mybaties批量删除

mapper .java文件

void deleteByActivityIds(@Param("ids") String[] ids);

mapper.xml文件

        <result column="creditcard_id" property="creditcardId" jdbcType="INTEGER"/>

 <delete id="deleteByActivityIds">
        DELETE FROM credit_creditcard_activity_ref
        WHERE creditcard_id IN
        <foreach collection="ids" item="id" open="(" separator="," close=")">
            #{id}
        </foreach>
    </delete>

注意传过去的参数是String[] 类型的 但是id确实integer类型的

照样通过
