</html>

后端代码，先查询表上的数据，封装成对应的前端需要的形式的Map集合

@GetMapping("/getBusinessReportData")public Result getBusinessReportData(){Map<Object,Object> reportData=memberService.getReportExcelResult();return new Result(true,"success",reportData);}

/*** reportDate:null,*   todayNewMember :0,*  totalMember :0,*  thisWeekNewMember :0,*  thisMonthNewMember :0,*  todayOrderNumber :0,*  todayVisitsNumber :0,*  thisWeekOrderNumber :0,*  thisWeekVisitsNumber :0,*  thisMonthOrderNumber :0,*  thisMonthVisitsNumber :0,*  hotSetmeal :[* {name:'阳光爸妈升级肿瘤12项筛查（男女单人）体检套餐',setmeal_count:200,proportion:0.222},* {name:'阳光爸妈升级肿瘤12项筛查体检套餐',setmeal_count:200,proportion:0.222}* ]

数据形式如上，封装过程如下：

@Overridepublic Map<Object, Object> getReportExcelResult(){Map<Object,Object> resultMap=new HashMap<>();try {System.out.println("=============================");//reportDateString data= Date2Utils.parseDate2String(new Date());System.out.println(data);resultMap.put("reportDate",data);//todayNewMemberint count = memberMapper.selectCurrentDayMemberCount(data);resultMap.put("todayNewMember",count);//totalMemberint totalMember=memberMapper.seelectTotalMember();resultMap.put("totalMember",totalMember);//thisWeekNewMemberint thisWeekNewMember=memberMapper.selectthisWeekNewMember(data);resultMap.put("thisWeekNewMember",thisWeekNewMember);//thisMonthNewMemberint thisMonthNewMember=memberMapper.selectthisMonthNewMember();resultMap.put("thisMonthNewMember",thisMonthNewMember);//todayOrderNumberint todayOrderNumber=orderSettingMapper.selecttodayOrderNumber();resultMap.put("todayOrderNumber",todayOrderNumber);//thisWeekOrderNumberint thisWeekOrderNumber=orderSettingMapper.selectthisWeekOrderNumber();resultMap.put("thisWeekOrderNumber",thisWeekOrderNumber);//thisMonthOrderNumberint thisMonthOrderNumber=orderSettingMapper.selectthisMonthOrderNumber();resultMap.put("thisMonthOrderNumber",thisMonthOrderNumber);//todayVisitsNumberint todayVisitsNumber=orderSettingMapper.selecttodayVisitsNumber();resultMap.put("todayVisitsNumber",todayVisitsNumber);//thisWeekVisitsNumberint thisWeekVisitsNumber=orderSettingMapper.selectthisWeekVisitsNumber();resultMap.put("thisWeekVisitsNumber",thisWeekVisitsNumber);//thisMonthVisitsNumberint thisMonthVisitsNumber=orderSettingMapper.selectthisMonthVisitsNumber();resultMap.put("thisMonthVisitsNumber",thisMonthVisitsNumber);//hotSetmealList<Map<String,String>> hotSetmeal=new ArrayList<>();hotSetmeal=orderSettingMapper.selecthotSetmeal();resultMap.put("hotSetmeal",hotSetmeal);System.out.println(resultMap);} catch (Exception e) {throw new RuntimeException(e);}return resultMap;}

以下是一组时间范围查询的相关的SQL记录：

    @Select("SELECT COUNT(0) " +"FROM`t_order`  " +"WHERE orderDate = CURDATE() AND orderStatus='已到诊'")int selecttodayVisitsNumber();

 @Select("SELECT COUNT(*) " +"FROM `t_order` " +"WHERE orderDate >= DATE_SUB(CURDATE(), INTERVAL 1 WEEK) " +"  AND orderDate <= CURDATE() AND orderStatus='已到诊';")int selectthisWeekVisitsNumber();

 @Select("SELECT COUNT(*) " +"FROM `t_order` " +"WHERE orderDate >= DATE_SUB(CURDATE(), INTERVAL 1 MONTH) " +"AND orderDate <= CURDATE() AND orderStatus='已到诊';")int selectthisMonthVisitsNumber();

@Select("SELECT \n" +"    s.`name` AS 'name',\n" +"    COUNT(0) AS 'setmeal_count',\n" +"    COUNT(0) * 1.0 / (SELECT COUNT(*) FROM `t_order`) AS 'proportion'\n" +"    \n" +"FROM \n" +"    `t_order` o \n" +"LEFT JOIN \n" +"    `t_setmeal` s ON o.`setmeal_id` = s.`id`\n" +"GROUP BY \n" +"    s.`id` LIMIT 4;")List<Map<String, String>> selecthotSetmeal();

