不好意思，应为我同事在用触发器+序列解决的原因，所以无法还原日志 ，但是主要错误是这个，

2，创建序列（实现主键自增的必要前提）
Java代码
--创建序列（实现person，address主键自增的必要序列）
create sequence seq_nutz
increment by 1
start with 1
maxvalue 999999999;
3，给要主键自增的表上创建触发器（在插入前利用触发器给主键id赋值）
Java代码
--给person表创建触发器--实现主键自增
CREATE TRIGGER trigger_pk_person BEFORE
insert ON T_PERSON FOR EACH ROW
begin
select seq_nutz.nextval into:New.id from dual;
end;
