모델에서 새로 생성 된 xls 파일을 저장하는 방법 Spring MVC

Question

모델에서 생성 한 xls 책을 하드 드라이브에 저장하는 데 문제가 있습니다. 내가 문제 스프링스 AbstractExcelView 및

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

를 사용하고있어 내가 파일을 저장하고 저장을 클릭 할 수있는 장소를 선택 사용자, 사용자 화면에 팝업 창을 위해 나는 방법을 만들 수 없다는 것입니다.

 //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; 

      } 

    } 

그래서, 나는이 코드 조각을 넣으면 :

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

그것은 내가 그것을 저장 포인트 파일을 저장합니다. 그러나 나는 사용자를 위해 작은 창을 팝업하고 싶습니다. 웹 애플리케이션/WEB-INF/클래스에서

내 view.properties : 서블릿 컨텍스트에서

#This view property triggered from org.springframework.web.servlet.view.ResourceBundleViewResolver for xls converting 
#Here is xlspage is name of the jsp page, is tied in with (class) with do converting model to xls 
xlspage.(class)=edu.demidov.service.PagetoExcelConverter 

내 ViewResolvers를 선언 : 당신은 엑셀 뷰에 대한 XmlViewResolver을 작성해야

<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/classes directory. Goes first --> 
    <beans:bean id="xlsviewResolver" class="org.springframework.web.servlet.view.ResourceBundleViewResolver"> 
    <beans:property name="order" value="1" /> 
    <beans:property name="basename" value="views"/> 
    </beans:bean> 

    <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory --> 
    <beans:bean id="jspviewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" > 
     <beans:property name="prefix" value="/WEB-INF/views/" /> 
     <beans:property name="suffix" value=".jsp" /> 
    </beans:bean> 

Answer 1

:

<bean id="PagetoExcelConverter" class="edu.demidov.service.PagetoExcelConverter" /> 

컨트롤러에서 ModelAndView :

을 반환해야합니다.

return new ModelAndView("PagetoExcelConverter", "excelModel", excelModel); 

excelModel은 map입니다. 자세한 내용은 tutorial을 참조하십시오.
