table(name = "t_connection")
@Getter @Setter
@EqualsAndHashCode
public class ConnectionEntity {
@NotNull
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
protected UUID id;
...
}
我要映射的课程,其中:
@ApiModel
@Getter
@Setter
@NoArgsConstructor
public class ConnectionDto {
@ApiModelProperty
private LocalDateTime createAt;
...
// Other fields without id field
}
我的映射器如下:
@Mapper(componentModel = "spring",
unmappedTargetPolicy = ReportingPolicy.ERROR,
unmappedSourcePolicy = ReportingPolicy.ERROR)
public interface CallMapper {
@IterableMapping(qualifiedByName = "map")
List<ConnectionDto> map(List<ConnectionEntity> connectionEntities);
ConnectionDto map(ConnectionEntity connectionEntity);
}
我想知道,当未映射特定字段时,禁用unmappedSourcePolicy
是不可行的。有什么建议吗?
答案 0 :(得分:1)
如果我了解您。.您要控制不想映射的源属性吗?
在这种情况下,请尝试:
@BeanMapping#ignoreUnmappedSourceProperties
所以:
@Mapper(componentModel = "spring",
unmappedTargetPolicy = ReportingPolicy.ERROR,
unmappedSourcePolicy = ReportingPolicy.ERROR)
public interface CallMapper {
@IterableMapping(qualifiedByName = "map")
List<ConnectionDto> map(List<ConnectionEntity> connectionEntities);
@BeanMapping( ignoreUnmappedSourceProperties={"id"} )
ConnectionDto map(ConnectionEntity connectionEntity);
}
不需要指定列表映射,除非您需要外部映射。MapStruct会为您生成一个列表映射。如果您需要外部列表,则可能不需要限定符。 。通用+列表就足够了
