• java实现导入excel功能


    实现功能:

      1、Excel模板下载

      2、导入excel

    一、jsp效果和代码

     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="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>点击下载人员模板</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="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="720px;border- 0.3px;margin-left:-10px;">
    14                         <button id="tiJiao" type="button" class="czbtn" style="100px;font-size: 16px;">导入</button>
    15                     </td>
    16                 </tr>
    17                 </table>
    18             </form>
    View Code

    二、js代码

     1 $("#tiJiao").click(function(){
     2             if($("#files").val() == ""){
     3                 alert("请选择要上传的文件");
     4             }else{
     5                 CommonPerson.Base.LoadingPic.FullScreenShow();
     6                 $("#tkDiv").hide();
     7                  $("#tk1").hide();
     8                 $("#uploadForm").submit();    
     9             }
    10         })
    View Code

    三、action处理

      1     /**
      2      * 人员信息导入
      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 {

     36                         int rowNum = st.getLastRowNum(); //获取Excel最后一行索引,从零开始,所以获取到的是表中最后一行行数减一
     37                         int colNum = st.getRow(0).getLastCellNum();//获取Excel列数

     41                             UserInfo userInfo = new UserInfo();
     42                             for(int l=0;l<colNum;l++){//读取每一行的每一列
     43                                 Cell cell = row.getCell(l);
     44                                 if(cell != null){

     48                                     if(cell != null && !"".equals(cell.toString().trim())){
     49                                         System.out.print(cell + "	");