然后是根据查到的数据导入定制好的格式的Excel表格，并可以使之导出；

 @RequestMapping("/exportBusinessReport")public void exportBusinessReport(HttpServletRequest request, HttpServletResponse response) {Map<Object, Object> result = memberService.getReportExcelResult();String reportDate = (String) result.get("reportDate");Integer todayNewMember = (Integer) result.get("todayNewMember");Integer totalMember = (Integer) result.get("totalMember");Integer thisWeekNewMember = (Integer) result.get("thisWeekNewMember");Integer thisMonthNewMember = (Integer) result.get("thisMonthNewMember");Integer todayOrderNumber = (Integer) result.get("todayOrderNumber");Integer thisWeekOrderNumber = (Integer) result.get("thisWeekOrderNumber");Integer thisMonthOrderNumber = (Integer) result.get("thisMonthOrderNumber");Integer todayVisitsNumber = (Integer) result.get("todayVisitsNumber");Integer thisWeekVisitsNumber = (Integer) result.get("thisWeekVisitsNumber");Integer thisMonthVisitsNumber = (Integer) result.get("thisMonthVisitsNumber");List<Map> hotSetmeal = (List<Map>) result.get("hotSetmeal");//获得Excel模板文件绝对路径String temlateRealPath = request.getSession().getServletContext().getRealPath("template") +File.separator + "report_template.xlsx";/*** 读取模板文件创建Excel表格对象* File.separator：根据操作系统获取文件分隔符（Windows为\，Linux/Unix为/）*/XSSFWorkbook workbook = null;//初始化XSSFWorkbook对象，用于表示Excel文件。try {//读取Excel模板文件workbook = new XSSFWorkbook(new FileInputStream(new File(temlateRealPath)));//获取Excel的第一个工作表：XSSFSheet sheet = workbook.getSheetAt(0);//示例：获取第3行（索引从0开始），第6个单元格（索引从0开始），并设置其值为reportDateXSSFRow row = sheet.getRow(2);row.getCell(5).setCellValue(reportDate);//日期row = sheet.getRow(4);row.getCell(5).setCellValue(todayNewMember);//新增会员数（本日）row.getCell(7).setCellValue(totalMember);//总会员数row = sheet.getRow(5);row.getCell(5).setCellValue(thisWeekNewMember);//本周新增会员数row.getCell(7).setCellValue(thisMonthNewMember);//本月新增会员数row = sheet.getRow(7);row.getCell(5).setCellValue(todayOrderNumber);//今日预约数row.getCell(7).setCellValue(todayVisitsNumber);//今日到诊数row = sheet.getRow(8);row.getCell(5).setCellValue(thisWeekOrderNumber);//本周预约数row.getCell(7).setCellValue(thisWeekVisitsNumber);//本周到诊数row = sheet.getRow(9);row.getCell(5).setCellValue(thisMonthOrderNumber);//本月预约数row.getCell(7).setCellValue(thisMonthVisitsNumber);//本月到诊数int rowNum = 12;for (Map map : hotSetmeal) {//热门套餐String name = (String) map.get("name");Long setmeal_count = (Long) map.get("setmeal_count");BigDecimal proportion = (BigDecimal) map.get("proportion");row = sheet.getRow(rowNum++);row.getCell(4).setCellValue(name);//套餐名称row.getCell(5).setCellValue(setmeal_count);//预约数量row.getCell(6).setCellValue(proportion.doubleValue());//占比}/*** 获取Servlet的输出流。* 设置响应的内容类型为Excel文件。* 设置响应头，指示浏览器将响应作为附件下载，并指定下载的文件名为report.xlsx。* 将workbook的内容写入输出流。*/ServletOutputStream out = response.getOutputStream();response.setContentType("application/vnd.ms-excel");response.setHeader("content-Disposition", "attachment;filename=report.xlsx");workbook.write(out);/*** 刷新输出流，确保所有数据都被写出。* 关闭输出流和workbook对象，释放资源。*/out.flush();out.close();workbook.close();} catch (IOException e) {throw new RuntimeException(e);}}

知识补充：

1.使用【always-use-default-target="true"】

配置在springSecurity的登陆界面配置中

 <!--配置自己的登录页面--><security:form-login login-page="/login.html" username-parameter="username"password-parameter="password" login-processing-url="/login2.do"default-target-url="/pages/main.html" authentication-failure-url="/login.html"always-use-default-target="true"/>

可以避免登陆后跳转未放行的404或304界面
