一、预约挂号详情

1、需求分析

1、接口分析

（1）根据预约周期，展示可预约日期数据，按分页展示

（2）选择日期展示当天可预约列表（该接口后台已经实现过）

2、页面展示分析

（1）分页展示可预约日期，根据有号、无号、约满等状态展示不同颜色，以示区分

（2）可预约最后一个日期为即将放号日期，根据放号时间页面展示倒计时

2、后台api接口

2.3 添加controller方法

在HospitalApiController类添加方法

@Autowiredprivate ScheduleService scheduleService;@ApiOperation(value = "获取可预约排班数据")@GetMapping("auth/getBookingScheduleRule/{page}/{limit}/{hoscode}/{depcode}")public Result getBookingSchedule(@ApiParam(name = "page", value = "当前页码", required = true)@PathVariable Integer page,@ApiParam(name = "limit", value = "每页记录数", required = true)@PathVariable Integer limit,@ApiParam(name = "hoscode", value = "医院code", required = true)@PathVariable String hoscode,@ApiParam(name = "depcode", value = "科室code", required = true)@PathVariable String depcode) {return Result.ok(scheduleService.getBookingScheduleRule(page, limit, hoscode, depcode));}@ApiOperation(value = "获取排班数据")@GetMapping("auth/findScheduleList/{hoscode}/{depcode}/{workDate}")public Result findScheduleList(@ApiParam(name = "hoscode", value = "医院code", required = true)@PathVariable String hoscode,@ApiParam(name = "depcode", value = "科室code", required = true)@PathVariable String depcode,@ApiParam(name = "workDate", value = "排班日期", required = true)@PathVariable String workDate) {return Result.ok(scheduleService.getDetailSchedule(hoscode, depcode, workDate));}

当天放号时间一到，则预约周期加一（预约时间要始终保持10天，所以需要加一）；

假设预约周期是1天，若医院12点放号，那么在12点前进行预约，可以预约今天的号；在12点之后进行预约，预约周期就要+1，只能预约明天的号

dateList->总的可预约日期的集合，pageDateList->当前页可预约天数的集合，start->当前页的首个天数的索引，end-1->当前页最后一个天数的索引

当前页iPage对象若要包含位置正确的各个天数对象（比如：属于第二页第二个位置的应该是哪个Date对象），需要借助start与end来从dataList中复制对应位置的Date对象到自己的集合中

//封装的是 获取可预约日期的分页信息private IPage<Date> getListDate(Integer page, Integer limit, BookingRule bookingRule) {//1. 获取当天new Date（）放号时间 ：时间戳形式，DateTime releaseTime = this.getDateTime(new Date(), bookingRule.getReleaseTime());//每天放号时间，如早上八点30分//2. 获取预约周期Integer cycle = bookingRule.getCycle();//如果当天放号时间已经过去，预约周期从后一天开始计算，周期+1if(releaseTime.isBeforeNow()){//超过当前时间点cycle += 1;}//dateList->总的可预约日期的集合，注意这里根据业务需要只显示日期的，如09-09//所以我们需要截取DateTime的日期部分//3. 获取可预约的所有日期，如10天，最后一天显示即将放号倒计时List<Date> dateList = new ArrayList<>();//需要按照时间顺序显示的for(int i =0;i < cycle; i++){//遍历预约周期次//每 循环一次，增加一天DateTime curDateTime = new DateTime().plusDays(i);//DateTime增加一天的方法System.out.println("curDateTime:"+curDateTime);//将DateTime转成string，并截取日期String dateString = curDateTime.toString("yyyy-MM-dd");//将DateTime(string 形式的date) 转成 Date 并添加到dateListdateList.add(new DateTime(dateString).toDate() );}//4. 因为预约周期不同，每页显示日期最多7天数据，超过7天进行分页List<Date> pageDateList = new ArrayList<>();//每页开始位置int start = (page - 1) * limit;//每页结束的位置int end = (page - 1) * limit + limit;//增加一个limit的容量周期//如果可以显示数据小于7，直接显示if(end > dateList.size()){//直接显示end = dateList.size();}//5. 将dateList数据放到pageDateListfor (int i = start; i < end; i++) {//将dateList数据放到pageDateListpageDateList.add(dateList.get(i));}// 6. 如果可以显示的数据大于7，进行分页//Page(long current, long size, long total)IPage<Date> iPage= new com.baomidou.mybatisplus.extension.plugins.pagination.Page<>(page, 7, dateList.size());//7. IPage<T> setRecords(List<T> records)iPage.setRecords(pageDateList);return iPage;}
