二、项目介绍

项目描述：这是一个基于SpringBoot+Vue框架开发的充电桩管理系统。首先，这是一个前后端分离的项目，代码简洁规范，注释说明详细，易于理解和学习。其次，这项目功能丰富，具有一个充电桩管理系统该有的所有功能。

项目功能：此项目分为两个角色：普通用户和管理员。普通用户有登录注册、浏览个人数据统计信息、管理个人信息、浏览运营商信息、浏览电站信息、浏览充电桩信息、预约充电桩、报修充电桩、管理个人预约信息、开始充电、结束充电、查看个人订单信息、支付订单、查看个人报修信息、查看个人告警信息、查看留言信息等等功能。管理员有查看全部数据统计信息、管理所有用户信息、管理所有运营商信息、管理所有电站信息、管理所有充电桩信息、管理所有预约信息、管理所有订单信息、管理所有报修信息、管理所有告警信息、管理所有留言信息等等功能。

应用技术：SpringBoot + Vue3.0 + MySQL + MyBatis + Redis + ElementUI-Plus + Vite

运行环境：IntelliJ IDEA2019.3.5 + MySQL5.7（项目压缩包中自带) + Redis5.0.5（项目压缩包中自带） + JDK1.8 + Maven3.6.3（项目压缩包中自带）+ Node14.16.1（项目压缩包中自带）

四、主要代码

1. 分页获取预约数据代码

	/*** 分页获取预约数据* @param pageDTO* @return*/@Overridepublic ResponseDTO<PageDTO<AppointDTO>> getAppointList(PageDTO<AppointDTO> pageDTO) {AppointExample appointExample = new AppointExample();// 不知道当前页多少，默认为第一页if(pageDTO.getPage() == null){pageDTO.setPage(1);}// 不知道每页多少条记录，默认为每页5条记录if(pageDTO.getSize() == null){pageDTO.setSize(5);}AppointExample.Criteria c1 = appointExample.createCriteria();if(pageDTO.getParam() != null) {AppointDTO appointDTO = pageDTO.getParam();if(!CommonUtil.isEmpty(appointDTO.getUserId())) {c1.andUserIdEqualTo(appointDTO.getUserId());} else {UserExample userExample = new UserExample();userExample.createCriteria().andUsernameLike("%" + appointDTO.getUsername() + "%");List<String> userIdList = userMapper.selectByExample(userExample).stream().map(User::getId).collect(Collectors.toList());if(userIdList.size() == 0) {pageDTO.setTotal(0L);pageDTO.setList(new ArrayList<>());return ResponseDTO.success(pageDTO);}c1.andUserIdIn(userIdList);}if(!(CommonUtil.isEmpty(appointDTO.getChargeId())) && !"0".equals(appointDTO.getChargeId())) {c1.andChargeIdEqualTo(appointDTO.getChargeId());}}appointExample.setOrderByClause("create_time desc");PageHelper.startPage(pageDTO.getPage(), pageDTO.getSize());// 分页查出预约数据List<Appoint> appointList = appointMapper.selectByExample(appointExample);PageInfo<Appoint> pageInfo = new PageInfo<>(appointList);// 获取数据的总数pageDTO.setTotal(pageInfo.getTotal());// 将domain类型数据  转成 DTO类型数据List<AppointDTO> appointDTOList = CopyUtil.copyList(appointList, AppointDTO.class);for(AppointDTO appointDTO : appointDTOList) {User user = userMapper.selectByPrimaryKey(appointDTO.getUserId());appointDTO.setUserDTO(CopyUtil.copy(user, UserDTO.class));// 当前时间超过结束时间，且状态为待使用的预约，状态自动改为已取消// 当前时间超过结束时间，且状态为充电中的预约，状态自动改为已完成String[] splitTime = appointDTO.getTime().split("-");Date endDate = CommonUtil.getFormatterDate(CommonUtil.getFormatterDate(appointDTO.getDay(), "yyyy-MM-dd") + " " + splitTime[1], "yyyy-MM-dd HH:mm");Appoint appoint = CopyUtil.copy(appointDTO, Appoint.class);if(new Date().getTime() > endDate.getTime()) {if(AppointStateEnum.WAIT.getCode().equals(appointDTO.getState())) {appoint.setState(AppointStateEnum.CANCEL.getCode());appointDTO.setState(AppointStateEnum.CANCEL.getCode());} else if(AppointStateEnum.USE.getCode().equals(appointDTO.getState())) {appoint.setState(AppointStateEnum.OVER.getCode());appoint.setEndTime(endDate);appointDTO.setEndTime(endDate);appointDTO.setState(AppointStateEnum.OVER.getCode());Charge charge = chargeMapper.selectByPrimaryKey(appointDTO.getChargeId());BigDecimal totalPrice = charge.getPrice().multiply(new BigDecimal(DateUtil.between(appointDTO.getStartTime(), endDate, DateUnit.MINUTE)));Order order = new Order();order.setId(UuidUtil.getShortUuid());order.setCreateTime(new Date());order.setUserId(appointDTO.getUserId());order.setChargeId(appointDTO.getChargeId());order.setChargeName(appointDTO.getChargeName());order.setTotalPrice(totalPrice);if(orderMapper.insertSelective(order) == 0) {return ResponseDTO.errorByMsg(CodeMsg.ORDER_ADD_ERROR);}}appointMapper.updateByPrimaryKeySelective(appoint);}}pageDTO.setList(appointDTOList);return ResponseDTO.success(pageDTO);}

