Question

我将Spring Data JPA从1.9.2升级到1.10.3后遇到了问题。

我有以下存储库：

public interface ShipmentStatisticRepository extends JpaRepository<Shipment, Long> {

    ...

    @Query("select new de.l.b.model.dto.shipment.ShipmentStatistic(s.createdYmd, count(distinct s.oid), count(op), sum(op.price)) " +
            "from Shipment s " +
            "join s.orderPosition op " +
            "where s.created between ?1 and ?2 " +
            "group by s.createdYmd")
    List<ShipmentStatistic> findPerDayBetweenCreated(Date from, Date to);

    ...
}

当我调用此方法时，我得到以下异常：

 org.springframework.dao.InvalidDataAccessApiUsageException: Could not instantiate Collection type: org.apache.openjpa.kernel.DelegatingResultList; nested exception is java.lang.IllegalArgumentException: Could not instantiate Collection type: org.apache.openjpa.kernel.DelegatingResultList

看起来存储库无法解析正确的构造函数来填充我的投影。使用1.9.2版本，一切正常。

这是我的投影课：

public class ShipmentStatistic implements Serializable {

    private Date date;
    private long totalParcelsSent;
    private long totalPositionsSent;
    private long totalValue;

    public ShipmentStatistic(Date date) {
        this.date = date;
        this.totalPositionsSent = 0;
        this.totalParcelsSent = 0;
        this.totalValue = 0;
    }

    public ShipmentStatistic(Date date, long totalParcelsSent, long totalPositionsSent, long totalValue) {
        this.date = date;
        this.totalPositionsSent = totalPositionsSent;
        this.totalParcelsSent = totalParcelsSent;
        this.totalValue = totalValue;
    }

    public ShipmentStatistic add(ShipmentStatistic other) {
        this.totalPositionsSent += other.totalPositionsSent;
        this.totalParcelsSent += other.totalParcelsSent;
        this.totalValue += other.totalValue;

        return this;
    }

    // getter and setter
}

我随机拍摄并尝试添加默认构造函数，但没有成功。

我无法看到我的错误，尤其是所做的唯一更改是框架更新。顺便说一下，我们使用OpenJPA 2.2.2作为Persistence API。我升级到当前版本2.4.1，但这也没有效果。

有什么建议吗？这可能是Spring Data JPA与OpenJPA结合的错误吗？

从stacktrace开始，看起来openjpa正在搜索默认构造函数。您可以尝试在 ShipmentStatistic.java ？

中明确添加默认构造函数

JPA规范要求使用默认的无参数构造函数。 http://openjpa.apache.org/builds/1.2.3/apache-openjpa/docs/jpa_overview_pc.html#jpa_overview_pc_no_arg

NoSuchMethodException with＆＃34; select new＆＃34;升级到Spring Data JPA 1.10.3之后
