工作台

接口设计

新建admin/WorkSpaceController


/*** 工作台*/
@RestController
@RequestMapping("/admin/workspace")
@Slf4j
@Api(tags = "工作台相关接口")
public class WorkSpaceController {@Autowiredprivate WorkspaceService workspaceService;/*** 工作台今日数据查询* @return*/@GetMapping("/businessData")@ApiOperation("工作台今日数据查询")public Result<BusinessDataVO> businessData(){//获得当天的开始时间LocalDateTime begin = LocalDateTime.now().with(LocalTime.MIN);//获得当天的结束时间LocalDateTime end = LocalDateTime.now().with(LocalTime.MAX);BusinessDataVO businessDataVO = workspaceService.getBusinessData(begin, end);return Result.success(businessDataVO);}/*** 查询订单管理数据* @return*/@GetMapping("/overviewOrders")@ApiOperation("查询订单管理数据")public Result<OrderOverViewVO> orderOverView(){return Result.success(workspaceService.getOrderOverView());}/*** 查询菜品总览* @return*/@GetMapping("/overviewDishes")@ApiOperation("查询菜品总览")public Result<DishOverViewVO> dishOverView(){return Result.success(workspaceService.getDishOverView());}/*** 查询套餐总览* @return*/@GetMapping("/overviewSetmeals")@ApiOperation("查询套餐总览")public Result<SetmealOverViewVO> setmealOverView(){return Result.success(workspaceService.getSetmealOverView());}
}

新建WorkspaceService

public interface WorkspaceService {/*** 根据时间段统计营业数据* @param begin* @param end* @return*/BusinessDataVO getBusinessData(LocalDateTime begin, LocalDateTime end);/*** 查询订单管理数据* @return*/OrderOverViewVO getOrderOverView();/*** 查询菜品总览* @return*/DishOverViewVO getDishOverView();/*** 查询套餐总览* @return*/SetmealOverViewVO getSetmealOverView();}

新建WorkspaceServiceImpl

@Service
@Slf4j
public class WorkspaceServiceImpl implements WorkspaceService {@Autowiredprivate OrderMapper orderMapper;@Autowiredprivate UserMapper userMapper;@Autowiredprivate DishMapper dishMapper;@Autowiredprivate SetmealMapper setmealMapper;/*** 根据时间段统计营业数据* @param begin* @param end* @return*/public BusinessDataVO getBusinessData(LocalDateTime begin, LocalDateTime end) {/*** 营业额：当日已完成订单的总金额* 有效订单：当日已完成订单的数量* 订单完成率：有效订单数 / 总订单数* 平均客单价：营业额 / 有效订单数* 新增用户：当日新增用户的数量*/Map map = new HashMap();map.put("begin",begin);map.put("end",end);//查询总订单数Integer totalOrderCount = orderMapper.countByMap(map);map.put("status", Orders.COMPLETED);//营业额Double turnover = orderMapper.sumByMap(map);turnover = turnover == null? 0.0 : turnover;//有效订单数Integer validOrderCount = orderMapper.countByMap(map);Double unitPrice = 0.0;Double orderCompletionRate = 0.0;if(totalOrderCount != 0 && validOrderCount != 0){//订单完成率orderCompletionRate = validOrderCount.doubleValue() / totalOrderCount;//平均客单价unitPrice = turnover / validOrderCount;}//新增用户数Integer newUsers = userMapper.countByMap(map);return BusinessDataVO.builder().turnover(turnover).validOrderCount(validOrderCount).orderCompletionRate(orderCompletionRate).unitPrice(unitPrice).newUsers(newUsers).build();}/*** 查询订单管理数据** @return*/public OrderOverViewVO getOrderOverView() {Map map = new HashMap();map.put("begin", LocalDateTime.now().with(LocalTime.MIN));map.put("status", Orders.TO_BE_CONFIRMED);//待接单Integer waitingOrders = orderMapper.countByMap(map);//待派送map.put("status", Orders.CONFIRMED);Integer deliveredOrders = orderMapper.countByMap(map);//已完成map.put("status", Orders.COMPLETED);Integer completedOrders = orderMapper.countByMap(map);//已取消map.put("status", Orders.CANCELLED);Integer cancelledOrders = orderMapper.countByMap(map);//全部订单map.put("status", null);Integer allOrders = orderMapper.countByMap(map);return OrderOverViewVO.builder().waitingOrders(waitingOrders).deliveredOrders(deliveredOrders).completedOrders(completedOrders).cancelledOrders(cancelledOrders).allOrders(allOrders).build();}/*** 查询菜品总览** @return*/public DishOverViewVO getDishOverView() {Map map = new HashMap();map.put("status", StatusConstant.ENABLE);Integer sold = dishMapper.countByMap(map);map.put("status", StatusConstant.DISABLE);Integer discontinued = dishMapper.countByMap(map);return DishOverViewVO.builder().sold(sold).discontinued(discontinued).build();}/*** 查询套餐总览** @return*/public SetmealOverViewVO getSetmealOverView() {Map map = new HashMap();map.put("status", StatusConstant.ENABLE);Integer sold = setmealMapper.countByMap(map);map.put("status", StatusConstant.DISABLE);Integer discontinued = setmealMapper.countByMap(map);return SetmealOverViewVO.builder().sold(sold).discontinued(discontinued).build();}
}

