Java SequenceGenerator与另一个数据库的自定义查询

Im使用SequenceGenerator和GeneratedValue以及序列“seq_user_hierarchy”在ID字段中执行“select nextval（'NAME_OF_sequence'）”

是否可以使用自定义查询（如“从\u视图的名称\u中选择值”）而不是默认查询

是否有其他方法在id字段中插入自定义查询的结果

提前谢谢

@Temporal(TemporalType.TIMESTAMP)

请尝试以下代码更改并确认其是否有效

public class UserHierarchy extends AuditableEntity {

...

@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "author_generator")
@SequenceGenerator(name="author_generator", sequenceName = "author_seq")
@Column(name = "id", updatable = false, nullable = false)
private Long id;

...

}

对上述代码段的解释：

在@GeneratedValue注释中，generator属性是在以下注释中定义的逻辑名称

在@SequenceGenerator注释中，sequenceName属性是数据库序列的实际名称，name属性是对上述生成器逻辑名称的解析

此外，这些链接（）可能对您有所帮助。

也许这可以帮助您。谢谢Varum，对不起，我不明白这将如何让我执行“从视图名称中选择值”并将其插入ID字段。为此，我相信您可以按照Roni Koren Kurtberg在您的查询评论中共享的链接进行操作。所以，这将允许您访问代码部分，您可以在其中选择下一个值以及其他内容。
