mysql - 使用 @SqlDelete 的 JPA 软删除会导致 SQL 错误 : Parameter index out of range (2 > number of parameters,，即 1)

Question

我有 Basket 和 BasketItem 实体，它们都扩展了 BaseEntity，如下所示:

@MappedSuperclass
public class BaseEntity {
    @Id @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "deleted", nullable = false)
    private Boolean deleted = false;

    @Version @Column(nullable = false)
    private Long version;
}

@Entity
@Where(clause = "deleted = false")
@SQLDelete(sql = "UPDATE basket SET deleted=true WHERE id=?")
public class Basket extends BaseEntity {
    @OneToMany(mappedBy = "basket", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.LAZY)
    private List<BasketItem> items = new ArrayList<>();
}

@Entity
@Where(clause = "deleted = false")
@SQLDelete(sql = "UPDATE basketItem SET deleted=true WHERE id=?")
public class BasketItem extends BaseEntity {
    @ManyToOne(optional = false)
    @JoinColumn(name = "basket_id", nullable = false)
    private Basket basket;
}

现在，当我想从 Basket 中删除 BasketItem 时，我只需在购物篮项目列表上调用 remove(basketItem) 并保存篮子实例:

@Service
public class DeleteBasketItemUseCase {

    @Transactional
    public BasketOutput execute(final Long itemId, final Long basketId) {
        // loading and checks omitted 
        basket.getItems().remove(basketItem);
        basket = basketRepository.save(basket);
    }
}

删除basketItem会生成MySQL错误:

java.sql.SQLException: Parameter index out of range (2 > number of parameters, which is 1)

日志中生成的SQL是:

UPDATE
        basketItem 
    SET
        deleted=true 
    WHERE
        id = ?

我正在使用

• Spring Boot 2.2.6.RELEASE
• MySQL 8.0
• Hibernate 5.4.12.Final
• mysql-connector-java-8.0.19

我更新@SQLDelete并在注释末尾添加和version=?:

@SQLDelete(sql = "UPDATE basket SET deleted=true WHERE id=? and version=?")
@SQLDelete(sql = "UPDATE basket_item SET deleted=true WHERE id=? and version=?")

注意:我还更改了数据库表名称!
