java中對list分頁并顯示數(shù)據(jù)到頁面實例代碼

這篇文章主要介紹了java中對list分頁并顯示數(shù)據(jù)到頁面實例代碼，分享了相關(guān)代碼示例，小編覺得還是挺不錯的，具有一定借鑒價值，需要的朋友可以參考下

有時候需要根據(jù)條件查詢得出的數(shù)據(jù)較多，需要分頁顯示到頁面上。這時點擊下一頁就不方便每次帶查詢條件在數(shù)據(jù)庫中分頁。可以在list中進(jìn)行分頁。

page的model類：

public class Page { 
  private Integer currentPage;//當(dāng)前頁 
  private int pageSize;//每頁顯示記錄條數(shù) 
  private int totalPage;//總頁數(shù) 
  private List<?> dataList;//每頁顯示的數(shù)據(jù) 
  private int star;//開始數(shù)據(jù) 
 
  public Integer getCurrentPage() { 
    return currentPage; 
  } 
  public void setCurrentPage(Integer currentPage) { 
    this.currentPage = currentPage; 
  } 
  public int getPageSize() { 
    return pageSize; 
  } 
  public void setPageSize(int pageSize) { 
    this.pageSize = pageSize; 
  } 
  public int getTotalPage() { 
    return totalPage; 
  } 
  public void setTotalPage(int totalPage) { 
    this.totalPage = totalPage; 
  } 
  public List<?> getDataList() { 
    return dataList; 
  } 
  public void setDataList(List<?> dataList) { 
    this.dataList = dataList; 
  } 
  public int getStar() { 
    return star; 
  } 
  public void setStar(int star) { 
    this.star = star; 
  } 
}

控制層：

@RequestMapping("fenye.do") 
  public String fen(Page page,HttpServletRequest request){ 
 
    try { 
      //查詢出的list數(shù)據(jù) 
      List<Data> showdata=loginService.selectyichall(); 
      //剛開始的頁面為第一頁 
      if (page.getCurrentPage() == null){ 
        page.setCurrentPage(1); 
      } else { 
        page.setCurrentPage(page.getCurrentPage()); 
      } 
      //設(shè)置每頁數(shù)據(jù)為十條 
      page.setPageSize(10); 
      //每頁的開始數(shù) 
      page.setStar((page.getCurrentPage() - 1) * page.getPageSize()); 
      //list的大小 
      int count = showdata.size(); 
      //設(shè)置總頁數(shù) 
      page.setTotalPage(count % 10 == 0 ? count / 10 : count / 10 + 1); 
      //對list進(jìn)行截取 
      page.setDataList(showdata.subList(page.getStar(),count-page.getStar()>page.getPageSize()?page.getStar()+page.getPageSize():count)); 
      //設(shè)置作用域 
      request.setAttribute("paging", page);         
      return "add/show.jsp"; 
 
    } catch (Exception e) { 
      // TODO Auto-generated catch block    
      e.printStackTrace(); 
      return "mistake.jsp"; 
    } 
  }

jsp頁面：

<script type="text/javascript" language="javascript"> 
 function goPage(page){ 
 location.href="fenye.do?currentPage=" rel="external nofollow" +page; 
 } 
</script> 
 
 
<div> 
 <table width="100%" border="0" align="center" cellspacing="1" > 
 <c:forEach items="${paging.dataList }" var="upl">    
   <tr> 
    <td align="center">${upl.name1 }</td> 
    <td align="center">${upl.name2 }</td> 
    <td align="center">${upl.name3 }</td>    
   </tr> 
   </c:forEach>   
 </table> 
</div> 
<div style="text-align:center; margin-top:10px;color: white;" id="venderfen"> 
 <c:if test="${paging.totalPage > 0}"> 
  當(dāng)前第 ${paging.currentPage } 頁/共  ${paging.totalPage} 頁 
 </c:if> 
 <c:if test="${paging.totalPage > 1}"> 
   <c:choose> 
     <c:when test="${paging.currentPage==2 && paging.totalPage==2}"> 
      <a onclick="goPage(1)">首頁</a> 
      <a onclick="goPage(${paging.currentPage-1})">上一頁</a> 
     </c:when> 
     <c:when test="${paging.currentPage==1}"> 
      <a onclick="goPage(${paging.currentPage+1})">下一頁</a> 
      <a onclick="goPage(${paging.totalPage})">末頁</a> 
     </c:when> 
     <c:when test="${paging.currentPage==paging.totalPage}"> 
      <a onclick="goPage(1)">首頁</a> 
      <a onclick="goPage(${paging.currentPage-1})">上一頁</a> 
     </c:when> 
     <c:otherwise> 
      <a onclick="goPage(1)">首頁</a> 
      <a onclick="goPage(${paging.currentPage-1})">上一頁</a> 
      <a onclick="goPage(${paging.currentPage+1})">下一頁</a> 
      <a onclick="goPage(${paging.totalPage})">末頁</a> 
     </c:otherwise> 
  </c:choose> 
  </c:if> 
 共 ${paging.total} 條 
</div>

StringBuilder sb = new StringBuilder(); 
sb.append("SELECT distinct(m.time) "); 
sb.append(" from tbl_monitor m left join tbl_variable v on m.variable = v.id "); 
sb.append(" left join tbl_variable_group g on v.variable_group = g.id "); 
       
sb.append(" where v.active = true and g.active=true "); 
//sb.append(" AND m.variable in " + variableIds); 
sb.append(" AND exists ( select vtemp.id from tbl_variable vtemp where vtemp.selected=true and vtemp.id=m.variable)"); 
sb.append(" AND m.time between " + beginTime + " AND " + endTime ); 
sb.append(" order by m.time asc"); 
Query query = em.createNativeQuery(sb.toString()); 
//滿足搜索條件的所有的時間的條數(shù) 
int total = query.getResultList().size(); 
tableView.setTotal(total); 
tableView.setTotalPage(total % page.getPageSize() == 0 ? total / page.getPageSize() : (total / page.getPageSize()) + 1); 
query.setFirstResult(from); 
query.setMaxResults(offset); 
timeList = query.getResultList();
