ibatis查询条件包含IN

ibatis查询SQL中有时候需要用到IN条件，怎么使用呢？

如下，其中provinceIDStr和cityIDStr是在实体类里面定义的属性provinceID和cityID对应的数组；

private String[] provinceIDStr;        //所在省ID数组
private String[] cityIDStr;            //所在市ID数组

实现代码：

<select id="getList">
        SELECT * from user
        <dynamic prepend="WHERE">
            <isNotNull prepend="AND" property="id"> id=#id# </isNotNull>
            <isNotNull prepend="AND" property="userName"> userName like '%$userName$%' </isNotNull>
            <isNotNull prepend="AND" property="provinceID"> provinceID=#provinceID# </isNotNull>
            <isNotNull prepend="AND" property="cityID"> cityID=#cityID# </isNotNull>
            
            <isNotNull prepend="AND" property="provinceIDStr">
                 provinceID in
                 <iterate open="(" close=")" conjunction="," property="provinceIDStr" >  
                    #provinceIDStr[]#  
                </iterate> 
            </isNotNull>
            
            <isNotNull prepend="AND" property="cityIDStr">
                 cityID in
                 <iterate open="(" close=")" conjunction="," property="cityIDStr" >  
                    #cityIDStr[]#  
                </iterate> 
            </isNotNull>
            
        </dynamic>    
            order BY id ASC
    </select>