DishMapper

     * 根据条件统计菜品数量* @param map* @return*/Integer countByMap(Map map);

DishMapper.xml

    <select id="countByMap" resultType="java.lang.Integer">select count(id) from dish<where><if test="status != null">and status = #{status}</if><if test="categoryId != null">and category_id = #{categoryId}</if></where></select>

导出运营数据Excel报表

产品原型

接口设计

ReportController

    /*** 导出运营数据报表* @param response*/@GetMapping("/export")@ApiOperation("导出运营数据报表")public void export(HttpServletResponse response){reportService.exportBusinessData(response);}

ReportService

    /*** 导出运营数据报表* @param response*/void exportBusinessData(HttpServletResponse response);

ReportServiceImpl

   /*** 导出运营数据报表* @param response*/public void exportBusinessData(HttpServletResponse response) {//1、查询数据库，获取营业数据---查询最近30天的运营数据LocalDate dateBegin = LocalDate.now().minusDays(30);LocalDate dateEnd = LocalDate.now().minusDays(1);//查询概览数据BusinessDataVO businessDataVO = workspaceService.getBusinessData(LocalDateTime.of(dateBegin, LocalTime.MIN), LocalDateTime.of(dateEnd, LocalTime.MAX));//2、通过POI将数据写入到Excel文件中InputStream in = this.getClass().getClassLoader().getResourceAsStream("template/运营数据报表模版.xlsx");try {//基于模版文件创建一个新的Excel文件XSSFWorkbook excel = new XSSFWorkbook(in);//获取表格文件的Sheet页XSSFSheet sheet = excel.getSheet("Sheet1");//填充数据---时间sheet.getRow(1).getCell(1).setCellValue("时间：" + dateBegin + "至" +dateEnd);//获得第四行XSSFRow row = sheet.getRow(3);row.getCell(2).setCellValue(businessDataVO.getTurnover());row.getCell(4).setCellValue(businessDataVO.getOrderCompletionRate());row.getCell(6).setCellValue(businessDataVO.getNewUsers());//获得第五行row = sheet.getRow(4);row.getCell(2).setCellValue(businessDataVO.getValidOrderCount());row.getCell(4).setCellValue(businessDataVO.getUnitPrice());//填充明细数据for (int i = 0; i < 30; i++) {LocalDate date = dateBegin.plusDays(i);//查询某一天的营业数据BusinessDataVO businessData = workspaceService.getBusinessData(LocalDateTime.of(date, LocalTime.MIN), LocalDateTime.of(date, LocalTime.MAX));//获得某一行row = sheet.getRow(7 + i);row.getCell(1).setCellValue(date.toString());row.getCell(2).setCellValue(businessData.getTurnover());row.getCell(3).setCellValue(businessData.getValidOrderCount());row.getCell(4).setCellValue(businessData.getOrderCompletionRate());row.getCell(5).setCellValue(businessData.getUnitPrice());row.getCell(6).setCellValue(businessData.getNewUsers());}//3、通过输出流将Excel文件下载到浏览器ServletOutputStream out = response.getOutputStream();excel.write(out);//关闭资源out.close();excel.close();} catch (IOException e) {e.printStackTrace();}}
