时间:2021-05-26

核心代码:

<%@ page contentType="text/html" pageEncoding="GB2312" language="java"%><%@ page import="java.sql.*"%><html> <head> <title>hello</title> </head> <body> <table border="1" spacing="2"><%! public static final String DRIVER = "com.mysql.jdbc.Driver"; public static final String USER = "root"; public static final String PASS = ""; public static final String URL = "jdbc:mysql://localhost:3306/teachinfo"; public static final int PAGESIZE = 5; int pageCount; int curPage = 1;%><% //一页放5个 String user = null; String pass = null; try{ Class.forName(DRIVER); Connection con = DriverManager.getConnection(URL,USER,PASS); String sql = "SELECT * FROM department"; PreparedStatement stat = con.prepareStatement(sql,ResultSet.TYPE_FORWARD_ONLY,ResultSet.CONCUR_READ_ONLY); ResultSet rs = stat.executeQuery(); rs.last(); int size = rs.getRow(); pageCount = (size%PAGESIZE==0)?(size/PAGESIZE):(size/PAGESIZE+1); String tmp = request.getParameter("curPage"); if(tmp==null){ tmp="1"; } curPage = Integer.parseInt(tmp); if(curPage>=pageCount) curPage = pageCount; boolean flag = rs.absolute((curPage-1)*PAGESIZE+1); out.println(curPage);//输出到屏幕上 int count = 0; do{ if(count>=PAGESIZE)break; int departmentid = rs.getInt(1); String departmentname = rs.getString(2); count++; %> <tr> <td><%=departmentid%></td> <td><%=departmentname%></td> </tr> <% }while(rs.next()); con.close(); } catch(Exception e){ }%></table><a href = "fenye.jsp?curPage=1" >首页</a><a href = "fenye.jsp?curPage=<%=curPage-1%>" >上一页</a><a href = "fenye.jsp?curPage=<%=curPage+1%>" >下一页</a><a href = "fenye.jsp?curPage=<%=pageCount%>" >尾页</a>第<%=curPage%>页/共<%=pageCount%>页</body></html>
