    </div>
    



2.Action代码：
//当前页面
private int currentPage = 1;

//页面大小
private int pageSize = 15;

//总页数
static int countPage = 1;

//countPage的getter和setter方法
public int getCurrentPage() {
  return currentPage;
}
public void setCurrentPage(int currentPage){
  this.currentPage =currentPage;
}

//execute()中的代码
  //查询总页数
  countPage =DAO对象.pageCount(表名,pageSize, 数据库连接);

  request.setAttribute("countPage",countPage);
  request.setAttribute("currentPage",currentPage);

3.DAO代码

public int pageCount(String tableName, intpageSize,
DataBaseServicedataBaseService) {

int count =dataBaseService.findRows("select count(*) from "
+tableName);

return count / pageSize +1;
}
