　　myBatis 分页：
　　mybatis sql脚本：
　　<select id="getAllHnbPage" resultType="hashmap" parameterType="pageInfo">
  <![CDATA[
      select * from view_HNBIdentifier order by hnbIdentifier asc limit #{startNum}, #{pageSize}
     ]]>
 </select>
　　<select id="getAllHnbCount" resultType="int">
  <![CDATA[
      select count(*) from view_HNBIdentifier
     ]]>

　　DAO方法：
　　public List<HashMap<String, Object>> getAllHnbPage(PageInfo page);
　　serviceImpl：
　　

 public List<HnbInfo> getHnbListPage(PageInfo page)

    {

        List<HnbInfo> hnbList = new ArrayList<HnbInfo>();

       

        // 获取所有的基站信息
