Spring MVC AbstractView Java配置

Question

I am trying to implement Excel/PDF download using org.springframework.web.servlet.view.document. AbstractXlsxView .

My application is configured using org.springframework.web.servlet.support. AbstractAnnotationConfigDispatcherServletInitializer .

I have created my AbstractXlsxView with @Component and specified name to it.

@Component(VIEW_NAME_BASE_XLSX)
public class BaseXlsxView extends AbstractXlsxView {

public static final String VIEW_NAME_BASE_XLSX = "baseXlsxView";
public static final String MODEL_ATTRIBUTE_NAME_BASE_XLSX_VIEW_BEAN = "MODEL_ATTRIBUTE_NAME_BASE_XLSX_VIEW_BEAN";

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

    Sheet sheet = workbook.createSheet("Base Sheet");

    Row row = sheet.createRow(0);
    Cell cell = row.createCell(0, CellType.STRING);
    cell.setCellValue(new Date());

    response.setHeader("Content-Disposition",
            "attachment; filename=" + "BaseExcelDocument" + System.currentTimeMillis());

}

}

I am using the specified name as view name in ModelAndView returned by my controller.

@GetMapping(value = "/exportBaseXlsx")
public ModelAndView exportBaseXlsx(ModelMap modelMap, HttpServletRequest httpServletRequest) {
    return new ModelAndView(BaseXlsxView.VIEW_NAME_BASE_XLSX, BaseXlsxView.MODEL_ATTRIBUTE_NAME_BASE_XLSX_VIEW_BEAN,
            null);
}

This always throws 404 . It is trying to read a JSP file(as I have configured View resolver) instead of reading BaseXlsxView .

I have seen this way of implementing(not using views.xml with <bean id="myBeanId" class="myClassQualifiedName" > ) AbstractView is working in other applications but it is not working here.

我记得SpringMVC如果没有分配默认的view-adapter，也许默认的view-adapter返回jsp view。
