實現功能：

　　1、Excel模板下載

　　2、導入excel

一、jsp效果和代碼

 1 <form id="uploadForm" target="frameFile" class="bs-docs-example form-horizontal" method="post" action="<%=path %>/webCenter.do" enctype="multipart/form-data">
 2                 <input type="hidden" id="conId" name="conId" value="<%=conId%>">
 3                 <input type="hidden" id="code" name="code" value="<%=code%>">
 4                 <input type="hidden" name="method" value="insertUserInfo">
 5                 <table cellpadding="0" cellspacing="0" border="0" style="width:600px;margin:20px auto;text-algin:left;">
 6                 <tr><td colspan="4"><input id="dyId" type="hidden"/></td></tr>
 7                 <tr><td colspan="3"><a href="/center/file/userInfoModel.xlsx" id="downloadModel" name="downloadModel" style="margin-left:7px;"><u>點擊下載人員模板</u></a></td></tr>
 8                 <tr><td colspan="4"><br/></td></tr>
 9                 <tr><td colspan="3"><input id="files" name="files" type="file" style="width:200px;"/></td></tr><!-- background:url('/center/images/uploadImg.png') no-repeat 0px 10px; -->
10                 <tr><td colspan="4"><br/></td></tr>
11                 <tr>
12                     <td colspan="4" style="text-align: center;">
13                     <hr style="width:720px;border-width: 0.3px;margin-left:-10px;">
14                         <button id="tiJiao" type="button" class="czbtn" style="width:100px;font-size: 16px;">導入</button>
15                     </td>
16                 </tr>
17                 </table>
18             </form>

二、js代碼

 1 $("#tiJiao").click(function(){
 2             if($("#files").val() == ""){
 3                 alert("請選擇要上傳的文件");
 4             }else{
 5                 CommonPerson.Base.LoadingPic.FullScreenShow();
 6                 $("#tkDiv").hide();
 7                  $("#tk1").hide();
 8                 $("#uploadForm").submit();    
 9             }
10         })

三、action處理

  1     /**
  2      * 人員信息導入
  3      * @param conId
  4      * @param code
  5      * @param request
  6      * @param response
  7      */
  8     @RequestMapping(params="method=insertUserInfo",method=RequestMethod.POST)
  9     public void insertUserInfo(Integer conId,String code,HttpServletRequest request,HttpServletResponse response){
 10         try {
 11             String msg = "";
 12             Integer state = 0;
 13             String fileUrl = "/files/excel/";
 14             HttpSession session  = this.getSession(request);
 15             Adminuser adminUser = session.getAttribute("centerAdminUser") == null?null:(Adminuser) session.getAttribute("centerAdminUser");
 16             if(adminUser == null){
 17                 try {
 18                     response.sendRedirect(request.getContextPath()+"/center/index.jsp");
 19                 } catch (Exception e) {
 20                     e.printStackTrace();
 21                 }
 22             }else{
 23                 MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
 24                 MultipartFile multipartFile = multipartRequest.getFile("files");
 25                 InputStream is = multipartFile.getInputStream();
 26                 if(is!=null){
 27                     Workbook wb = WorkbookFactory.create(is);
 28                     CellStyle style = wb.createCellStyle();
 29                     style.setFillForegroundColor(IndexedColors.RED.getIndex());
 30                     style.setFillPattern(CellStyle.SOLID_FOREGROUND);
 31                     List<UserInfo> userInfoList = new ArrayList<UserInfo>();
 32                     int rowCount = 0;
 33                     boolean temp = true;
 34                     try {
 35                         Sheet st = wb.getSheetAt(0);
 36                         int rowNum = st.getLastRowNum(); //獲取Excel最后一行索引，從零開始，所以獲取到的是表中最后一行行數減一
 37                         int colNum = st.getRow(0).getLastCellNum();//獲取Excel列數
 38                         for(int r=1;r<=rowNum;r++){//讀取每一行，第一行為標題，從第二行開始
 39                             rowCount = r;
 40                             Row row = st.getRow(r); 
 41                             UserInfo userInfo = new UserInfo();
