升级到Spring Boot 3.0后,以下查询不再有效:

@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,
)

是否不再可能像使用op那样传递整个DB对象?

SUM在应用于整数类型的状态字段时返回LongBigInteger除外);Double,当应用于浮点类型的状态字段时;BigInteger,当应用于类型BigInteger的状态字段时;以及当应用于类型X1 M7 N1 X的状态字段时的X1 M6 N1 X。
这是来自JPA 3.1 specification的。
所以它应该返回一个Long。我怀疑它被你的数据类中的构造函数弄糊涂了。如果你把类型从Int改为Long并移除额外的构造函数会发生什么?

您的sql看起来有什么问题,请尝试更改为以下内容
升级到Sping Boot 3.0后,以下查询不再有效:

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

我没看到你有t表和p表联查@kaulex
