java - モデルSpring MVCから新しく作成したxlsファイルを保存する方法

Question

モデルから作成した xls ブックをハード ドライブに保存する際に問題があります。私はSpringsを使用してAbstractExcelViewおり、

protected void buildExcelDocument(Map<String, Object> model,
            HSSFWorkbook workbook, HttpServletRequest request,
            HttpServletResponse response) throws Exception

問題は、ウィンドウ ポップアップがユーザー画面に表示されず、ユーザーがファイルを保存する場所を選択して [保存] をクリックすることです。

     //This class makes convertation from Spring MVC model to excel document
        public class PagetoExcelConverter extends AbstractExcelView{

            List<FormDate> attributesList = null;   

            //Create massive of constants for making table header
            private final String[] HEADER_NAMES_MASSIVE = {"Name",  "Type",  "Date", "Description"};


            @SuppressWarnings("unchecked")
            @Override
            protected void buildExcelDocument(Map<String, Object> model,
                    HSSFWorkbook workbook, HttpServletRequest request,
                    HttpServletResponse response) throws Exception {

                        //Creating new instance of ArrayList for add model attributes to
                    attributesList = new ArrayList<FormDate>();

                        //Adding model attributes to ArrayList
                        attributesList.addAll((List<FormDate>)model.get("findAttributes"));

                //Creating sheet inside of book with given name 
                Sheet sheet = workbook.createSheet("Result");
                    sheet.autoSizeColumn(0);

                //Making first row as a header 
                Row headerRow = sheet.createRow(0);

                       //Creating  head for table by iterating over HEADER_NAMES_MASSIVE
                for(int i=0; i<HEADER_NAMES_MASSIVE.length; i++) {      

                    Cell headCell = headerRow.createCell(i); 
                    headCell.setCellValue(HEADER_NAMES_MASSIVE[i]);
                    headCell.setCellStyle(headCellstyle);   

                    }


                    int rowNumber=1;

                //Add data to table by iterating over and attributes
                for(int i=0; i<attributesList.size(); i++) {

                    Row dataRow = sheet.createRow(rowNumber);
                    Cell dataCell;

                    int cellNumber=0;

                        dataCell = dataRow.createCell(cellNumber);
                        dataCell.setCellValue(attributesList.get(i).getFormDescriptionList().get(i).getInstitutions().getNameOfInstitution());

                        cellNumber++;

                        dataCell = dataRow.createCell(cellNumber);
                        dataCell.setCellValue(attributesList.get(i).getFormDescriptionList().get(i).getInstitutionType().getTypeOfInstitution());
                        dataCell.setCellStyle(dataCellstyle);

                        cellNumber++;

                        dataCell.setCellValue(attributesList.get(i).getParticularDate());

                        cellNumber++;

                        dataCell = dataRow.createCell(cellNumber);
                        dataCell.setCellValue(attributesList.get(i).getFormDescriptionList().get(i).getDaySchedule());
                        dataCell.setCellStyle(dataCellstyle);

                        cellNumber++;

                        dataCell = dataRow.createCell(cellNumber);
                        dataCell.setCellValue(attributesList.get(i).getFormDescriptionList());

                        cellNumber++;

                        }

                attributesList = null;

            }

    }   

したがって、このコードを入れると:

FileOutputStream fos = new FileOutputStream("/home/vadim/Desktop/mybook.xls");
                workbook.write(fos);

保存する場所にファイルを保存します。しかし、ユーザーのために小さなウィンドウをポップアップさせたいと思います。

xlspage.(class)=edu.demidov.service.PagetoExcelConverter
