Question

我需要导出一个xls文件。我使用Spring MVC和Apache POI。我不能下载xls文件....按照代码更好地解决。

我在javascript中使用此方法来调用控制器

this.exportExcel = function() {
    $.get("exportar", function(data){

    });
};

在我的控制器中，我将该类调用为builder xls

@RequestMapping(value = "/exportar")
public ModelAndView exportExcel(HttpServletResponse response) {
    return new ModelAndView("excelView", "listForExcel", listDemanda);
}

使用构建器XLS

的类

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

    List<TB_Demanda> listForExcel = (List<TB_Demanda>)model.get("listForExcel");

    System.out.println("entrou no excel builder");

    HSSFSheet sheet = workbook.createSheet("Aba 1");

    Row row = sheet.createRow(0);
    Cell cell;

    cell = row.createCell(0);
    cell.setCellValue("Código");

    cell = row.createCell(1);
    cell.setCellValue("Descrição");

    cell = row.createCell(2);
    cell.setCellValue("Data de Inclusão");

    cell = row.createCell(3);
    cell.setCellValue("Data Prevista para Entrega");

    cell = row.createCell(4);
    cell.setCellValue("Situação");

    cell = row.createCell(5);
    cell.setCellValue("Fase");

    int numCelula = 0;
    int numLinha = 1;

    for(TB_Demanda d : listForExcel) {
        row = sheet.createRow(numLinha);

        cell = row.createCell(numCelula++);
        cell.setCellValue(d.getCodigoDemanda());

        cell = row.createCell(numCelula++);
        cell.setCellValue(d.getDescDemanda());

        cell = row.createCell(numCelula++);
        cell.setCellValue(Utils.dataFormatoPadrao(d.getDtInclusaoDemanda()));

        cell = row.createCell(numCelula++);
        cell.setCellValue(Utils.dataFormatoPadrao(d.getDtPrevistaEntrega()));

        cell = row.createCell(numCelula++);
        cell.setCellValue(d.getDescSituacaoEntrega());

        cell = row.createCell(numCelula++);
        cell.setCellValue(d.getDescTipoFase());

        numCelula = 0;
        numLinha++;
    }
}

所以当我点击按钮导出时我无法进行下载。谁知道发生了什么？
