[java]  view plain  copy

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

mapper.xml的配置:

[html]  view plain  copy

1. <insert id="batchDelete">  
2.      delete from T_ACT_USERS where ACTIVITY_ID = #{activityId}  
3.      and USER_ID in  
4.      <foreach collection="userIds" item="item" index="index" open="(" separator="," close=")">  
5.             #{item}  
6.      </foreach>  
7. </insert>
