mybatis插入数据返回id的实现方式

一、 useGeneratedKeys="true"

insert into user(id,username,birthday,sex,address) values (#{id},#{username},#{birthday},#{sex},#{address})

二、通过标签

select last_insert_id();

insert into user(id,username,birthday,sex,address) values (#{id},#{username},#{birthday},#{sex},#{address})
