查询中带有 Jpa 3.1 实例化的 Spring Boot 3.0 不起作用

问题描述 投票：0回答：3

自从升级到 Spring Boot 3.0 后，以下查询不再起作用：

   @Query("""
        select new com.example.OrderProductWithAmount(
            op, sum(op.amount), sum(op.paidAmount)
        )
        from OrderProduct op
        join op.order o join op.product p join o.table t
        where t.id = :tableId group by p.id
        """)
    fun getAllSummarizedByTableId(@Param("tableId") tableId: Long): List<OrderProductWithAmount>

data class OrderProductWithAmount(
    val orderProduct: OrderProduct,
    val amount: Int,
    val paidAmount: Int
) {
    constructor(
        orderProduct: OrderProduct,
        amount: Long,
        paidAmount: Long
    ) : this(
        orderProduct,
        amount.toInt(),
        paidAmount.toInt()
    )
}

@Entity
@jakarta.persistence.Table(name = "order_product")
data class OrderProduct(
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    var id: Long = -1,

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "order_id", nullable = false)
    var order: Order,

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "product_id", nullable = false)
    var product: Product,

    @Column(name = "amount", nullable = false)
    var amount: Int,

    @Column(name = "paid_amount", nullable = false)
    var paidAmount: Int = 0,
)

是否不再可能像我使用 

op
那样传递整个数据库对象？

spring-boot jpa spring-data-jpa spring-data spring-kotlin

当应用于整数类型的状态字段（

SUM

除外）时，
Long
返回
BigInteger
； 
Double
应用于浮点类型的状态字段时； 
BigInteger
当应用于 
BigInteger
类型的状态字段时；和 
BigDecimal
当应用于 
BigDecimal
类型的状态字段时。

这来自 JPA 3.1 规范。

所以它应该返回一个

Long
。我怀疑它会被数据类中的构造函数混淆。如果将类型从 
Int
更改为 
Long
并删除附加构造函数，会发生什么？

你的sql看起来有问题，尝试更改为以下内容

自从升级到 Spring Boot 3.0 后，以下查询不再起作用：

  @Query("""
        select new com.example.OrderProductWithAmount(
            op, sum(op.amount), sum(op.paidAmount)
        )
        from OrderProduct op
        where op.id = :tableId group by op.id
        """)

我没有看到你有t表和p表关联查询 @kaulex

在我的例子中，我创建了一个具有三个默认参数（JPQL 查询中使用的参数）的构造函数，并将所有数字字段设置为 Long。
