Mybatis如何使用正则模糊匹配多个数据

select * from table where name REGEXP 'a|b|c'

<select id="selectAll" resultMap="BaseResultMap" parameterType="java.util.List">
    select *
    from student
    where name REGEXP
    <foreach collection="list" item="item" open="'" close="'" separator="|">
            #{item}
    </foreach>
</select>

select * from student where name REGEXP ' ? | ? | ? '

select * from student where name REGEXP ?

select * from student where name REGEXP CONCAT_WS('|',?,?,?)

<select id="selectAll" resultMap="BaseResultMap" parameterType="java.util.List">
    select *
    from student
    where name REGEXP CONCAT_WS('|',
    <foreach collection="list" item="item" open="" close="" separator=",">
        #{item}
    </foreach>
    )
</select>

    List<Map<String, Object>> findByMap(Map<String, Object>map);
    List<Map<String, Object>> findByMap2(Map<String, Object>map);

  <select id="findByMap" resultType="java.util.Map">
        SELECT id,pid as pIDDD,city_name,type FROM city
        WHERE 1=1
        <if test="keyWord != null and keyWord != ''">
            AND pid LIKE concat('%',#{keyWord},'%')
            OR city_name LIKE concat('%',#{keyWord},'%')
            OR type LIKE concat('%',#{keyWord},'%')
        </if>
    </select>

    <select id="findByMap2" resultType="java.util.Map">
        SELECT id,pid as pIDDD,city_name,type FROM city
        WHERE 1=1
        <if test="keyWord != null and keyWord != ''">
            AND CONCAT(IFNULL(pid,''),IFNULL(city_name,''),IFNULL(type,'')) LIKE concat('%',#{keyWord},'%')
