mybatis多参数传递(其中包括数组)

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>
