portlet / webapp中是否存在aspose单元格？

Question

我正在写一个网站，允许用户上传excel文件，然后将内容转换为MYSQL语句。

编码：

public void convertToSQL(ActionRequest actionRequest,ActionResponse actionResponse) throws Exception 
    {
        Connection conn = null;
        PreparedStatement pstmt = null;
        try {
        conn = this.getDbConnection(conn);
        conn.setAutoCommit(false);
        UploadPortletRequest uploadPortletRequest = PortalUtil.getUploadPortletRequest(actionRequest); 
        String uploadedTemplateId = uploadPortletRequest.getParameter("templateId");
        System.out.println("uploadedTemplateId:"+uploadedTemplateId);

        File uploadedFile = uploadPortletRequest.getFile("uploadedFile", true); 
        System.out.println("uploadedDocument:" + uploadedFile.getName());
        String test2="insert akpi_db.dbo.tpl_estimate_gdh (hosp) values ('testgetfile')";
        pstmt = conn.prepareCall(test2);
        pstmt.executeUpdate();

        Workbook wb1 = new Workbook(uploadedFile.getAbsolutePath());
        String test1="insert akpi_db.dbo.tpl_estimate_gdh (hosp) values ('testgetpath')";
        pstmt = conn.prepareCall(test1);
        pstmt.executeUpdate();
        int pageNum = wb1.getWorksheets().getCount();
        test1="insert akpi_db.dbo.tpl_estimate_gdh (hosp) values ('getpageNum')";
        pstmt = conn.prepareCall(test1);
        pstmt.executeUpdate();
        for (int i=0;i< pageNum;i++){
            Worksheet ws1 = wb1.getWorksheets().get(i);
            Cells cells1 = ws1.getCells();
            int row = getPrintAreaMaxRow(ws1);
            int col = getPrintAreaMaxColumn(ws1);
            final String as_at_date_id = "convert(varchar(8), getdate(), 112)";
            final String process_dtm = "getdate()";


            for (int j=6;j<row;j++){
                for (int k=0;k<col;k=k+2){
                    Cell fin_year_cell = cells1.get(1,1);
                    Cell hosp_cell = cells1.get(j,0);
                    String[] parts = fin_year_cell.getStringValue().split("/");
                    int fin_year = Integer.parseInt(parts[0]);
                    String hosp = hosp_cell.getStringValue().replaceAll("\\s+", "");


                    Cell gdh_places_cell = cells1.get(j,k);
                    Cell gdh_attns_cell = cells1.get(j,k+1);


                    String gdh_places = gdh_places_cell.getStringValue();
                    String gdh_attns = gdh_attns_cell.getStringValue();


                    Cell cal_cell = cells1.get(4,k);
                    String[] date = cal_cell.getStringValue().split("-"); //date[1] = cal_year
                    int cal_month = 0,fin_month=0;
                if (date[0] == "Jan"){
                        fin_month=10;
                        cal_month=1;
                }else if (date[0] == "Feb"){
                        fin_month=11;
                        cal_month=2;
                }else if (date[0] == "Mar"){
                        fin_month=12;
                        cal_month=3;
                }else if (date[0] == "Apr"){

                }else if (date[0] == "May"){

                }else if (date[0] == "Jun"){
                        fin_month=3;
                        cal_month=6;
                }else if (date[0] == "Jul"){
                        fin_month=4;
                        cal_month=7;
                }else if (date[0] == "Aug"){
                        fin_month=5;
                        cal_month=8;
                }else if (date[0] == "Sep"){
                        fin_month=6;
                        cal_month=9;
                }else if (date[0] == "Oct"){
                        fin_month=7;
                        cal_month=10;
                }else if (date[0] == "Nov"){
                        fin_month=8;
                        cal_month=11;
                }else if (date[0] == "Dec"){
                        fin_month=9;
                        cal_month=12;
                }

                   if ( cal_month!=0 && fin_month!=0){

                    String sql ="insert into akpi_db.dbo.tpl_estimate_gdh (hosp,cal_year,cal_month,fin_year,fin_month,gdh_place,gdh_attn,as_at_date_id,process_dtm)"+
                            "VALUES(?,?,?,?,?,?,?,?,?)";
                    String test="insert akpi_db.dbo.tpl_estimate_gdh (hosp) values ('testconvert')";
                    pstmt = conn.prepareCall(test);
/*                  pstmt.setString(1, hosp);
                    pstmt.setString(2, date[1]);
                    pstmt.setInt(3, cal_month);
                    pstmt.setInt(4, fin_year);
                    pstmt.setInt(5, fin_month);
                    pstmt.setString(6, gdh_places);
                    pstmt.setString(7, gdh_attns);
                    pstmt.setString(8, as_at_date_id);
                    pstmt.setString(9, process_dtm);*/

                    pstmt.executeUpdate();

                   }
            }
        }

        }
        pstmt.close();
        conn.commit();
        }catch(Exception e){
            e.printStackTrace();
        }finally {
             if (conn != null) {
                 try {
                        conn.setAutoCommit(true);
                        conn.close();
                } catch(SQLException excep) {
                       System.out.println("Connection cannot be closed.");
                }
             }
         }

    }

但是我发现我的代码不起作用，并且在尝试调试之后。 错误发生在这一行

int pageNum = wb1.getWorksheets().getCount();

问题是，在日志文件中，它没有抛出任何异常。 在用于测试的数据库中，它仅插入“ testgetfile”和“ testgetpath”，“ getpageNum”和“ testconvert”尚未插入数据库，因此我猜错误在上述句子中发生。

即使我尝试将多页或单页excel上传到Web，但它们都不起作用

但是这句话错了吗？ 编译器和服务器不会给我任何错误异常。

您能否与示例文件共享一个示例演示应用程序（可运行）。 我们将重现该问题，并在分析后提供反馈。
