Spring Boot 3.0与Jpa 3.1实例化查询不工作

Question

由于升级到Spring Boot 3.0以下查询不再工作:

@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,
)

是不可能再传递整个DB对象，就像我做它与op?

Answer 1

SUM应用于整型状态字段(BigInteger除外)时返回Long;Double应用于浮点类型的状态字段时;BigInteger当应用于类型为BigInteger的状态字段时;和BigDecimal，当应用于BigDecimal类型的状态字段时

来自JPA 3.1规范。

所以它应该返回Long。我怀疑它会被数据类中的构造函数所混淆。如果将类型从Int更改为Long并删除额外的构造函数，会发生什么情况?

Answer 2

您的sql出现问题，请尝试更改为以下

由于升级到Spring Boot 3.0以下查询不再工作:

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

我没有看到你有一个t表和p表相关联的查询@kaulex

Answer 3

在我的例子中，我创建了一个带有三个默认参数(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。
