我的hibernate配置设置
<id name="ID" type="java.lang.Long">
<column name="ID" />
<generator class="native" />
</id>
数据库字段设置
"ID" BIGINT NOT NULL GENERATED BY DEFAULT
AS IDENTITY (START WITH 1, INCREMENT BY 1, CACHE 20,
NO MINVALUE, NO MAXVALUE, NO CYCLE, NO ORDER),
java端设置
private Long taskid;
这样自增长的id，然后入库没有问题，但是有时候会出现无法生成id的情况，请帮忙看下
