mybatisplus 自增主键失效，自增主键超大

问题现象

1.建表语句中设置id为自增id

create table aaa
(
    id                   bigint unsigned auto_increment comment '自增id'
        primary key,
   	type                 int          default 0                 not null comment '1.全部满足 2.任一满足',
    create_time          timestamp    default CURRENT_TIMESTAMP not null comment '创建时间',
    update_time          timestamp    default CURRENT_TIMESTAMP not null on update CURRENT_TIMESTAMP comment '更新时间'
