mybatis一些实现总结

1.获取一段时间内，每天的接口总调用量，5分钟平均调用量
<select id="queryRangeTimeAvgCount" parameterType="Map" resultMap="rangeTimeDayAvg">
    <![CDATA[
      SELECT day_num, MAX(totalCount) AS max_count, SUM(totalCount) AS total_count, AVG(totalCount) AS avg_count
        FROM
             (SELECT count_index, day_num, SUM(count) AS totalCount
                FROM api_counter
               WHERE day_num >= ${startDayNum} AND day_num < ${endDayNum}
    ]]>
    <if test="methodId != null">AND method_id = #{methodId}</if>
    <![CDATA[
    GROUP BY day_num, count_index) AS result
    GROUP BY day_num DESC
    ]]>
</select>

2.

<!--查看每个接口某一天的调用详情 按sum降序排序-->
<select id="getOverviewOneDay" parameterType="int" resultMap="apiOverviewResponse">
    <![CDATA[
    SELECT api_o.method_id,api_m.name,api_m.version,api_m.description,api_o.sum,api_o.day_num,api_o.status
     FROM api_overview api_o LEFT JOIN api_method api_m ON api_m.id =api_o.method_id
     WHERE day_num =#{dayNum} ORDER BY sum DESC;
    ]]>
</select>

3.

<!--分页查看每个接口某一天的调用详情 按sum降序排序-->
<select id="queryPaging" parameterType="java.util.Map" resultMap="apiOverview">
    <![CDATA[
    SELECT api_o.method_id,api_m.name,api_m.version,api_m.description,api_o.sum,api_o.day_num,api_o.status
     FROM api_overview api_o LEFT JOIN api_method api_m ON api_m.id =api_o.method_id
     WHERE day_num =#{searchParam.dayNum}
    ]]>
    <if test="searchParam.methodId != null">
        AND api_o.method_id = #{searchParam.methodId}
    </if>
    <if test="searchParam.methodName != null">
        AND api_m.`name` LIKE CONCAT('%','${searchParam.methodName}','%' )
    </if>
      <if test="searchParam.status != null">
        AND api_o.status = #{searchParam.status}
    </if>
    <![CDATA[
    ORDER BY ${sortRow} ${sortMethod} LIMIT ${offset}, ${pageSize};
    ]]>
</select>

4.分组之后再分页，接口平均调用时常

<select id = "queryPaging" parameterType="java.util.Map" resultMap= "statPerformance">
<![CDATA[
    SELECT id,method_id,name,version,description,avg_cost_time,avg_success_rate,count_index,day_num,create_time FROM (
    SELECT sp.id, sp.method_id,am.`name`,am.version, am.description,AVG(sp.cost_time) AS avg_cost_time,AVG(sp.rate) AS avg_success_rate, sp.count_index, sp.day_num,sp.create_time
    FROM api_method am,stat_performance sp 
    WHERE sp.method_id = am.id AND sp.day_num = #{searchParam.dayNum}
    ]]>
    <if test="searchParam.methodId != null">
        AND method_id = #{searchParam.methodId}
    </if>
    <if test="searchParam.methodName != null">
        AND am.`name` LIKE CONCAT('%','${searchParam.methodName}','%' )
    </if>
    <![CDATA[
    GROUP BY sp.method_id ORDER BY ${sortRow} ${sortMethod} ) a
    ]]>
     <if test="searchParam.startSpentTime != null and searchParam.endSpentTime != null">
        <![CDATA[ WHERE avg_cost_time >= #{searchParam.startSpentTime} AND avg_cost_time <= #{searchParam.endSpentTime}]]>
     </if>
     <![CDATA[
     LIMIT ${offset}, ${pageSize};
     ]]>
    
</select>
