Solution to the Paging Error of mysql One to many Association Query

list is included in the query data in xml, and collection is required

<resultMap id="XX" type="com.XXX.XXXX">
    <id column="o_id" jdbcType="BIGINT" property="id" />
    <result column="o_user_id" jdbcType="BIGINT" property="userId" />
    ....
    <collection property="orderProductList" ofType="com.XXXXXX.XXXXX">
      <id column="p_id" jdbcType="BIGINT" property="id" />
      <result column="p_order_id" jdbcType="BIGINT" property="orderId" />
      ....
    </collection>
  </resultMap>

The general paging query encapsulated by such a query system is wrong, so it needs to be solved by adding paging in sql

<select id="XXX" resultMap="OrderListMap">
    SELECT
    you.nick_name,
    yo.id o_id,
    yo.user_id o_user_id
    FROM
    (
    SELECT * FROM
    youpin_order
    WHERE
    1 = 1
    <if test="status != null">
      and `status` = #{status}
    </if>
    <if test="page != null and limit != null">
    LIMIT #{page},
    #{limit}
    </if>
    ) yo
    LEFT JOIN XXX yop ON yo.id = yop.order_id
    LEFT JOIN XXXX you ON yo.user_id = you.id
  </select>

When passing in parameters, you need to calculate

(offset - 1) * limit, limit
