mybatis插入数据返回id的实现方式

一、 useGeneratedKeys="true"

  <insert id="saveUser" parameterType="com.apcstudy.user.domain.User"
        useGeneratedKeys="true" keyProperty="id" keyColumn="id">
    insert into user(id,username,birthday,sex,address) values (#{id},#{username},#{birthday},#{sex},#{address})
  </insert>

二、通过标签

<insert id="saveUser2" parameterType="com.apcstudy.user.domain.User">
    <selectKey keyProperty="id" keyColumn="id" resultType="integer" order="AFTER">
        select last_insert_id();
    </selectKey>
    insert into user(id,username,birthday,sex,address) values (#{id},#{username},#{birthday},#{sex},#{address})
</insert>
