2、开发笔记

1、框架的选择

首先在网上搜了很多的框架，移动端的优秀前端框架很多，但是大部分都是基于Vue.js来实现的，由于我还未学习Vue，所以就没有选择那些火热的框架，最终选择了一款多年前的框架---SUI Mobile。由于对前端框架不是很熟悉，所以使用起来还是有些不方便，也踩了不少坑，而去网上搜索解决问题时发现能找到的答案很少，由此看来选择一个热门的框架很重要，虽然技术不分好赖，但是使用人数多的技术生态好，解决问题很方便。下面是SUI的一些介绍：

SUI Mobile 是一套基于 Framework7 开发的UI库。它非常轻量、精美，只需要引入我们的CDN文件就可以使用，并且能兼容到 iOS 6.0+ 和 Android 4.0+，非常适合开发跨平台Web App。
轻量的UI库：SUI Mobile 非常轻量，核心库压缩Gzip后的JS、CSS网络传输体积总共只有52K，却提供了20+个常用的组件。对于只有HTML&CSS的组件，你只需要复制HTML代码既可以使用。他的大部分JS组件都是独立的 Zepto 插件，并且提供了 Zepto/jQuery 风格的API，你将会非常熟悉这种方式。
酷炫的IOS风格：我们的组件都是按照iOS风格设计的，所有有很多组件都是iOS独有的炫酷设计。

SUI是阿里巴巴共享业务事业部UED团队维护的，所以我也是相信他的强大并选择了这个框架。

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        doGet(request, response);
    }

}

7、展示用户信息界面servlet

package com.cashbook.web;

import java.io.IOException;
import java.sql.SQLException;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.cashbook.dao.UserDao;
import com.cashbook.domain.UserBean;

/**

@WebServlet("/userUI")
public class UserUIServlet extends HttpServlet {
    
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        
        Cookie[] cookies = request.getCookies();
        String useraccount = null;
        for (Cookie cookie : cookies) {
            if(cookie.getName().equals("account")) {
                useraccount = cookie.getValue();
                break;
            }
        }
        UserBean user = null;
        try {
            user = UserDao.userUI(useraccount);
        } catch (SQLException e) {
            e.printStackTrace();
        }
        request.setAttribute("user", user);
        request.getRequestDispatcher("/aboutme.jsp").forward(request, response);
        
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        doGet(request, response);
    }

}

4、dao层代码

1、账目记录操作的dao

package com.cashbook.dao;

import java.sql.SQLException;
import java.util.List;

import org.apache.commons.dbutils.QueryRunner;
import org.apache.commons.dbutils.handlers.BeanListHandler;

import com.cashbook.domain.NotesBean;
import com.cashbook.utils.MyDataSoureUtils;

public class NoteDao {

    public static void addNote(NotesBean note) throws SQLException {
        QueryRunner qr = new QueryRunner(MyDataSoureUtils.getDataSource());
        String sql = "insert into notes values(?,?,?,?,?)";
        qr.update(sql, note.getUseraccount(),note.getMoney(),note.getType(),note.getDate(),note.getRemarks());
    }


    public static List<NotesBean> inquire_add(String useraccount, String date_chaxun) throws SQLException {
        QueryRunner qr = new QueryRunner(MyDataSoureUtils.getDataSource());
        String sql = "select * from notes where useraccount=? and type=? and date between ? and ?";
        List<NotesBean> query = qr.query(sql, new BeanListHandler<NotesBean>(NotesBean.class), useraccount,"收入",date_chaxun+"-01",date_chaxun+"-31");
        return query;
    }


    public static List<NotesBean> inquire_down(String useraccount, String date_chaxun) throws SQLException {
        QueryRunner qr = new QueryRunner(MyDataSoureUtils.getDataSource());
        String sql = "select * from notes where useraccount=? and type=? and date between ? and ?";
        List<NotesBean> query = qr.query(sql, new BeanListHandler<NotesBean>(NotesBean.class), useraccount,"支出",date_chaxun+"-01",date_chaxun+"-31");
        return query;
    }


    public static List<NotesBean> inquire_all(String useraccount, String date_chaxun) throws SQLException {
        QueryRunner qr = new QueryRunner(MyDataSoureUtils.getDataSource());
        String sql = "select * from notes where useraccount=? and date between ? and ?";
        List<NotesBean> query = qr.query(sql, new BeanListHandler<NotesBean>(NotesBean.class), useraccount,date_chaxun+"-01",date_chaxun+"-31");
        return query;
    }

}

2、用户操作的dao

package com.cashbook.dao;

import java.sql.SQLException;

import org.apache.commons.dbutils.QueryRunner;
import org.apache.commons.dbutils.handlers.BeanHandler;
import org.apache.commons.dbutils.handlers.ScalarHandler;

import com.cashbook.domain.UserBean;
import com.cashbook.utils.MyDataSoureUtils;
import com.cashbook.utils.MyException;

public class UserDao {
    
    public static void addUser(UserBean user) throws SQLException, MyException {
        QueryRunner qr = new QueryRunner(MyDataSoureUtils.getDataSource());
        String sql = "insert into user values(?,?,?,?)";
        String sql2 = "select count(*) from user where account=?";
        Long query = (Long) qr.query(sql2, new ScalarHandler(), user.getAccount());
        int num = query.intValue();
        if(num!=0) {
            throw new MyException("该账号已存在!");
        }
        qr.update(sql, user.getId(),user.getAccount(),user.getPassword(),user.getUsername());
    }

    public static boolean login(String account, String password) throws SQLException {
        QueryRunner qr = new QueryRunner(MyDataSoureUtils.getDataSource());
        boolean pd = false;
        String sql = "select * from user where account=? and password=?";
        UserBean query = null;
        query = qr.query(sql, new BeanHandler<UserBean>(UserBean.class), account,password);
        if(query!=null) {
            pd = true;
        }
        return pd;
    }

    public static UserBean userUI(String useraccount) throws SQLException {
        QueryRunner qr = new QueryRunner(MyDataSoureUtils.getDataSource());
        String sql = "select * from user where account=?";
        UserBean query = qr.query(sql, new BeanHandler<UserBean>(UserBean.class), useraccount);
        return query;
    }

    public static void fixPassword(String useraccount, String password) throws SQLException {
        QueryRunner qr = new QueryRunner(MyDataSoureUtils.getDataSource());
        String sql = "update user set password=? where account=?";
        qr.update(sql, password,useraccount);
    }

}

3、总结

框架的选择比较重要。
长时间没写web以致开发过程中有些小问题都看不出来，果然还是要每天都学习。
开发难度并不大，处理好业务逻辑很重要，而我需要这方面的大量练习。
