该代码运行良好，但是当我 setUrl 在 Excel 中使用我的模板时，我收到此错误：

ApplicationObjectSupport 实例 [key.kotori.sms.utils.reports.StockReportsExcel：未命名] 不在 ApplicationContext 中运行。

public class StockReportsExcel extends AbstractExcelView {

    private StockReports reports;

    public StockReportsExcel(StockReports reports) {
        this.reports = reports;
        //super.setUrl("report/stock.xls");
    }

    @Override
    protected void buildExcelDocument(
        Map<String, Object> model,
        HSSFWorkbook workbook, 
        HttpServletRequest request,
        HttpServletResponse response) throws Exception {
            workbook.createSheet().createRow(0).createCell(0).setCellValue("kotori");       
            RequestEncoding.encoding(request, response, "test.xls");
            response.setContentType("application/vnd.ms-excel");
        }
    }

    Controller

    @RequestMapping("/excel.do")
    public View excel(Params params) {
        StockReports reports = this.stockReportService.reports(params);
        StockReportsExcel excel = new StockReportsExcel(reports);
        return excel;
    }

我没有在 applicationContext.xml 中设置任何 ViewResolver。appicationContext.xml 中我缺少什么吗？

这是 applicationContext.xml 文件。