2.保存预约信息代码

	/*** 保存预约信息* @param appointDTO* @return*/@Overridepublic ResponseDTO<Boolean> saveAppoint(AppointDTO appointDTO) {// 进行统一表单验证CodeMsg validate = ValidateEntityUtil.validate(appointDTO);if (!validate.getCode().equals(CodeMsg.SUCCESS.getCode())) {return ResponseDTO.errorByMsg(validate);}Appoint appoint = CopyUtil.copy(appointDTO, Appoint.class);Charge charge = chargeMapper.selectByPrimaryKey(appoint.getChargeId());if(ChargeStateEnum.REPAIR.getCode().equals(charge.getState())) {return ResponseDTO.errorByMsg(CodeMsg.CHARGE_REPAIR_ERROR);}User user = userMapper.selectByPrimaryKey(appoint.getUserId());if(user == null) {return ResponseDTO.errorByMsg(CodeMsg.USER_NOT_EXIST);}if(CommonUtil.isEmpty(appoint.getId())) {// 添加操作if(user.getRate() < 80) {return ResponseDTO.errorByMsg(CodeMsg.RATE_NOT_ENOUGH);}appoint.setId(UuidUtil.getShortUuid());appoint.setCreateTime(new Date());// 判断预约日期时间段是否重复if(isDayExist(appoint, "")){return ResponseDTO.errorByMsg(CodeMsg.APPOINT_DAY_EXIST);}if(appointMapper.insertSelective(appoint) == 0) {return ResponseDTO.errorByMsg(CodeMsg.APPOINT_ADD_ERROR);}} else {// 修改操作// 判断预约日期时间段是否重复if(isDayExist(appoint, appoint.getId())){return ResponseDTO.errorByMsg(CodeMsg.APPOINT_DAY_EXIST);}if(appointMapper.updateByPrimaryKeySelective(appoint) == 0) {return ResponseDTO.errorByMsg(CodeMsg.APPOINT_EDIT_ERROR);}}return ResponseDTO.successByMsg(true, "保存成功！");}

3.修改订单状态代码

	/*** 修改订单状态* @param orderDTO* @return*/@Overridepublic ResponseDTO<Boolean> editOrderState(OrderDTO orderDTO) {if(CommonUtil.isEmpty(orderDTO.getId())) {return ResponseDTO.errorByMsg(CodeMsg.DATA_ERROR);}Order orderDB = orderMapper.selectByPrimaryKey(orderDTO.getId());Order order = CopyUtil.copy(orderDTO, Order.class);User user = userMapper.selectByPrimaryKey(orderDB.getUserId());if(user == null) {return ResponseDTO.errorByMsg(CodeMsg.USER_NOT_EXIST);}if(!OrderStateEnum.PAYED.getCode().equals(orderDB.getState()) && OrderStateEnum.PAYED.getCode().equals(order.getState())) {Rate rate = new Rate();rate.setId(UuidUtil.getShortUuid());if(user.getRate() + 5 >= 100) {user.setRate(100);} else {user.setRate(user.getRate() + 5);}rate.setNowScore(user.getRate());rate.setScore(5);rate.setType(RateTypeEnum.ADD.getCode());rate.setUserId(orderDB.getUserId());rate.setCreateTime(new Date());rate.setContent("成功支付，奖励信誉分5分！");if(rateMapper.insertSelective(rate) == 0) {return ResponseDTO.errorByMsg(CodeMsg.RATE_ADD_ERROR);}if(userMapper.updateByPrimaryKeySelective(user) == 0) {return ResponseDTO.errorByMsg(CodeMsg.USER_EDIT_ERROR);}}if(orderMapper.updateByPrimaryKeySelective(order) == 0) {return ResponseDTO.errorByMsg(CodeMsg.ORDER_EDIT_ERROR);}return ResponseDTO.success(true);}
