我想使用@JoinColumns从不同的表中获取数据-如何创建一个可以传递参数的条件？

@Entity
public class Order {
    // ...

    @ManyToOne
    @JoinColumns({
        @JoinColumn(name="customer_id", referencedColumnName="id"),
        @JoinColumn(name="product_id", referencedColumnName="id")
    })
    public Customer customer;
    // ...
}

// ...

EntityManager em = // 获取EntityManager实例

// 创建查询，传入参数的条件
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Order> query = cb.createQuery(Order.class);
Root<Order> order = query.from(Order.class);
ParameterExpression<Long> customerIdParam = cb.parameter(Long.class);
ParameterExpression<Long> productIdParam = cb.parameter(Long.class);
query.select(order).where(
    cb.equal(order.get("customer").get("id"), customerIdParam),
    cb.equal(order.get("product").get("id"), productIdParam)
);

// 执行查询
TypedQuery<Order> typedQuery = em.createQuery(query);
typedQuery.setParameter(customerIdParam, 123); // 设置customerId参数的值
typedQuery.setParameter(productIdParam, 456); // 设置productId参数的值
List<Order> results = typedQuery.getResultList();
