Mybatis如何获取最新插入数据的id

SELECT * FROM admin_users where 1=1 ORDER BY id desc  LIMIT 1
select MAX(id) from admin_users

<!--表名-->
    <sql id="tableName">IMS_BS_BOOK_COPY</sql>
    <!--字段-->
    <sql id="insertField">PRICE,ENTITY_ID,CODE,ADD_TIME,STATUS,REASON,GRID_CODE,STALL_CODE,CASE_CODE,ORDER_CODE</sql>
    <!--字段值-->
    <sql id="insertFieldValue">#{PRICE},#{ENTITY_ID},#{CODE},#{ADD_TIME},#{STATUS},#{REASON},#{GRID_CODE},#{STALL_CODE},#{CASE_CODE},#{ORDER_CODE}</sql>
    <!--新增-->
    <insert id="save" parameterType="pd" useGeneratedKeys="true" keyProperty="id">insert into
        <include refid="tableName"/>(
        <include refid="insertField"/>) values (
        <include refid="insertFieldValue"/>)
    </insert>

<select id="selectLast" resultMap="BaseResultMap" parameterType="java.lang.String">
        SELECT
        *
        from 表名
        where createtime=(select max(createtime) from 表名 where
        字段名=#{参数名,jdbcType=VARCHAR} )
    </select>

select id="selectLast" resultMap="BaseResultMap" parameterType="java.lang.String">
            select t.*,rownum from
            (select * from 表名  where  字段名=#{参数名,jdbcType=VARCHAR} 
            order by createtime desc)t   where rownum=1
    </select>
