我的实体类已经标注为：

@SqlResultSetMapping(
     name = "LossDetailsMapping", 
     entities = @EntityResult(
       entityClass = LossDetails.class, 
       fields={ 
        @FieldResult(name = "billId", column = "billId"), 
        @FieldResult(name = "billSrlNum", column = "billSrlNum"), 
        @FieldResult(name = "totalInItems", column = "totalInItems"), 
        @FieldResult(name = "totalInAmount", column = "totalInAmount"), 
        @FieldResult(name = "totalSoldItems", column = "totalSoldItems"), 
        @FieldResult(name = "totalSoldAmount", column = "totalSoldAmount"), 
        @FieldResult(name = "remItems", column = "remItems"), 
        @FieldResult(name = "loss", column = "loss") 
       } 
       ) 
     ) 
public class LossDetails { 
//setter, getter are here 
}

和我的JPA查询是：

LIST_LOSS_PROFIT_DETAILS="SELECT sd_data.bill_id as billId ," 
      + " sd_data.bill_srl_no as billSrlNum ," + " sd_data.total_act_qnt as totalInItems ,"

      + " NVL(ssd_data.sold_act_rt,0) as totalSoldAmount," 
      + " sd_data.total_act_qnt-NVL(ssd_data.sold_qnt,0) as remItems,"

Query query = entityManager.createNativeQuery(LIST_LOSS_PROFIT_DETAILS,LossDetails.class); 
List<LossDetails> lossDtls = query.getResultList();

任何人，你可以帮助我在这段代码中犯了什么错误？

你可以给你的豆吗？ –

您的LossDetails类是否使用@Entity映射？ – Ish

有2种方式来映射结果集本地的SQL查询类的 - 无论是通过@EntityResult和@ConstructorResult

@EntityResult 它可以检索本地SQL查询管理的实体。您可以将通过SQL查询返回的值映射到实体属性。例如，您有一个实体类LossDetails.class并映射到LOSS_DETAILS表。

@Entity 
@Table(name="LOSS_DETAILS) 
public class LossDetails { 
    @Id 
    private Long billId; 

    private String billSrlNum; 

    private Integer totalInItems; 

    private Double totalInAmount; 

    private Integer totalSoldItems; 

    private Double totalSoldAmount; 

    private Integer remItems; 

    private Double loss; 
}

然后，例如，您的本机SQL查询将返回ff。列：

BILL_ID, BILL_SRL_NO, TOTAL_ACT_QNT, TOTAL_ACT_RT, SOLD_QNT, SOLD_ACT_RT, REM_ITEMS, LOSS

请注意，该列名不完全匹配您的实体类LossDetails的属性名称。对于这一点，你需要指定@SqlResultSetMapping这样的：

@SqlResultSetMapping(name="LossDetailsMapping", 
    [email protected](
     entityClass=LossDetails.class, 
     fields={ 
      @FieldResult(name="billId", column="BILL_ID"), 
      @FieldResult(name="billSrlNum", column="BILL_SRL_NO"), 
      @FieldResult(name="totalInItems", column="TOTAL_ACT_QNT"), 
      @FieldResult(name="totalInAmount", column="TOTAL_ACT_RT"), 
      @FieldResult(name="totalSoldItems", column="SOLD_QNT"), 
      @FieldResult(name="totalSoldAmount", column="SOLD_ACT_RT"), 
      @FieldResult(name="remItems", column="REM_ITEMS"), 
      @FieldResult(name="loss", column="LOSS") 
     } 
    ) 
)

如果你的SQL列和实体的属性完全一致的名称相匹配，那么你就需要枚举的字段。就像这样：

@SqlResultSetMapping(name="LossDetailsMapping", 
    [email protected](
     entityClass=LossDetails.class) 
)

注意，有可能是原生SQL查询从另一个表（从映射到实体表不同）选择，只要所产生的列将被映射到每一个实体的属性及其类型是兼容的。

要在创建本机查询时使用声明的结果集映射，只需通过名称引用它即可。下面的例子：

private String LIST_LOSS_PROFIT_DETAILS = "...YOUR NATIVE SQL QUERY HERE..."; 

Query query = entityManager.createNativeQuery(LIST_LOSS_PROFIT_DETAILS, "LossDetailsMapping"); 
List lossDtls = query.getResultList();

@ConstructorResult

如果你的目的仅仅是你的本地SQL的结果映射到一个POJO或bean类，而豆不一定要通过对其进行保存/更新/删除操作进行管理，那么您不需要实体类。您实际上可以将SQL结果集列映射到纯Java对象。我相信这是你想要使用的。使用JPA 2.1版本，您可以通过@ConstructorResult从本机查询构建非实体类型。

下面是一个例子：

public class LossDetails { 

    public LostDetails(Long billId, String billSrlNum, 
     Integer totalInItems, Double totalInAmount, 
     Integer totalSoldItems, Double totalSoldAmount, 
     Integer remItems, Double loss) { 
     this.billId = billId; 
     this.billSrlNum = billSrlNum; 
     this.totalInItems = totalInItems; 
     this.totalInAmount = totalInAmount; 
     this.totalSoldItems = totalSoldItems; 
     this.totalSoldAmount = totalSoldAmount; 
     this.remItems = remItems; 
     this.loss = loss; 
    } 

    private Long billId; 

    private String billSrlNum; 

    private Integer totalInItems; 

    private Double totalInAmount; 

    private Integer totalSoldItems; 

    private Double totalSoldAmount; 

    private Integer remItems; 

    private Double loss; 
}

注意LossDetails只是一个POJO，而不是与@Entity注解。还要注意构造函数的存在。使用@ConstructorResult的sql结果集映射将使用此构造函数从本机SQL查询结果中创建POJO。

每JPA规范：

All columns corresponding to arguments of the intended constructor must be specified using the columns element of the ConstructorResult annotation in the same order as that of the argument list of the constructor.

所以这里有一个样品使用的@ConstructorResult：

@SqlResultSetMapping(name="LossDetailsMapping", 
    classes={ 
     @ConstructorResult(targetClass=LossDetails.class, 
      columns={ 
       @ColumnResult(name="billId", type=Long.class), 
       @ColumnResult(name="billSrlNum", type=String.class), 
       @ColumnResult(name="totalInItems", type=Integer.class), 
       @ColumnResult(name="totalInAmount", type=Double.class), 
       @ColumnResult(name="totalSoldItems", type=Integer.class), 
       @ColumnResult(name="totalSoldAmount", type=Double.class), 
       @ColumnResult(name="remItems", type=Integer.class), 
       @ColumnResult(name="loss", type=Double.class) 
      }) 
    } 
)

我不知道哪个版本JPA您正在使用2.0或2.1。 @ConstructorResult仅在JPA 2.1版本中受支持。检查您是否可以导入java.persistence.ConstructorResult而不会收到任何编译错误。

如果我需要指定实体，应该是什么表名？ –

在原生SQL查询中查询哪个表？这应该是将映射到您的实体类的表格。此外，您还没有真正使用您在createNativeQuery调用中声明的结果集映射。查看我发布的代码。 – Ish

我的结果集映射“LossDetailsMapping”是在上面提到的bean注释中定义的。我的本地SQL查询多个表 –
