soso移动营业大厅（纯后端+MySQL数据库+JDBC）-编程知识

一、项目需求

中国移动,中国联通,中国电信是国内3大通信运营商,每个运营商都提供了不同的品牌套餐来应对不同的用户群,比如北京移动主要有全球通,神州行,动感地带等3大品牌套餐,每种套餐的内容和费用不同,嗖嗖移动是一个假定的通信运营商,提供了话痨套餐,网虫套餐,超人套餐,各种套餐所包含的服务内容及费用如下表:

品牌套餐	话痨套餐	网虫套餐	超人套餐
通话时长(分钟)	600	0	300
上网流量	0	20	10
短信条数(条)	100	0	50
费用(元/月)	58	68	78

如实际使用中超出套餐内包含的通话时长,短信条数和上网流量,则按一下规则计费:

超出的通话: 0.2元/分
超出的短信:0.1元/条
超出的上网流量:0.1元/MB

本任务实现的"嗖嗖移动业务大厅"提供了嗖嗖移动用户的常用功能,包括新用户注册,本月账单查询,套餐余量查询,打印消费详情,套餐变更,办理退网,话费充值,查看消费记录,查看话费说明等功能.另外,还可以模拟用户通话,上网,发送短信的场景进行相应的扣费并记录消费信息.各功能介绍如下表:

菜单级别	功能	描述
主菜单	用户登录	输入正确的手机号码和密码进入二级菜单列表
主菜单	用户注册	录入信息并开卡,用户输入的信息包括:选择卡号,选择套餐类型,输入用户名和密码,预存话费金额(预存话费金额必须满足以支付所选套餐的一个月的费用)
主菜单	使用嗖嗖	输入正确的手机号码和密码之后,随机进入本号码所属套餐可以支持的一个场景,消费套餐余量或者话费余额,并记录消费信息.当话费余额不足时,抛出异常提醒用户充值
主菜单	话费充值	输入正确的用户名和密码之后,可为该卡号充值
主菜单	资费说明	提供各品牌套餐所包含的通话时长,上网流量,短信条数,月费用等
主菜单	退出系统	提出本系统
二级菜单	本月账单查询	可查询该卡号的套餐费用,实际消费金额,账户余额
二级菜单	套餐余量查询	可查询该卡号的套餐余量
二级菜单	打印消费详情	输入正确的卡号和密码后,可打印当前卡号用户的消费详单, 使用输出流把用户信息输出到文件
二级菜单	套餐变更	可变更为其他套餐类型,变更后话费余额需减去变更后的套餐费用,余额不足时需要给出信息提示,套餐变更后重新统计卡中实际消费数据以及当月消费金额
二级菜单	办理退网	输入正确的卡号和密码后,可以从已注册的号码列表中删除本号码,并退出系统

二、项目需求分析

2.1 登陆

让用户输入手机号码, 密码,
根据手机号码,密码到数据库: tb_mobole_card查询
如果没有记录: 登录失败, 错误提示: 手机号码或者密码错误
如果有记录,但是状态是1(冻结): 登录失败, 错误提示: 该手机号码已冻结,请联系工作人员
登录成功, 进入到二级菜单

2.2 注册

查询所有可用卡 tb_card
查询所有的套餐类型, 用户选择套餐类型,
根据用户选择的套餐类型, 查询套餐信息
用户输入用户,密码. 输入充值金额
根据输入金额与用户选择套餐的月租比较, 输入金额小于月租, 错误提示, 用户再重新输入
如果大于等于, 往用户卡表(tb_mobole_card)插入一条记录
修改tb_card表,用户选择该手机号码的卡状态设置为不可用
往充值记录表中添加一条充值记录
显示办卡成功, 输出用户卡相关信息,以及套餐信息
跳转到一级菜单

2.3 使用soso

输入手机号码查询到用户卡信息查询套餐 2. 如果卡冻结状态, 无法使用嗖嗖显示错误信息 3. 查询所有的场景, 随机一个场景进行模拟得到场景类型, 数据
假设随机第一个场景, 通话场景, 打90分钟电话,

剩余免费余量 = 套餐最大免费量 - 月消费当月消费量(查询月消费)
如果用户的卡的剩余免费余量 > =场景的数量, 不需要扣钱, 在月消费记录表, 当月增加使用量的值
如果用户的卡的剩余免费余量 < 场景的数量, 需要扣钱, 在月消费记录表, 当月增加使用量的值,超出的部分进行扣费, 修改的用户卡的余额
往消费记录表进行记录本次消费消费记录表

2.4 套餐变更

查询所有的套餐类型
根据当前登录的手机号码, 查询当前用户卡信息
用户选择套餐类型，根据用户现在的套餐明细得到套餐类型
判断用户选择的套餐是否是用户卡现在套餐,如果是,提示,
如果不是,根据用户选择的套餐类型,查询对应的套餐明细
判断用户卡的余额是否满足该套餐的月租, 如果不满足, 提示
如果满足, 更换套餐, 修改用户卡信息(套餐,余额)
打印用户新套餐的明细

三、代码展示

1.系统大体结构

2.使用的jar包

commons-dbutils-1.7.jar	mysql-connector-java-5.1.47.jar
提供了简化数据库操作的工具	连接 MySQL 数据库的 JDBC 驱动程序

这两个 JAR 包通常用于 Java 应用程序中与数据库进行交互的过程中

hamcrest- 2.1jar	junit-4.12.jar
提供更加灵活和可读性强的测试断言方式	用于编写和运行单元测试

这两个库通常会一起被用于编写高质量的测试代码，以确保代码的正确性和稳定性。

3.完整代码
