mybatis中if标签用法

1         <if test="grouptype != null ">
2             <if test="grouptype == 0">
3                 and i.ent_id not in (select id from group_type)
4             </if>
5             <if test="grouptype == 1">
6                 and i.ent_id in (select eid from group_type)
7             </if>
8         </if>

mapper传入参数为map，其中的int类型可以这样直接判断。
