velocity，springmvc，springjdbc数据显示分页

第一次使用velocity模板，springjdbc的jdbcTemplate.queryForList获取的list是List<Map<String, Object>>类型，而不是常用的List<Object>类型，简单的写了一下数据显示以及分页。

 

velocity分页简单代码： 

 #foreach($ele in $pageBean)
            <tr #if($foreach.index%2==0) class="even" #else class="odd" #end>    
                #foreach($param in ${ele.keySet()})    
                <td>
                    #if(${ele.get($param)})
                        ${ele.get($param)}
                    #end
                </td>    
                #end   
            </tr> 
        #end 
</table>     																								共$!allRow条记录																							#if($allpage>1)

    共$!allpage页
    #set($prepage=$page - 1)
    #set($nextpage=$page + 1)

 

    <a href="$contextPath/data/list.do?cunId=$lastcun.cunId&page=1"><span>第一页</span></a>
    #if($page <= 1 )   
        <span>上一页</span>
    #else
        <a href="$contextPath/data/list.do?cunId=$lastcun.cunId&page=$prepage"><span> 上一页 </span></a>
    #end

    第$!page页

    #if($page >= $allpage )  
        <span>下一页</span>
    #else
        <a href="$contextPath/data/list.do?cunId=$lastcun.cunId&page=$nextpage"><span>下一页</span></a>
    #end
    <a href="$contextPath/data/list.do?cunId=$lastcun.cunId&page=$allpage"><span>最后一页</span></a>


#end

 

 

springmvc部分代码：

int pageSize= 10;
  
  String page = request.getParameter("page");
  int pageInt = 1;
  if (page != null) {
  pageInt = Integer.parseInt(page);
  if(pageInt <1)
  pageInt = 1 ;
  }

  // 获取数据
  List pageBean = dataService.getRowsOfCun(cunId ,pageInt ,pageSize);
  int allRow = dataService.getRowCountOfCun(cunId);
  int allpage = (allRow % pageSize == 0) ? (allRow / pageSize) : (allRow
  / pageSize + 1);


  mv.addObject("pageBean", pageBean);
  mv.addObject("page", pageInt);
  mv.addObject("allRow", allRow);
  mv.addObject("allpage", allpage);

springjdbc部分代码

 

public List getRowsOfCun(final String cunId)
 {
  List<Map<String, Object>> rows = jt
    .queryForList(
      "select name  from data where cunId=?",
      new Object[] {cunId});

  return rows;
 }






public List getRowsOfCun(String cunId, int pageInt, int pageSize) {
  
  if(getRowsOfCun(cunId).size()==0)
  {
  return null; 
  }
  List<Map<String, Object>> rows = jt
    .queryForList(
      //mysql版本
     /**
       "select name from data where cunId=? limit ?,?;",
      new Object[] {cunId,(pageInt * pageSize - pageSize),pageSize});
     */
      //ms sql版本
      "select  TOP (?) name from data where  (id NOT IN (SELECT TOP (?) id from data where cunId = ? ORDER BY id) ) and cunId = ?  ORDER BY ID",
      
      
    new Object[] {pageSize,(pageInt * pageSize - pageSize),cunId,cunId});
    
  
  return rows;
 }
