若是直接

SELECT * FROM project_celiangbuwei where clbwid in ( 7 , 11 , 20 , 4 ) 

则输出结果为:

4 净胸围
7 净臀围
11 肩宽
20 横裆

使用Field函数排序后:

SQL:

SELECT * FROM project_celiangbuwei where clbwid in ( 7 , 11 , 20 , 4 )  ORDER BY FIELD(clbwid,7,11,20,4)

输出结果:

7 净臀围
11 肩宽
20 横裆
4 净胸围


mybatis 设置:

<select id="findByIds"  resultType="com.bwhx.eruler.bean.CeliangBuwei">SELECT *   FROM project_celiangbuwei where clbwid in <foreach collection="array" index="index" item="item" open="(" separator=","  close=")" >    #{item}    </foreach>   order by   field(  clbwid,  <foreach collection="array" index="index" item="item"   separator=","    >    #{item}    </foreach>   )</select>
