一，步驟
1.導入：
一.ftl <form id="form" action="" enctype="multipart/form-data" method="post" > <input type="file" id="fileID" name="fileName" class="btn dropdown-toggle btn-primary" style="width: 220px; float:left;" /> <input type="hidden" name="projectId" id="projectId" value=""> <input type="button" value="導入源聲" onclick="importList();" class="btn dropdown-toggle btn-success" style="margin-left:20px;"/> </form> 註意：後臺獲取屬性的值，必須指定 name = "" 二.js function importList() { var filePath = $("#fileID").val(); if (filePath == ‘‘) { alert(‘請選擇文件!‘); return; } if(pnationId == ‘-1‘ || nationId == ‘-1‘){ alert(‘請選擇國家!‘); return; } var form = $("#form"); var projectId = GetQueryString("projectId "); $(‘#projectId‘).val(projectId); form.attr("action", "/nps/analysis/import"); form.attr("method", "POST"); form.submit(); } //獲取projectId function GetQueryString(name) { var reg= new RegExp("(^|&)"+ name +"=([^&]*)(&|$)"); var r = window.location.search.substr(1).match(reg); if (r != null) return unescape(r[2]); return null; } 三.controller @RequestMapping(value="/analysis/import",method = RequestMethod.POST) public String importSource(HttpServletRequest request,@RequestParam("fileName") CommonsMultipartFile file, Integer projectId){ InputStream in =null; String msg = ""; try { in = file.getInputStream(); msg = npsSourceAnalysisService.importList(in, file.getOriginalFilename(),pnationId,nationId); in.close(); } catch (IOException e) { e.printStackTrace(); logger.info(e.getMessage()); msg = "導入失敗！"; } finally { if (in != null) { try { in.close(); // 關閉流 } catch (IOException e) { logger.debug("in close IOException:" + e.getMessage()); } } } return "redirect:/nps/analysis/list?projectId="+projectId+"&msg="+msg; } 四.service public String importList(InputStream in,String fileName); @Transactional public String importList(InputStream in, String fileName,Integer pnationId,Integer nationId) { String[][] table = null; String msg = null; try { table = ExcelUtils.readExcel(in,fileName,0); } catch (Exception e) { e.printStackTrace(); return "文件導入失敗，請檢查文件格式！"; } Map<String,Integer> tableColumMap = new HashMap<String, Integer>(); if (CheckUtils.isNullOrBlank(table) || table.length == 0) { return "表格中沒有任何數據！"; } if (table.length == 1) { return "表格中只存在表頭數據！"; } //校驗導入文件內容 for (int i = 0; i < table[0].length; i++) { String cell = table[0][i].trim(); tableColumMap.put(cell, i); } List<String> errorMsgs = new ArrayList<String>(); String[] titles ={"ID","描述","產品名稱","型號","版本","時間","次數","得分（問題1）","得分（問題2）"}; for (int i = 0; i < titles.length; i++) { String title = titles[i]; if(!tableColumMap.containsKey(title)){ errorMsgs.add("Excel表格表頭列有誤,不存在"+title+"列，請修改Excel後導入"); if(errorMsgs.size() >= 10) return "導入文件表頭不正確，請檢查後重新導入！"; } } if (errorMsgs.size() == 0) { NPSSourceAnalysis npsSourceAnalysis=new NPSSourceAnalysis(); for (int i = 1; i < table.length; i++) { String sourceID = table[i][tableColumMap.get("ID")].trim(); String descript = table[i][tableColumMap.get("描述")].trim(); String product = table[i][tableColumMap.get("名稱")].trim(); String inner = table[i][tableColumMap.get("型號")].trim(); String ROM = table[i][tableColumMap.get("版本")].trim(); String createTime = table[i][tableColumMap.get("時間")].trim(); String SN = table[i][tableColumMap.get("SN")].trim(); String CSR = table[i][tableColumMap.get("得分（問題1）")].trim(); String recommend = table[i][tableColumMap.get("得分（問題2）")].trim(); npsSourceAnalysis.setSourceID(Integer.parseInt(sourceID)); npsSourceAnalysis.setDescript(descript); npsSourceAnalysis.setProduct(product); npsSourceAnalysis.setInnerVersion(inner); npsSourceAnalysis.setOuterVersion(outer); npsSourceAnalysis.setROM(ROM); npsSourceAnalysis.setCreateTime(createTime); npsSourceAnalysis.setSN(SN); npsSourceAnalysis.setCSR(Integer.parseInt(CSR)); npsSourceAnalysis.setRecommend(Integer.parseInt(recommend)); npsSourceAnalysis.setHandled(0); npsSourceAnalysis.setAbroad(0); npsSourceAnalysis.setPnationId(pnationId); npsSourceAnalysis.setNationId(nationId); nPSSourceAnalysisMapper.insert(npsSourceAnalysis); } } else{ for (String errorMsg : errorMsgs) { msg = msg + errorMsg +";"; } } return msg; } 五,需要的工具類 ExcelUtils.readExcel() 六.依賴 <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>3.16-beta1</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>3.16-beta1</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.1</version> </dependency <!-- https://mvnrepository.com/artifact/org.samba.jcifs/jcifs --> <dependency> <groupId>org.samba.jcifs</groupId> <artifactId>jcifs</artifactId> <version>1.2.19</version> </dependency>
2.導出：
