mybaties批量模糊查询、foreachstring[]用法

database

List<Recipe> randomRecipe(@Param("str")String[] strs,@Param("num")int num);

功能:随机查询num个不含strs[]的的Recipe

注:str:["苹果","甘蓝"]   num:5

<select id="randomRecipe" resultType="cn.jwm.onMK.po.Recipe">

select* from recipestable

<where>

mainmaterialname not like

<foreach item="str" index="index" collection="str" open="(" separator="AND" close=")">

CONCAT("%",#{str},"%")

</foreach>

</where>

order by rand()

limit #{num}

</select>

 

DEBUG [http-nio-8080-exec-3] - ==>  Preparing: select* from recipestable WHERE mainmaterialname not like ( CONCAT("%",?,"%") AND CONCAT("%",?,"%")) order by rand() limit ?
DEBUG [http-nio-8080-exec-3] - ==> Parameters: 甘蓝(String), 苹果(String), 5(Integer)

结合log输出    注意(   )的含义 和 and 用法
