我有以下问题：在我的数据库中有一个使用定义类型的表：
CREATE OR REPLACE TYPE ARRAY_METHODS IS VARRAY (10) OF NUMBER (2);
此列List<BigDecimal>在其各自的实体中映射。当我尝试使用 JPA 进行插入时，问题就开始了（我同时尝试了persist()和merge()）。寻找解决方案我发现我必须添加@Array和@Struct注释：
@Entity
@Struct(name="ARRAY_METHODS")
@Table(name="MY_TABLE")
...
@Array(databaseType="ARRAY_METHODS")
@Column(name="METHODS")
private List<BigDecimal> methods;
但它仍然失败：
