使用POI外掛實現Excel含有合併行的匯入
阿新 • • 發佈：2018-11-29
一、要匯入的Excel樣式如下圖 紅色是合併行的單元格 紫色是正常單元格
需要實現的功能是作業型別存一張表 作業步驟另一張表 後面未合併的部分在第三張表中
二、EXCEL解析工具類

三 、controller層中匯入的方法
其中使用的 MultipartFile類可以去看一下他的api （別人的部落格：https://www.cnblogs.com/chenhonggao/p/8994598.html）
@RequestMapping(value = "/import") @ResponseBody public Map<String, Object> importExcel(@RequestParam("file") MultipartFile file, HttpServletRequest request) { Map<String, Object> resultMap = new HashMap<String, Object>(); User user = (User) session.getAttribute(Constants.SESSION_KEY_LOGIN_INFO); String fileName = file.getOriginalFilename();// 返回原來的檔名在客戶機的檔案系統 boolean isE2007 = false; // 判斷是否是excel2007格式 if (fileName.endsWith("xlsx")) { isE2007 = true; } int rowIndex = 0; int columnIndex = 0; try { InputStream input = file.getInputStream(); // 返回InputStream讀取檔案的內容。 Workbook wb = null; // 根據檔案格式(2003或者2007)來初始化 if (isE2007) { wb = new XSSFWorkbook(input); } else { wb = new HSSFWorkbook(input); } Sheet sheet = wb.getSheetAt(0); // 獲得第一個表單 // System.out.println("總行數:"+sheet.getLastRowNum()); List<CellRangeAddress> cras = ExcelUtils.getCombineCell(sheet); // isMergedRegion(Sheet sheet,int row ,int column);判斷是不是合併單元格 int count = sheet.getLastRowNum() + 1;// 總行數 // 從第三行開始取值 for (int i = 2; i < count; i++) { rowIndex = i; Row row = sheet.getRow(i); JSRManage jsr = new JSRManage();//風險管理實體 jsr.setJsrdangerName(ExcelUtils.getCellValue(row.getCell(1))); jsr.setCreateTime(DateUtils.getCurrentTime("yyyy-MM-dd HH:mm:ss")); jsr.setCreateName(user.getUsername()); jsr.setCreator(user.getId()); jsr.setJsrdangerCode(bussNumberService.getSerialNumber(Constants.JSR_CODE, null)); int countJsr = jsrManageService.insertJSR(jsr);//風險管理id // 第i行第二列是否合併行 if (ExcelUtils.isMergedRegion(sheet, i, 1)) { int lastRow = ExcelUtils.getRowNum(cras, sheet.getRow(i).getCell(1), sheet); for (; i <= lastRow; i++) { row = sheet.getRow(i); WorkStep workStep = new WorkStep();//作業步驟實體類 workStep.setJsrdangerId(countJsr); workStep.setJsrdangerStepName(ExcelUtils.getCellValue(row.getCell(2))); workStep.setCreator(user.getId()); workStep.setCreateName(user.getUsername()); workStep.setCreateTime(DateUtils.getCurrentTime("yyyy-MM-dd HH:mm:ss")); workStep.setLevel(i); int countWork = workStepService.insertWorkStep(workStep);// 步驟id SystemLogger.info(countWork > 0 ? "工作步驟新增成功!" : "工作步驟新增失敗!"); // 第i行第三列是否合併行 if (ExcelUtils.isMergedRegion(sheet, i, 2)) { int lastRow3 = ExcelUtils.getRowNum(cras, sheet.getRow(i).getCell(2), sheet); List<FewRisk> riskList = new ArrayList<FewRisk>(); for (; i <= lastRow3; i++) { row = sheet.getRow(i); FewRisk fewRisk = new FewRisk();//風險實體類 fewRisk.setJsrdangerStepId(countWork); fewRisk.setCreator(user.getId()); fewRisk.setCreateName(user.getUsername()); fewRisk.setCreateTime(DateUtils.getCurrentTime("yyyy-MM-dd HH:mm:ss")); fewRisk.setRiskName(ExcelUtils.getCellValue(row.getCell(3))); fewRisk.setPreventtName(ExcelUtils.getCellValue(row.getCell(4))); fewRisk.seteFrenqucy(Double.valueOf(ExcelUtils.getCellValue(row.getCell(5)))); fewRisk.setSeverity(Double.valueOf(ExcelUtils.getCellValue(row.getCell(6)))); fewRisk.setPossible(Double.valueOf(ExcelUtils.getCellValue(row.getCell(7)))); Double frenqucy = Double.valueOf(ExcelUtils.getCellValue(row.getCell(5))); Double severity = Double.valueOf(ExcelUtils.getCellValue(row.getCell(6))); Double possible = Double.valueOf(ExcelUtils.getCellValue(row.getCell(7))); Double riskLevelTemp = frenqucy*severity*possible; if (riskLevelTemp>=320) { fewRisk.setRiskLevel(Double.valueOf(5)); } else if(riskLevelTemp>=160){ fewRisk.setRiskLevel(Double.valueOf(4)); }else if(riskLevelTemp>=70){ fewRisk.setRiskLevel(Double.valueOf(3)); }else if(riskLevelTemp>=20){ fewRisk.setRiskLevel(Double.valueOf(2)); }else{ fewRisk.setRiskLevel(Double.valueOf(1)); } fewRisk.setLevel(i); riskList.add(fewRisk); } int total = fewRiskService.insertRiskList(riskList); SystemLogger.info(total > 0 ? "風險新增成功!" : "風險新增失敗!"); i--; } else { List<FewRisk> riskList = new ArrayList<FewRisk>(); row = sheet.getRow(i); FewRisk fewRisk = new FewRisk(); fewRisk.setJsrdangerStepId(countWork); fewRisk.setCreator(user.getId()); fewRisk.setCreateName(user.getUsername()); fewRisk.setCreateTime(DateUtils.getCurrentTime("yyyy-MM-dd HH:mm:ss")); fewRisk.setRiskName(ExcelUtils.getCellValue(row.getCell(3))); fewRisk.setPreventtName(ExcelUtils.getCellValue(row.getCell(4))); fewRisk.seteFrenqucy(Double.valueOf(ExcelUtils.getCellValue(row.getCell(5)))); fewRisk.setSeverity(Double.valueOf(ExcelUtils.getCellValue(row.getCell(6)))); fewRisk.setPossible(Double.valueOf(ExcelUtils.getCellValue(row.getCell(7)))); Double frenqucy = Double.valueOf(ExcelUtils.getCellValue(row.getCell(5))); Double severity = Double.valueOf(ExcelUtils.getCellValue(row.getCell(6))); Double possible = Double.valueOf(ExcelUtils.getCellValue(row.getCell(7))); Double riskLevelTemp = frenqucy*severity*possible;//計算風險等級 if (riskLevelTemp>=320) { fewRisk.setRiskLevel(Double.valueOf(5)); } else if(riskLevelTemp>=160){ fewRisk.setRiskLevel(Double.valueOf(4)); }else if(riskLevelTemp>=70){ fewRisk.setRiskLevel(Double.valueOf(3)); }else if(riskLevelTemp>=20){ fewRisk.setRiskLevel(Double.valueOf(2)); }else{ fewRisk.setRiskLevel(Double.valueOf(1)); } fewRisk.setLevel(i); riskList.add(fewRisk); int total = fewRiskService.insertRiskList(riskList); SystemLogger.info(total > 0 ? "風險新增成功!" : "風險新增失敗!"); } } i--; } else { row = sheet.getRow(i); WorkStep workStep = new WorkStep(); workStep.setJsrdangerId(count); workStep.setJsrdangerStepName(ExcelUtils.getCellValue(row.getCell(2))); workStep.setCreator(user.getId()); workStep.setCreateName(user.getUsername()); workStep.setCreateTime(DateUtils.getCurrentTime("yyyy-MM-dd HH:mm:ss")); workStep.setLevel(i); int countWork = workStepService.insertWorkStep(workStep);// 步驟id SystemLogger.info(countWork > 0 ? "工作步驟新增成功!" : "工作步驟新增失敗!"); } } } catch (Exception ex) { } resultMap.put(STATUS, STATUS_TRUE); resultMap.put(MSG, "檔案上傳成功"); return resultMap; }
四、html頁面 和 js（用的angular js）
/**
* @param file
* 上傳檔案
*/
$scope.upload = function (file) {
if(file != null && file != ""){
Upload.upload({
url: 'dangerJSRController/import',
data: {"sourceName": file.name.substring(0, file.name.lastIndexOf(".")) + ""},
file: file
}).progress(function (evt) {
//進度條
var progressPercentage = parseInt(100.0 * evt.loaded / evt.total);
console.log('progess:' + progressPercentage + '%' + evt.config.file.name);
}).success(function (data, status, headers, config) {
//上傳成功
// console.log('file ' + config.file.name + 'uploaded. Response: ' + data);
// console.info(data.path);
if(data.code == '1001'){
zsAlert($ZSPLAT, $scope, "上傳失敗!");
}else{
zsAlert($ZSPLAT, $scope, "上傳成功!");
clearItme($scope);
}
}).error(function (data, status, headers, config) {
//上傳失敗
console.log('error status: ' + status);
zsAlert($ZSPLAT, $scope, "上傳失敗!");
});}
};
<div style="width: 100px;" class="btn btn-primary btn-sm" ngf-select="upload($file)"> <span class="glyphicon glyphicon-cloud-upload"></span> <a style="color:#FFFFFF;text-decoration: none;" href="javascript:void(0);">匯入風險</a> </div>
實現的效果
