还是老规矩，先看前端页面查看需要传递哪些参数，并且把逻辑有问题的部分进行修改~

创建一个PageBean对象，封装这些数据：

private int pageNum;//当前页页码，从请求传过来
private int pageSize; //每页显示的数据条数
private int totalRecord;//总的记录条数，查询数据库得到的数据

private int startIndex;//从哪开始拿
//把每页要显示的数据放集合里
private List<T> list;
//分页显示的页数 1-5中的1和5
private int start;
private int end;

}

this.pageNum = pageNum;
}
public int getPageSize() {

}

之前我们把查询交易明细的代码都写到Userservice中了，其实应该写到RunMessageService中，对应的数据层和实现类也是同样的操作~
然后对交易记录的Servlet进行修改，插入分页功能：
package com.atm.servlet;
import com.atm.pojo.PageBean;
import com.atm.pojo.RunMessage;
import com.atm.pojo.User;
import com.atm.service.RunMessageService;
import com.atm.service.UserService;
import com.atm.service.impl.RunMessageServiceImpl;
import com.atm.service.impl.UserServiceImpl;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.annotation.*;
import java.io.IOException;
import java.util.List;
//查询交易记录
@WebServlet("/serchDetaile")
public class SerchDetaileServlet extends HttpServlet {
private RunMessageService runMessageService=new RunMessageServiceImpl();
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
User user =(User)request.getSession().getAttribute("ua");
try {
//分页处理
//获得页码
String pageNum=request.getParameter("pageNum");
int page=1;
if(pageNum!=null){
page=Integer.parseInt(pageNum);
}
//每页显示的条数
int pagesize=5;
//计算分页的总条数
int totalRecord= runMessageService.countRunmessage(user.getIcno());
//封装pagebean对象
PageBean<RunMessage> pageBean=new PageBean<>(page,pagesize,totalRecord);
//查询当前页的数据，并设置到pageBean中返回
List<RunMessage> lists =runMessageService.findRunMessageByPage(user.getIcno(),page,pagesize);
pageBean.setList(lists);
request.getSession().setAttribute("pageBean",pageBean);
response.sendRedirect("/changepage/UserDetaile.jsp");
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request,response);
}
}
接口：
//查询交易记录总条数
public int countRunmessage(String icno) throws Exception{
return runMessageDao.countRunMessage(icno);
}
//查询当前页数据
public List<RunMessage> findRunMessageByPage(String icno,int page, int pagesize) throws Exception{
return runMessageDao.findRunMessageByPage(icno,page,pagesize);
}数据层：
//用户交易记录总条数
public int countRunMessage(String icno) throws Exception{
Connection connection=DBUtils.getConnection();
PreparedStatement preparedStatement = connection.prepareStatement("select count(1) from runmessage where icno=?");
preparedStatement.setString(1,icno);
ResultSet rs= preparedStatement.executeQuery();
int totalRecord=0;
if (rs.next()){
totalRecord=rs.getInt(1);
}
DBUtils.release(connection,preparedStatement,null);
return totalRecord;
}
//查询当前页的交易记录
public List<RunMessage> findRunMessageByPage(String icno,int page, int pagesize) throws Exception {
Connection connection=DBUtils.getConnection();
int startIndex =(page-1)*pagesize;
PreparedStatement preparedStatement = connection.prepareStatement("select * from runmessage where icno=? limit ?,?");
preparedStatement.setString(1,icno);
preparedStatement.setInt(2,startIndex);
preparedStatement.setInt(3,pagesize);
ResultSet rs= preparedStatement.executeQuery();
List<RunMessage> lists=new ArrayList<>();
while (rs.next()){
RunMessage runMessage=new RunMessage();
runMessage.setId(rs.getInt(1));
runMessage.setIcno(rs.getString(2));
runMessage.setRm_date(rs.getString(3));
runMessage.setRm_currency(rs.getString(4));
runMessage.setRm_balance(rs.getDouble(5));
runMessage.setRm_rest(rs.getDouble(6));
lists.add(runMessage);
}
DBUtils.release(connection,preparedStatement,null);
return lists;
}再随便添加几条数据方便测试效果：
重启一下系统，然后就发现功能实现啦！~
