Question

@TableGenerator(name = "ParticipantGen", schema = "sa", table = "ADP_TBL_OID", pkColumnName = "TYPE_ID", pkColumnValue = "5321", valueColumnName = "OBJ_NUM", allocationSize = 50)
@Id
@GeneratedValue(strategy = GenerationType.TABLE, generator = "ParticipantGen")
    private BigInteger objid;

我有一个像上面这样的配置来生成表的主键。密钥的下一个值是负数。当我运行流程时，不知何故，JPA不接受-ve数字并在无限循环中运行以获得正数。因此，应用程序阻塞，因为未释放插入表记录的db线程。

如果有人可以在这里提供帮助，那会很棒。

OPEN JPA - @TableGenerator，其中负值在infinate循环中运行
