java分页 Struts+Ibatis

首先写一个分页类：

1. package com.zc.book.util;  
2.   
3. import java.util.List;  
4.   
5. public class PageUtil {  
6.   
7.      private int pageSize=20;//每页显示的条数 默认20  
8.        
9.      private int recordCount;//记录总数  
10.        
11.      private int currentPage;//当前页  
12.        
13.      private int pageIndex;//每页的第一条记录编号  
14.        
15.      private List pageList;//每页的记录集  
16.        
17.      private int totalPage;//总页数  
18.   
19.     public int getPageSize() {  
20.         return pageSize;  
21.     }  
22.   
23.     public void setPageSize(int pageSize) {  
24.         this.pageSize = pageSize;  
25.     }  
26.   
27.     public int getRecordCount() {  
28.         return recordCount;  
29.     }  
30.   
31.     public void setRecordCount(int recordCount) {  
32.         this.recordCount = recordCount;  
33.     }  
34.   
35.     public int getCurrentPage() {  
36.         return currentPage;  
37.     }  
38.   
39.     public void setCurrentPage(int currentPage) {  
40.         this.currentPage = currentPage;  
41.     }  
42.   
43.     public int getPageIndex() {  
44.         return pageIndex;  
45.     }  
46.   
47.     public void setPageIndex(int pageIndex) {  
48.         this.pageIndex = pageIndex;  
49.     }  
50.   
51.     public List getPageList() {  
52.         return pageList;  
53.     }  
54.   
55.     public void setPageList(List pageList) {  
56.         this.pageList = pageList;  
57.     }  
58.   
59.     public int getTotalPage() {  
60.         return totalPage;  
61.     }  
62.   
63.     public void setTotalPage(int totalPage) {  
64.         this.totalPage = totalPage;  
65.     }  
66.       
67.     //初始化 currentPage 当前页,pageSize 每页大小,recordCount 总记录数,pageIndex 每页第一条记录序号  
68.     public void init(int currentPage,int pageSize,int recordCount){  
69.         this.currentPage=currentPage>0?currentPage:1;//设置当前页  
70.         this.pageSize=pageSize;//设置每页大小  
71.         this.recordCount=recordCount;//设置总记录数  
72.         this.pageIndex=(currentPage-1)*pageSize;//设置每页第一条记录  
73.         this.totalPage=recordCount/pageSize+1;  
74.         if(currentPage>totalPage){  
75.             currentPage=totalPage;  
76.         }  
77.     }  
78. }  

在Action中

1. int currentPage = 1;  
2.           
3.         try {  
4.             currentPage = Integer.parseInt(request.getParameter("currentPage"));  
5.         } catch(Exception ex) {  
6.         }  
7.           
8.         PageUtil pageUtil=new PageUtil();  
9.           
10.         pageUtil=bookService.pageBookInfo(currentPage);  
11.         request.setAttribute("pageUtil", pageUtil);  
12.   
13.         return mapping.findForward("bookInfo");  

service中的pageBookInfo方法：

 

1. public PageUtil pageBookInfo(int currentPage) {  
2.         // TODO Auto-generated method stub  
3.         List list=bookDao.bookInfo();  
4.           
5.         PageUtil pageUtil=new PageUtil();  
6.           
7.         //设置当前页，每页记录数，总记录数  
8.         pageUtil.init(currentPage, 25, list.size());  
9.           
10.         //通过pageUtil的"pageIndex--每页的第一条记录编号"和"pageSize--每页显示的条数"  
11.         //这两个参数去数据库中查询出其中一页的记录，放入List里  
12.         list=bookDao.pageBook(pageUtil);  
13.           
14.         //将list中一页的记录放入pageUtil  
15.         pageUtil.setPageList(list);  
16.           
17.         return pageUtil;  
18.     }  

sqlMap中的语句：

1.   
2.     select * from bookinfo  
3.   
4.   
5.   
6.     select * from bookinfo limit #pageIndex#,#pageSize#  
7.   

在jsp中添加：

1.   
2.             
3.             共${pageUtil.recordCount }条纪录，当前第${pageUtil.currentPage }/${pageUtil.totalPage }页，每页${pageUtil.pageSize }条纪录  
4.               
5.                 
6.                   
7.              
8.                   

  

                  

  

                    

             

             

                  book.do?method=page¤tPage=1" target='I1'>  

                  book.do?method=page¤tPage=${pageUtil.currentPage-1 }" target='I1'>  

             

             

                    

                    

             

             

                  book.do?method=page¤tPage=${pageUtil.currentPage+1 }" target='I1'>  

                  book.do?method=page¤tPage=${pageUtil.totalPage }" target='I1'>  

             

                  转到第
