上傳使用flash插件
需要jquery.uploadify.min.js，uploadify.css，poi-ooxml-3.8-20120326.jar等
jsp頁面：
<%@include file="/uploadDeclare.jsp"%> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <style type="text/css"> .uploadify { float: left; margin: 0 10px; }</style> <script type="text/javascript"> //導入功能 $(function() { $("#uploadFile").uploadify({ buttonClass : ‘‘, fileSizeLimit : ‘51200KB‘, uploader : ‘${basePath}core/upload!uploadFile.action‘, // 服務器端處理地址 swf : ‘${basePath}js/uploadify/uploadify.swf‘, // 上傳使用的 FlashbuttonText : "導入", buttonCursor : ‘hand‘, fileObjName : ‘uploadify‘,// 上傳參數名稱 後臺action裏面的屬性uploadify fileTypeExts : "*.xls;*.xlsx", // 擴展名 fileTypeDesc : "請選擇 文件格式", removeTimeout : 1, // 文件說明 auto : true, // 選擇之後，自動開始上傳 multi : false, // 是否支持同時上傳多個文件 queueSizeLimit : 1, // 允許多文件上傳的時候，同時上傳文件的個數 queueID : ‘queueID‘, onUploadSuccess : function(file, data, response) { var data = jQuery.parseJSON(data); if (data.error == 1) { ldDialog.alert(data.message); } else { $.ajax({ url : "${basePath}uploadDocumentAction/uploadDocument!importManyOverallPlan.action", type : "post", dataType : "json", data : { filePath : data.url, fileName : data.newFileName, proId : "${proId}", }, async : false, success : function(r) { if (r.code == ‘success‘) { ldDialog.tips("導入成功！"); document.pagerForm.submit(); } else { ldDialog.tips("導入失敗！"); } } }); } } }); }); </script> </head> <td> <input type="button" id="uploadFile" class="ldBtnGray" value="導入" /> <a href="${basePath}/upload/template/template13.xlsx" download="template13.xlsx"> <span style=‘float: right; margin-right: 20px; margin-top: 10px; font-size: 18px; color: #2891d2;‘>模板下載</span> </a> </td>
uploadDeclare.jsp
<%@page language="java" contentType="text/html; charset=utf-8"%> <base href="${pageContext.request.scheme}://${pageContext.request.serverName}:${pageContext.request.serverPort}${pageContext.request.contextPath}/" /> <LINK href="${basePath}plugins/uploadify/uploadify.css" type="text/css" rel="stylesheet" /> <script language="javascript" type="text/javascript"> //防止客戶端緩存文件，造成uploadify.js不更新，而引起的“喔唷，崩潰啦” document.write ("<script type=‘text/javascript‘ " + "src=‘${basePath}plugins/uploadify/jquery.uploadify.min.js?" + new Date () + "‘><\/script>"); </script> <style> .uploadify-box { width: 130px; margin: 0px; margin-top: 10px; } </style>
效果頁面：
excel文件放在eclipse-workspace\report\WebRoot\upload\template\template13.xlsx目錄下，都有的字段：
jsp頁面 url : "${basePath}uploadDocumentAction/uploadDocument!importManyOverallPlan.action"對應的類，uploadDocumentAction
其中base類DesigndrawOverallPlanPo中書協的屬性和屬性的get(),set()方法，可自行編寫
/** * 批量導入 * @param modelMap * @param request * @return * @throws ParseException */ @ResponseBody @RequestMapping("uploadDocument!importManyOverallPlan.action") public JSONObject importManyOverallPlan(ModelMap modelMap, HttpServletRequest request) throws ParseException { String filePath = this.getStringParameter("filePath"); String fileName = this.getStringParameter("fileName"); String proId = this.getStringParameter("proId"); final JSONObject result = new JSONObject(); final UploadDocument uploadDocument = this.parameterToPoPrefix(UploadDocument.class); ProApprovalPo proApproval = this.proApprovalBaseService.queryProApprovalById(proId); User user = this.getSessionUser(); String proName = ""; boolean success = false; String code = ""; if(user != null && proApproval != null) { String abPath = request.getSession().getServletContext().getRealPath("/"); filePath = abPath + filePath; List<DesigndrawOverallPlanPo> designdrawOverallPlans = new ReadInfoTableExcel().getExcelToOverallPlan(filePath); proName = proApproval.getProName(); for(int i=0;i<designdrawOverallPlans.size();i++) { DesigndrawOverallPlanPo designdrawOverallPlan = designdrawOverallPlans.get(i); //首先校驗excel文件中的項目id和項目名稱是否正確 //還有計劃開始時間要小於等於計劃結束時間 //且時間格式2018-01-02要正確 //計劃開始時間和計劃結束時間是date類型與導入時類型（java.long.String）不匹配， //所以現在導入時，計劃開始時間值:reserved1，計劃結束時間：reserved2 //.trim():取消空格 if(StringUtils.isEmpty(designdrawOverallPlan.getProId()) || !proId.equals(designdrawOverallPlan.getProId().trim())) { continue; }else if(StringUtils.isEmpty(designdrawOverallPlan.getProName()) || !proName.equals(designdrawOverallPlan.getProName().trim())) { continue; }else if(StringUtils.isNotEmpty(designdrawOverallPlan.getReserved1()) && StringUtils.isNotEmpty(designdrawOverallPlan.getReserved2())) { java.text.SimpleDateFormat format = new java.text.SimpleDateFormat("yyyy-MM-dd"); String startAcTime = designdrawOverallPlan.getReserved1().trim(); String endAcTime = designdrawOverallPlan.getReserved2().trim(); //計算持續時長(天):計劃結束時間-計劃開始時間 if(validationTimeFormat(startAcTime) && validationTimeFormat(endAcTime)) { int day = (int)((format.parse(endAcTime).getTime() - format.parse(startAcTime).getTime())/(24 * 60 * 60 * 1000)) + 1; if(day<1) { continue; }else { designdrawOverallPlan.setStartAcTime(format.parse(startAcTime)); designdrawOverallPlan.setEndAcTime(format.parse(endAcTime)); designdrawOverallPlan.setContinueDate(day); } } } designdrawOverallPlan.setReserved1(null); designdrawOverallPlan.setReserved2(null); designdrawOverallPlan.setProId(designdrawOverallPlan.getProId().trim()); designdrawOverallPlan.setProName(designdrawOverallPlan.getProName().trim()); designdrawOverallPlan.setBaseInfo(user); designdrawOverallPlanBaseService.insertDesigndrawOverallPlan(designdrawOverallPlan); success = true; } } result.put("code", code); return result; } /** * 校驗時間格式為2018-01-02 * @param time * @return */ public boolean validationTimeFormat(String time) { boolean bool = false; Pattern pattern = Pattern.compile("[0-9]*"); if(time != null && time.length() == 10) { //校驗前四位是否為數字 if(pattern.matcher(time.substring(0, 4)).matches()) { //校驗第五位是- if("-".indexOf(time.substring(4, 5))!=-1) { //校驗第6,7位是否為數字 if(pattern.matcher(time.substring(5,7)).matches()) { //校驗第8位是否為- if("-".indexOf(time.substring(7, 8))!=-1) { //校驗第9,10位是否為數字 if(pattern.matcher(time.substring(8, 10)).matches()) { bool = true; } } } } } } return bool; }
方法：ReadInfoTableExcel().getExcelToOverallPlan(filePath);
/** * 獲取excel裏的信息 * @param filepath * @param filetype * @param uuid * @return */ public List<DesigndrawOverallPlanPo> getExcelToOverallPlan(String filePath) { //這兒導入使用兩個方法原因： //excel版本有03版本和07版本的區別，文件後綴名分別為.xls和.xlsx。它們對應的POI中的Workbook也是不同的， //分別是HSSFWorkbook和XSSFWorkbook；對於不同版本的EXCEL文檔要使用不同的工具類 try{ return addExcelToOverallPlanXSSF1(filePath); }catch(Exception e){ try{ return addExcelToOverallPlanXSSF2(filePath); }catch (Exception e1){ return null; } } }
方法：addExcelToOverallPlanXSSF1 和 addExcelToOverallPlanXSSF2，這兒利用到了反射的方法使屬性和字段值一一對應起來。
/** * 批量導入 方法1 * @param filePath * @return * @throws IOException */ public List<DesigndrawOverallPlanPo> addExcelToOverallPlanXSSF1(String filePath) throws IOException{ List<ZuobiaoInfo> zuobiaoInfos = new ArrayList<>(); List<DesigndrawOverallPlanPo> designdrawOverallPlans = new ArrayList<DesigndrawOverallPlanPo>(); XSSFWorkbook swb = new XSSFWorkbook(filePath); XSSFSheet sheet = swb.getSheetAt(0); zuobiaoInfos = new TableinfoTest().getOverallPlan(); //獲取excel文件中的行數 int rowsNumber = this.getnumber(filePath); for(int i=0;i<rowsNumber;i++) { boolean flag = true; DesigndrawOverallPlanPo designdrawOverallPlan = new DesigndrawOverallPlanPo(); for(int j=0;j<zuobiaoInfos.size();j++) { Class c = designdrawOverallPlan.getClass(); Class[] cargs = new Class[1]; int cellnumber = zuobiaoInfos.get(j).getZongzuobiao(); try { Object realArgs = this.getXSSFSheetExcelvalue(i+1, cellnumber, sheet); if(realArgs!