            data:{

                    reportDate:null,
                    todayNewMember :0,
                    totalMember :0,
                    thisWeekNewMember :0,

                }
            }
        })
    </script>

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

java 复制代码

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

java 复制代码

/**
     * 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：

java 复制代码

@Override
    public Map<Object, Object> getReportExcelResult(){
        Map<Object,Object> resultMap=new HashMap<>();
        try {
            System.out.println("=============================");
            //reportDate
            String data= Date2Utils.parseDate2String(new Date());
            System.out.println(data);
            resultMap.put("reportDate",data);
            //todayNewMember
            int count = memberMapper.selectCurrentDayMemberCount(data);
            resultMap.put("todayNewMember",count);
            //totalMember
            int totalMember=memberMapper.seelectTotalMember();
            resultMap.put("totalMember",totalMember);
            //thisWeekNewMember
            int thisWeekNewMember=memberMapper.selectthisWeekNewMember(data);
            resultMap.put("thisWeekNewMember",thisWeekNewMember);
            //thisMonthNewMember
            int thisMonthNewMember=memberMapper.selectthisMonthNewMember();
            resultMap.put("thisMonthNewMember",thisMonthNewMember);
            //todayOrderNumber
            int todayOrderNumber=orderSettingMapper.selecttodayOrderNumber();
            resultMap.put("todayOrderNumber",todayOrderNumber);
            //thisWeekOrderNumber
            int thisWeekOrderNumber=orderSettingMapper.selectthisWeekOrderNumber();
            resultMap.put("thisWeekOrderNumber",thisWeekOrderNumber);
            //thisMonthOrderNumber
            int thisMonthOrderNumber=orderSettingMapper.selectthisMonthOrderNumber();
            resultMap.put("thisMonthOrderNumber",thisMonthOrderNumber);
            //todayVisitsNumber
            int todayVisitsNumber=orderSettingMapper.selecttodayVisitsNumber();
            resultMap.put("todayVisitsNumber",todayVisitsNumber);
            //thisWeekVisitsNumber
            int thisWeekVisitsNumber=orderSettingMapper.selectthisWeekVisitsNumber();
            resultMap.put("thisWeekVisitsNumber",thisWeekVisitsNumber);
            //thisMonthVisitsNumber
            int thisMonthVisitsNumber=orderSettingMapper.selectthisMonthVisitsNumber();
            resultMap.put("thisMonthVisitsNumber",thisMonthVisitsNumber);
            //hotSetmeal
            List<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：

sql 复制代码

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

sql 复制代码

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

sql 复制代码

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

sql 复制代码

@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；

java 复制代码

 @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reportDate
            XSSFRow row = sheet.getRow(2);
            row.getCell(5).setCellValue(reportDate);//日期

            row = sheet.getRow(4);

            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
            }

            /**

        } 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

java 复制代码

 <!--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

2.状态码

++200：成功++

++三开头是重定向++

302：临时重定向（网站维护或更新、网站结构调整、负载均衡、SEO优化）

++四开头得是前端错误++

400：Bad Request 请求和服务器不匹配，参数类型不匹配

（请求的格式、语法或参数不符合服务器的要求）

401：没有http认证信息或者认证失败，

在HTTP协议中，401表示未认证的，通常是没有成功登录的

（身份验证失败、需要身份验证、访问权限不足被拒绝）

403：服务器拒绝请求，可能没有权限，403表示未授权的，

通常是已经登录，但是不具备相关的操作权限。

（验证通过但是权限不足、客户端问题）

404：找不到资源，资源路径有误（资源未找到、资源路径有误）

409：请求发生冲突(版本控制冲突、资源状态不匹配、并发请求冲突、权限问题)

++五开头的是后端错误++

500：内部服务器错误：这是服务器端的错误，与客户端的请求无关，

包括但不限于服务器程序错误、数据库问题、文件权限错误、服务器配置错误等。

502：网关错误，服务器作为网关或代理，从上游服务器收到无效响应
