mapper接口的方法：

public void batchDelete(@Param(value = "activityId") Integer activityId, @Param(value = "userIds") Integer[] userIds);

mapper.xml的配置:

<insert id="batchDelete">
        delete from T_ACT_USERS where ACTIVITY_ID = #{activityId}
        and USER_ID in
        <foreach collection="userIds" item="item" index="index" open="("
            separator="," close=")">
            #{item}
        </foreach>
 </insert>
