jsp+mysql+XPAGERv2.0实现分页！

1.将XPAGERv2.0的源码或jar包导入项目。

2.将page.tld拷入您的WEB-INF下。
3.在web.xml添加：
   
        /xdevelop.net/taglibs/page
        /WEB-INF/page.tld
   

4.jsp中：

<%@ taglib uri="/xdevelop.net/taglibs/page" prefix="page"%>
<%@ page import="net.xdevelop.util.*"%>

<%

WebApplicationContext wac = WebApplicationContextUtils
     .getWebApplicationContext(config.getServletContext());
   IUserService ius = (IUserService) wac.getBean("userService");
   int totalRecords = ius.queryQdListCount(sessinUserID, qsrq, jzrq);//取得满足条件的所有记录数

   %>
把放在数据列表

的外层。

核心代码如下：

  

 

  
   
  
  
  
  
  
  
  
  
  
  
  
  
  
  <%KqListVO kqListVO = null;
    String fontColor = "#000000";
    List userOneDayList = ius.queryQdList(sessinUserID, qsrq, jzrq,
      index.intValue(), pageSize.intValue());//取得指定页的记录集
    String rowgrcolor = "";
    int rowjo = 0;
    for (Iterator iter = userOneDayList.iterator(); iter.hasNext();) {
     kqListVO = (KqListVO) iter.next();
     if (kqListVO.getQdtime().compareTo("") == 0
       || kqListVO.getQttime().compareTo("") == 0) {
      fontColor = "#FF0000";
     } else {
      fontColor = "#000000";
     }
     if (rowjo % 2 == 0) {
      rowgrcolor = "#FFFFFF";
     } else {
      rowgrcolor = "#E8E8E8";
     }

     %>
  

   onMouseOut="hideMsg();" style="cursor:hand">
   
   
   
   
   
   
   
   
   
   
   
  
  <%rowjo++;
    }%>
