其实关键就在于数据库的查询！我使用了三个select嵌套语句
<%//说明count是总的记录的条数
//page是用户提交的参数，用于控制分页的，允许的值是正整数，负整数
int i=count/15; //总页,每页显示15条记录
int j=i/10; //总的大页 ,没10个页面分一大页
//Page 显示的页面
int StartPage;
//int HrefPage;
if (Page<0) Page=0-Page*10; //10页分一次
StartPage=Page/10; //10页分一次
out.print ("[共有"+i+"页]");
//out.print ("共有"+j+"屏");
//out.print ("显示第"+Page+"页");
//out.print ("StartPage="+StartPage);
if (StartPage>0)
out.print ("|<a href=\"connectmysql.jsp?page=-"+Integer.toString(StartPage-1)+"\">前10页</a>");
for (int k=0;k<10;k++)
{ int p=StartPage*10+k;
if (p>i) break;
if (p==Page)
out.print ("|第"+Integer.toString(p+1)+"页");
else
out.print ("|<a href=\"connectmysql.jsp?page="+p+"\">第"+Integer.toString(p+1)+"页</a>");
}
if (StartPage<j)
out.print ("|<a href=\"connectmysql.jsp?page=-"+Integer.toString(StartPage+1)+"\">后10页</a>");
out.print ("|");
