快速學習POI-POI報表導出

5 POI報表導出

5.1 需求分析

完成當月人事報表的導出：包含當月入職員工信息，離職員工信息

5.2 人事報表導出

5.2.1 步驟分析

1. 構造Excel表格數據
2. 建立工做簿
3. 建立sheet
4. 建立行對象
5. 建立單元格對象
6. 填充數據，設置樣式
7. 下載

5.2.2 代碼實現

（1）配置controller

@RequestMapping(value = "/export/{month}", method = RequestMethod.GET)
    public void export(@PathVariable(name = "month") String month) throws Exception {
        //1.構造數據
        List<EmployeeReportResult> list =
userCompanyPersonalService.findByReport(companyId,month+"%");
        //2.建立工做簿
        XSSFWorkbook workbook = new XSSFWorkbook();
        //3.構造sheet
        String[] titles = {"編號", "姓名", "手機","最高學歷", "國家地區", "護照號", "籍貫", 
"生日", "屬相","入職時間","離職類型","離職緣由","離職時間"};
        Sheet sheet = workbook.createSheet();
        Row row = sheet.createRow(0);
        AtomicInteger headersAi = new AtomicInteger();
        for (String title : titles) {
            Cell cell = row.createCell(headersAi.getAndIncrement());
            cell.setCellValue(title);
       }
        AtomicInteger datasAi = new AtomicInteger(1);
        Cell cell = null;
        for (EmployeeReportResult report : list) {
            Row dataRow = sheet.createRow(datasAi.getAndIncrement());
            //編號
            cell = dataRow.createCell(0);
            cell.setCellValue(report.getUserId());
            //姓名
            cell = dataRow.createCell(1);
            cell.setCellValue(report.getUsername());
            //手機
            cell = dataRow.createCell(2);
            cell.setCellValue(report.getMobile());
            //最高學歷
            cell = dataRow.createCell(3);
            cell.setCellValue(report.getTheHighestDegreeOfEducation());
            //國家地區
            cell = dataRow.createCell(4);
            cell.setCellValue(report.getNationalArea());
            //護照號
            cell = dataRow.createCell(5);
            cell.setCellValue(report.getPassportNo());
            //籍貫
            cell = dataRow.createCell(6);
            cell.setCellValue(report.getNativePlace());
            //生日
            cell = dataRow.createCell(7);
            cell.setCellValue(report.getBirthday());
            //屬相
            cell = dataRow.createCell(8);
            cell.setCellValue(report.getZodiac());
            //入職時間
            cell = dataRow.createCell(9);
            cell.setCellValue(report.getTimeOfEntry());
            //離職類型
            cell = dataRow.createCell(10);
            cell.setCellValue(report.getTypeOfTurnover());
            //離職緣由
            cell = dataRow.createCell(11);
            cell.setCellValue(report.getReasonsForLeaving());
            //離職時間
            cell = dataRow.createCell(12);
            cell.setCellValue(report.getResignationTime());
       }
        String fileName = URLEncoder.encode(month+"人員信息.xlsx", "UTF-8");
        response.setContentType("application/octet-stream");
        response.setHeader("content-disposition", "attachment;filename=" + new
String(fileName.getBytes("ISO8859-1")));
        response.setHeader("filename", fileName);
        workbook.write(response.getOutputStream());
   }

（2）添加service

//根據企業id和年月查詢
    public List<EmployeeReportResult> findByReport(String companyId, String month) {
        return userCompanyPersonalDao.findByReport(companyId,month);
   }

（3）dao層實現

 @Query(value = "select new 
com.ihrm.domain.employee.response.EmployeeReportResult(a,b) " +
            "FROM UserCompanyPersonal a LEFT JOIN EmployeeResignation b ON 
a.userId=b.userId WHERE a.companyId = ?1 AND a.timeOfEntry LIKE ?2 OR 
(b.resignationTime LIKE ?2)")
    List<EmployeeReportResult> findByReport(String companyId, String month);
