基于Javaweb实现ATM机系统开发实战（十三）交易记录查看实现

老规矩，先看前端传递怎样的数据，已经把要展示数据的变量名都改了：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page language="java"%>
<%@ page import="java.util.*"%>
<%@ page import="java.text.*"%>

创建servlet接受和处理请求：

package com.atm.servlet;

import com.atm.pojo.RunMessage;
import com.atm.pojo.User;
import com.atm.service.UserService;
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 UserService userService=new UserServiceImpl();

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    User user =(User)request.getSession().getAttribute("ua");
        try {
            List runMessages= userService.findRunMessage(user.getIcno());
            request.getSession().setAttribute("RunMessage",runMessages);
            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：

    //查询用户交易记录
    public  List findRunMessage (String icno) throws Exception;

实现类：

    //查询用户交易记录
    public  List findRunMessage (String icno) throws Exception{
        return userDao.findRunMessage(icno);
    }

数据层：

   //查询用户交易明细
    public List findRunMessage(String icno) throws Exception {
        Connection connection=DBUtils.getConnection();
        PreparedStatement preparedStatement = connection.prepareStatement("select * from runmessage where icno=?");
        preparedStatement.setString(1,icno);
        ResultSet rs=  preparedStatement.executeQuery();
        List  list=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));
            list.add(runMessage);
        }
        DBUtils.release(connection,preparedStatement,null);
        return list;
    }

然后重启系统，测试一下：

然后就发现交易明细正常显示啦~~
