Можно ли внедрить класс обслуживания в классе abstractview?

Question

Я хотел бы использовать общую функцию (объект класса @service) в классе абстрактного представления, который приведен ниже. Я сделаю некоторые представления для своего проекта, поэтому я хотел бы сделать общую функцию для удобства в классе ExcelSharedService. Но это не работает хорошо. Не могли бы вы дать мне совет? пожалуйста ...

public class ExcelView extends AbstractXlsxView {

    // this part won't be injected when this class is initiated.
    @Inject
    private ExcelSharedService excelSharedService;


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

        // create sheet
        Sheet sheet = workbook.createSheet("Project");

        Row row = sheet.createRow(0);
        row.createCell(0).setCellValue("A");
        row.createCell(1).setCellValue("B");
        row.createCell(2).setCellValue("C");


       final String[] dataList = new String [] {"10", "20", "30"}; 
       CellRangeAddressList range = new CellRangeAddressList(1, 10000, 1, 1);

       // this is common function
       excelSharedService.setValidation(sheet, range, dataList);

    }
}

ExcelSharedService.java

@Service
public class ExcelSharedService {

    public void setValidation(Sheet sheet, CellRangeAddressList range, String[] dataList) {
            DataValidationHelper helper = sheet.getDataValidationHelper();
            DataValidationConstraint constraint = helper.createExplicitListConstraint(dataList);
            DataValidation validation = helper.createValidation(constraint, range);
            sheet.addValidationData(validation);
    }


    public void setMergedRegion(Sheet sheet, CellRangeAddress range, String value) {
        sheet.addMergedRegion(range);
        Row row = sheet.createRow(range.getFirstRow());
        Cell cell = row.createCell(range.getFirstColumn());
        cell.setCellValue(value);
    }
