是否可以将 ArrayList 数据映射到 DTO？

Question

我尝试将数组列表数据转换为 DTO 模式，但出现类似

的错误 <块引用>

Caused by: org.hibernate.MappingException: 无法确定类型 对于：java.util.List，在表：BillingDetailsDTO，对于列： [org.hibernate.mapping.Column(billingDetailsList)]

查询

@Query("select new BillingDetailsDTO (b.id,b.billingDetails) "
        + "from Billing2 b "
        + "where b.id = :billingId")
List<BillingDetailsDTO> selectBillingDetails(Integer billingId);

DTO 模型

@Entity
public class BillingDetailsDTO {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer billingId;
private List<CustomBillingDetails2> billingDetailsList;

public Integer getBillingId() {
    return billingId;
}

public List<CustomBillingDetails2> getBillingDetails() {
    return billingDetailsList;
}

public BillingDetailsDTO(Integer billingId, List<CustomBillingDetails2> billingDetailsList) {
    super();
    this.billingId = billingId;
    this.billingDetailsList = billingDetailsList;
    }
}
