我的實體類已經標註爲：

@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查詢是：

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 ," 
      + " sd_data.tot_act_rt as totalInAmount ," + " NVL(ssd_data.sold_qnt,0) as totalSoldItems ," 
      + " NVL(ssd_data.sold_act_rt,0) as totalSoldAmount," 
      + " sd_data.total_act_qnt-NVL(ssd_data.sold_qnt,0) as remItems," 
      + " sd_data.tot_act_rt-NVL(ssd_data.sold_act_rt,0) as loss" + " FROM" + " (SELECT sd.BILL_ID,"

      + " FROM stock_sold_details ssd" + " WHERE ssd.REVERSED_PCS NOT IN ('C')" 
      // + " --AND ssd.SOLD_DATE > '01-JUL-2015'" 
      + " GROUP BY ssd.BILL_ID," + " ssd.BILL_SRL_NO" + " ORDER BY ssd.BILL_ID," + " ssd.BILL_SRL_NO"

      + " order by sd_data.bill_id," + " sd_data.bill_srl_no"; 
Query query = entityManager.createNativeQuery(LIST_LOSS_PROFIT_DETAILS,LossDetails.class); 
List<LossDetails> lossDtls = query.getResultList();

任何人，你可以幫助我在這段代碼中犯了什麼錯誤？

你可以給你的豆嗎？ –

您的LossDetails類是否使用@Entity映射？ – Ish

有2種方式來映射結果集本地的SQL查詢類的 - 無論是通過@EntityResult和@ConstructorResult

@EntityResult 它可以檢索本地SQL查詢管理的實體。您可以將通過SQL查詢返回的值映射到實體屬性。例如，您有一個實體類LossDetails.class並映射到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; 
}

然後，例如，您的本機SQL查詢將返回ff。列：

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

請注意，該列名不完全匹配您的實體類LossDetails的屬性名稱。對於這一點，你需要指定@SqlResultSetMapping這樣的：

@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列和實體的屬性完全一致的名稱相匹配，那麼你就需要枚舉的字段。就像這樣：

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

注意，有可能是原生SQL查詢從另一個表（從映射到實體表不同）選擇，只要所產生的列將被映射到每一個實體的屬性及其類型是兼容的。

要在創建本機查詢時使用聲明的結果集映射，只需通過名稱引用它即可。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

如果你的目的僅僅是你的本地SQL的結果映射到一個POJO或bean類，而豆不一定要通過對其進行保存/更新/刪除操作進行管理，那麼您不需要實體類。您實際上可以將SQL結果集列映射到純Java對象。我相信這是你想要使用的。使用JPA 2.1版本，您可以通過@ConstructorResult從本機查詢構建非實體類型。

下面是一個例子：

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只是一個POJO，而不是與@Entity註解。還要注意構造函數的存在。使用@ConstructorResult的sql結果集映射將使用此構造函數從本機SQL查詢結果中創建POJO。

每JPA規範：

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.

所以這裏有一個樣品使用的@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) 
      }) 
    } 
)

我不知道哪個版本JPA您正在使用2.0或2.1。 @ConstructorResult僅在JPA 2.1版本中受支持。檢查您是否可以導入java.persistence.ConstructorResult而不會收到任何編譯錯誤。

如果我需要指定實體，應該是什麼表名？ –

在原生SQL查詢中查詢哪個表？這應該是將映射到您的實體類的表格。此外，您還沒有真正使用您在createNativeQuery調用中聲明的結果集映射。查看我發佈的代碼。 – Ish

我的結果集映射「LossDetailsMapping」是在上面提到的bean註釋中定義的。我的本地SQL查詢多個表 –
