我有班级建设：

@JsonBackReference
@OneToMany(cascade = CascadeType.MERGE, orphanRemoval = true, fetch = FetchType.LAZY, mappedBy = "building")
private List<Floor> floorList = new ArrayList<>();

另一方面：

@JsonManagedReference
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "BUILDING_ID")
private Building building;

现在我根本无法删除建筑，当我尝试删除byid（id）时，出现了以下错误：

org.h2.jdbc.JdbcSQLIntegrityConstraintViolationException: Naruszenie więzów integralności: "FKNRVYGRFI0C51V0GF7JI9KF4QK: PUBLIC.ASSET FOREIGN KEY(FLOOR_ID) REFERENCES PUBLIC.FLOOR(ID) (129)"
Referential integrity constraint violation: "FKNRVYGRFI0C51V0GF7JI9KF4QK: PUBLIC.ASSET FOREIGN KEY(FLOOR_ID) REFERENCES PUBLIC.FLOOR(ID) (129)"; SQL statement:
delete from floor where id=? [23503-200]

我尝试过cascade=cascadetype.all、merge、remove和without cascade，但都没有效果。删除建筑的唯一方法是首先删除所有楼层（floorlist为空）。
