1、html
<td class="queryTdRight" style="width:22%;"> 交易年度： <input id="dealYear" name="dealYear" style="width: 140px"/> </td> <td class="queryTdRight" style="width:40%;"> 请选择文件导入： <input class="easyui-filebox" style="width:75%" name="uploadExcel" id="uploadExcel" data-options="onChange:function(){},prompt:‘选择文件‘,accept:‘application/vnd.ms-excel application/x-excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet‘"/> </td> <td align="left" style="padding-left:5px;"> <a href="javascript:uploadExcel()" class="easyui-linkbutton" data-options="iconCls:‘icon-upload‘">上 传</a> <a href="javascript:matching()" class="easyui-linkbutton" data-options="iconCls:‘icon-goto‘">匹 配</a> <a href="javascript:saveUploadExcel()" class="easyui-linkbutton" data-options="iconCls:‘icon-download‘">导 入</a> <a href="javascript:deleteData()" class="easyui-linkbutton" data-options="iconCls:‘icon-cancel‘">删 除</a> <a href="javascript:initTable(0)" class="easyui-linkbutton" data-options="iconCls:‘icon-search‘">查 询</a> </td>
2、js
/** * 上传按钮 * */ function uploadExcel(){ //得到上传文件的全路径 var fileName= $(‘#uploadExcel‘).filebox(‘getText‘); if(fileName==""){ $.messager.alert(‘提示‘,‘请选择上传文件！‘,‘info‘); return; } $.messager.progress({title:‘提示‘,msg:‘正在校验，请稍候...‘}); $.ajax({ url: basePath+"/demandForecast/selectTempData.action", data: "", type: "post", cache: false, dataType: "json", success: function (data) { $.messager.progress("close"); var d=data.resultData; if(d.length>0){ $.messager.confirm(‘提示‘, ‘数据已经存在，是否要覆盖？‘, function(r){ if (r){ importExcel(fileName); } }); }else{ importExcel(fileName); } }, error: function (error) { }, complete: function () { } }); } /** * 导入文件上传 */ function importExcel(fileName){ var dealYear= $(‘#dealYear‘).combobox(‘getValue‘); if(dealYear !=""){ //进行基本校验 //debugger; if(fileName==""){ $.messager.alert(‘提示‘,‘请选择上传文件！‘,‘info‘); }else{ //对文件格式进行校验 var f_content = fileName; var fileext=f_content.substring(f_content.lastIndexOf("."),f_content.length); fileext=fileext.toLowerCase(); //fileName=encodeURI(fileName); if (fileext==‘.xls‘ || fileext==‘.xlsx‘){ /*异步提交*/ $.messager.progress({title:‘提示‘,msg:‘正在上传文件，请稍候...‘}); $("#questionTypesManage").ajaxSubmit({ url:basePath+"/demandForecast/importToTemp.action?dealYear="+encodeURI(encodeURI(dealYear)), dataType:"text/html", type:‘post‘, clearForm:false, complete:function(data){ $.messager.progress("close"); data=""+data.responseText; var sd=data.split("\""); $.messager.alert(‘提示‘,sd[1],‘info‘, function() { initTable(); }); } }); }else{ $.messager.alert(‘提示‘,‘请选择xls/xlsx格式文件！‘,‘info‘); $(‘#uploadExcel‘).filebox(‘setValue‘,‘‘); } } }else{ $.messager.alert(‘提示‘,‘请选择日期！‘,‘info‘); } }
3、struts xml
<action name="importToTemp" class="com.icss.action.demandForecast.DemandForecastAction" method="importToTemp"> <result name="importResult" type="json"> <param name="contentType"> text/html </param> <param name="root">mark</param> </result> </action>
4、action
public String importToTemp(){ try { demandForecastService.saveMonthSalePlanImportTemp(new FileInputStream(uploadExcel),dealYear); mark="上传成功"; operationLogService.saveLog(ConstantConfig.DEMAND_FORECAST_IMPORT_CODE, ConstantConfig.DEMAND_FORECAST_IMPORT_NAME, "[电脑][上传][成功]"); } catch (Exception e) { e.printStackTrace(); mark="上传失败,模板数据不规范"; try { operationLogService.saveLog(ConstantConfig.DEMAND_FORECAST_IMPORT_CODE, ConstantConfig.DEMAND_FORECAST_IMPORT_NAME, "[电脑][上传][失败]["+e.getMessage()+"]"); } catch (Exception e1) { e1.printStackTrace(); } } return "importResult"; }
5、service
