从数据库查出一个list,显示在JSP页面上,如何加序号?

根据当前页的序号，做 *** 作

规律是：listsize：每页总条数， ipage：当前页数，

起始：listsize *（ipage-1） + 1

再去循环 listsize次循环 i++

切记： 保证 ipage，listsize 都 >= 1

具体JSP语法，不会。。。，但思路是一样的

<%@ page import="java.text.*" %>

<%

String time = ""

SimpleDateFormat dformat = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss")

time = dformat.format(new java.util.Date())

time = time.replaceAll("-","")

time = time.replaceAll(" ","")

time = time.substring(0,4)

String ReportType=request.getParameter("ReportType")

Statement stmt = null

ResultSet rs = null

Connection conn = null

SQLBean_JDBC so = new SQLBean_JDBC()

String stringSql=""

String serial4=""

stringSql = "select max(convert(int,substring(yewubaogaodanhao,9,4)))+1 as yewubaogaodanhao "

+" from tuoyun where substring(yewubaogaodanhao,1,4)='"+time+"'"

String serial= ""

try{

conn = so.getConnection()

stmt = conn.createStatement()

rs = stmt.executeQuery(stringSql)

}

catch (Exception ex) {

System.out.println("nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn")

}

while (rs.next()){

try {

serial4 = rs.getString("yewubaogaodanhao")

%>

<%

} catch (Exception ex) {

System.out.println("qqqqqqqqqqqqqqqqqqqqqqqqqqq"

+ ex.getMessage())

%>

<%

}

}

rs.close()

stmt.close()

conn.close()

if(serial4==null){serial4="0001"}

if(serial4.length()==1){serial4="000"+serial4}

if(serial4.length()==2){serial4="00"+serial4}

if(serial4.length()==3){serial4="0"+serial4}

serial = time+"RLMD"+serial4

%>
