我正在使用Spring+，Hibernate并且在特殊情况下，Entity由于查询，我需要获取（列表）非对象。

我决定使用@ConstructorResultin，@SqlResultSetMapping并在其中引用此映射@NamedNativeQuery，如此处和此处所述。

但是，在所有使用命名本机查询的示例中，它们都EntityManager通过获取实例@PersistenceContext并对其进行调用createNativeQuery，从而为该调用提供nameof
@NamedNativeQuery参数，如该答案所示。

如何将存储库中声明的方法映射interface到特定对象@NamedNativeQuery？我的尝试是使用EntityName.MethodNameInRepository或MethodNameInRepository作为name的@NamedNativeQuery，但没有运气。

这是我的简化代码：

@Entity(name = "AdDailyData")
@SqlResultSetMapping(
        name="RevenueByAppAndDayMapping",
        classes=@ConstructorResult(
                targetClass=RevenueByAppAndDay.class,
                columns={@ColumnResult(name="country_code"),
                        @ColumnResult(name="revenue", type=Double.class),
                        @ColumnResult(name="currency")}))
@NamedNativeQuery(
        name="AdDailyData.aggregateRevenue",
        query="SELECT country_code, sum(earnings) as revenue, currency "
                + "FROM ad_daily_data, pseudo_app, app "
                + "WHERE ad_daily_data.pseudo_app_id=pseudo_app.id AND pseudo_app.app_id=app.id AND app.id=:appId and ad_daily_data.day = :day "
                + "GROUP BY country_code, currency "
                + "ORDER BY country_code ASC",
        resultSetMapping="RevenueByAppAndDayMapping")
public class AdDailyDataEntity {

    // fields, getters, setters etc.

    public static interface Repository extends JpaRepository<AdDailyDataEntity, Long> {

        public List<RevenueByAppAndDay> aggregateRevenue(@Param("appId") long appId, @Param("day") LocalDate day);

    }

}

这是我的非Entity班级。

public class RevenueByAppAndDay {

    private String countryCode;
    private Double earnings;
    private String currency;

    public RevenueByAppAndDay(String countryCode, Double earnings, String currency) {
        this.countryCode = countryCode;
        this.earnings = earnings;
        this.currency = currency;
    }

    public String getCountryCode() {
        return countryCode;
    }

    public Double getEarnings() {
        return earnings;
    }

    public String getCurrency() {
        return currency;
    }

}

任何帮助都将受到高度赞赏。