=null) { cargs[0] = realArgs.getClass(); String method = zuobiaoInfos.get(j).getMethod(); Method m = c.getMethod(method, cargs); Object[] inArgs = new Object[1]; inArgs[0] = realArgs; m.invoke(designdrawOverallPlan, inArgs); } } catch (Exception e) { e.printStackTrace(); flag = false; break; } } if(flag) { designdrawOverallPlans.add(designdrawOverallPlan); } } return designdrawOverallPlans; } /** * 批量導入 方法2 * @param filePath * @return * @throws IOException */ public List<DesigndrawOverallPlanPo> addExcelToOverallPlanXSSF2(String filePath) throws IOException{ List<ZuobiaoInfo> zuobiaoInfos = new ArrayList<>(); List<DesigndrawOverallPlanPo> designdrawOverallPlans = new ArrayList<DesigndrawOverallPlanPo>(); HSSFWorkbook xwb = new HSSFWorkbook(new FileInputStream(filePath)); HSSFSheet sheet= xwb.getSheetAt(0); zuobiaoInfos = new TableinfoTest().getOverallPlan(); //獲取excel文件中的行數 int rowsNumber = this.getnumber(filePath); for(int i=0;i<rowsNumber;i++) { boolean flag = true; DesigndrawOverallPlanPo designdrawOverallPlan = new DesigndrawOverallPlanPo(); for(int j=0;j<zuobiaoInfos.size();j++) { Class c = designdrawOverallPlan.getClass(); Class[] cargs = new Class[1]; int cellnumber = zuobiaoInfos.get(j).getZongzuobiao(); try { Object realArgs=this.getHSSFSheetExcelvalue(i+1, cellnumber, sheet); if(realArgs!=null) { cargs[0] = realArgs.getClass(); String method = zuobiaoInfos.get(j).getMethod(); if(!realArgs.toString().equals("")){ Method m = c.getMethod(method, cargs); Object[] inArgs = new Object[1]; inArgs[0] = realArgs; m.invoke(designdrawOverallPlan, inArgs); }else{ flag = false; break; } } } catch (Exception e) { e.printStackTrace(); flag = false; break; } } if(flag) { designdrawOverallPlans.add(designdrawOverallPlan); } } return designdrawOverallPlans; }
方法：this.getnumber(filePath);
public int getnumber(String filepath) { try{ XSSFWorkbook xwb = new XSSFWorkbook(filepath); XSSFSheet sheet = xwb.getSheetAt(0); int allsheetnumber=sheet.getLastRowNum(); System.out.println(allsheetnumber); return allsheetnumber; }catch (Exception e){ e.printStackTrace(); try { HSSFWorkbook xwb1 = new HSSFWorkbook(new FileInputStream(filepath)); HSSFSheet sheet1= xwb1.getSheetAt(0); int allsheetnumber1=sheet1.getLastRowNum(); return allsheetnumber1; }catch (Exception e1){ e1.printStackTrace(); return 0; } } }
方法：this.getHSSFSheetExcelvalue(i+1, cellnumber, sheet);
public String getHSSFSheetExcelvalue(int rownumber,int cellnumber,HSSFSheet sheet){ String str=null; if(sheet.getRow(rownumber)!=null){ if(sheet.getRow(rownumber).getCell(cellnumber)!=null){ str=sheet.getRow(rownumber).getCell(cellnumber).toString(); } } return str; }
方法：TableinfoTest().getOverallPlan()，其中setProId等是base類DesigndrawOverallPlanPo中屬性proId的set()方法。
public class TableinfoTest { List<ZuobiaoInfo> overallPlan = new ArrayList<ZuobiaoInfo> (Arrays.asList( new ZuobiaoInfo("setProId", "項目編號", 0), new ZuobiaoInfo("setProName", "項目名稱", 1), new ZuobiaoInfo("setWorkContent", "工作內容", 2), new ZuobiaoInfo("setReserved1", "計劃開始時間", 3), new ZuobiaoInfo("setReserved2", "計劃結束時間", 4), new ZuobiaoInfo("setRemarks", "備註", 5) )); public List<ZuobiaoInfo> getOverallPlan() { return overallPlan; } public void setOverallPlan(List<ZuobiaoInfo> overallPlan) { this.overallPlan = overallPlan; } }
類：ZuobiaoInfo
package com.landicorp.pilot.action.readexcel; public class ZuobiaoInfo { public String Method;//方法名 public String name; public int zongzuobiao;//縱坐標 public ZuobiaoInfo(){ } public ZuobiaoInfo(String Method, String name ,int zongzuobiao){ this.Method=Method; this .zongzuobiao=zongzuobiao; this .name=name; } public int getZongzuobiao() { return zongzuobiao; } public void setZongzuobiao(int zongzuobiao) { this.zongzuobiao = zongzuobiao; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getMethod() { return Method; } public void setMethod(String method) { Method = method; } }