@Override public void saveMonthSalePlanImportTemp(FileInputStream is, String dealYear) throws Exception { //先清空临时表 String condition="1=1"; baseDao.delete("WP_DEMAND_FORECAST_IMPORT_TEMP", condition); Workbook wb = WorkbookFactory.create(is); Sheet sheet = wb.getSheetAt(0);//获取工作簿 DemandForecastImportTemp demandForecastImportTemp=null; for (int i = 0,rowNum = sheet.getLastRowNum(); i < rowNum; i++) {//迭代行 demandForecastImportTemp = new DemandForecastImportTemp(); Row row = sheet.getRow(i+1);//获取工作簿中的行（不取第一行） boolean isLasttextRow = false;//是否最后一行 for (int j = 0,cellNum = row.getLastCellNum(); j < cellNum; j++) {//迭代列 Cell cell = row.getCell(j);//取得列中的值 if (cell == null) { break; } String cellValue = dataType(cell); if (j == 0 && StringUtils.isEmpty(cellValue)) { isLasttextRow = true; break; } setData(demandForecastImportTemp, cellValue, j, dealYear); } if (isLasttextRow) { break; } //保存数据 demandForecastImportTemp.setDealYear(dealYear); this.save(demandForecastImportTemp); } } private void save(DemandForecastImportTemp demandForecastImportTemp) { ArrayList<String> columns=new ArrayList<String>(); ArrayList<Object> values=new ArrayList<Object>(); columns.add("ORG_ID"); values.add(demandForecastImportTemp.getOrgId()); columns.add("ORG_NAME"); values.add(demandForecastImportTemp.getOrgName()); columns.add("IND_ID"); values.add(demandForecastImportTemp.getIndId()); columns.add("IND_NAME"); values.add(demandForecastImportTemp.getIndName()); columns.add("CIG_CODE"); values.add(demandForecastImportTemp.getCigCode()); columns.add("CIG_NAME"); values.add(demandForecastImportTemp.getCigName()); columns.add("CIG_CLASS"); values.add(demandForecastImportTemp.getCigClass()); columns.add("CIG_PRICE"); values.add(demandForecastImportTemp.getCigPrice()); columns.add("YEAR_DEMAND"); values.add(demandForecastImportTemp.getYearDemand()); columns.add("PRE_HALFYEAR_STORE"); values.add(demandForecastImportTemp.getPreHalfyearStore()); columns.add("HALFYEAR_DEMAND_FORECAST"); values.add(demandForecastImportTemp.getHalfyearDemandForecast()); columns.add("YEAR_END_STORE"); values.add(demandForecastImportTemp.getYearEndStore()); columns.add("NEXT_HALFYEAR_DEMAND"); values.add(demandForecastImportTemp.getNextHalfyearDemand()); columns.add("NEXT_HALFYEAR_AUDIT_DEMAND"); values.add(demandForecastImportTemp.getNextHalfyearAuditDemand()); columns.add("CHECK_STATUS"); values.add(demandForecastImportTemp.getCheckStatus()); columns.add("DEAL_YEAR"); values.add(demandForecastImportTemp.getDealYear()); baseDao.insert("WP_DEMAND_FORECAST_IMPORT_TEMP", columns, values); } //判断excel单元格内容的格式，并对其进行转换，以便插入数据库 private final String dataType(Cell cell){ switch (cell.getCellType()) { case 0: return String.valueOf(cell.getNumericCellValue()); case 1: return cell.getStringCellValue(); case 2: return String.valueOf(cell.getDateCellValue()); case 4: return String.valueOf(cell.getBooleanCellValue()); case 5: return String.valueOf(cell.getErrorCellValue()); } return ""; } private final void setData(DemandForecastImportTemp demandForecastImportTemp, String cellValue,int j,String dealYear){ if (j == 0) { demandForecastImportTemp.setOrgName(cellValue); } else if (j == 1) { demandForecastImportTemp.setCigName(cellValue); } else if (j == 2) { demandForecastImportTemp.setCigCode(cellValue); } else if (j == 3) { demandForecastImportTemp.setIndName(cellValue); } else if (j == 4) { double cigClass = Double.valueOf(StringUtils.isEmpty(cellValue) ? "0" : cellValue); demandForecastImportTemp.setCigClass(cigClass); } else if (j == 5) { double cigPrice = Double.valueOf(StringUtils.isEmpty(cellValue) ? "0" : cellValue); demandForecastImportTemp.setCigPrice(cigPrice); } else if (j == 6) { double yearDemand = Double.valueOf(StringUtils.isEmpty(cellValue) ?

"0" : cellValue); demandForecastImportTemp.setPreHalfyearStore(preHalfyearStore); } else if (j == 8) { double halfyearDemandForecast = Double.valueOf(StringUtils.isEmpty(cellValue) ?

"0" : cellValue); demandForecastImportTemp.setYearEndStore(yearEndStore); } else if (j == 10) { double nextHalfyearDemand = Double.valueOf(StringUtils.isEmpty(cellValue) ? "0" : cellValue); demandForecastImportTemp.setNextHalfyearDemand(nextHalfyearDemand); }else if (j == 11) { double nextHalfyearAuditDemand = Double.valueOf(StringUtils.isEmpty(cellValue) ? "0" : cellValue); demandForecastImportTemp.setNextHalfyearAuditDemand(nextHalfyearAuditDemand); } demandForecastImportTemp.setDealYear(dealYear); demandForecastImportTemp.setCheckStatus(0); }
