Question

我尝试创建文档（excel / word），然后将其发送到浏览器进行下载。

该文件是在eclipse目录中创建的，但我没有收到保存/下载文件的对话框。相反，我有像＃34; ��RootEntry��Workbook��A��\phpB�a=� = H：＃8X @＆＃34; 1Arial1Arial1Arial1Arial＆＃34; $＆＃34;＃，## 0 _）;（＆＃34; $＆＃34;＃，## 0）＆＃34; $＆＃34;＃，## 0 _）; [红色] 0）; （*＆＃34; - ＆＃34; ）; （@ ）5）0 _（＆＃34; $＆＃34; *＃，## 0 _）; （＆＃34;�� `�bSheet0��一些文字�D��Xd��MbP？ * +��％�� ＆＃34; d ,,�？�？U��＆＃34;＆gt;�@��＆＃34;

这是（excel）的代码：

public void exportResults_EXCEL(ActionRequest actionRequest, ActionResponse actionResponse)throws IOException,PortletException{


        HSSFWorkbook wb = new HSSFWorkbook();
        HSSFSheet sheet = wb.createSheet();
        HSSFRow row = sheet.createRow(0);
        HSSFCell cell = row.createCell(0);
        cell.setCellValue("Some text");

        // write it as an excel attachment
        ByteArrayOutputStream outByteStream = new ByteArrayOutputStream();
        wb.write(outByteStream);

        ByteArrayInputStream excelStream = new ByteArrayInputStream(outByteStream.toByteArray());
        byte [] outArray = outByteStream.toByteArray();

        HttpServletRequest request = PortalUtil.getHttpServletRequest(actionRequest);
        HttpServletResponse response = PortalUtil.getHttpServletResponse(actionResponse);

        response.setContentType("application/vnd.ms-excel");
        response.setHeader("Content-Disposition", "attachment;filename=something.xls");
        response.setContentLength(outArray.length);

ServletResponseUtil.sendFile(request, response, "something.xls" ,outArray, ContentTypes.APPLICATION_VND_MS_EXCEL);

        FileOutputStream output = new FileOutputStream(new File("something.xls"));
        ServletOutputStream out = response.getOutputStream();

        wb.write(output);
        output.flush();
        output.close();
}

P.S！我使用eclipse，liferay，poi

Answer 1

对于任何挣扎于此的人，它与liferay有关，因为我没有在actionURL中指定windows状态，因为我正在使用弹出窗口。

   <portlet:actionURL var="exportURL" name="exportEXCEL" windowState="<%= LiferayWindowState.POP_UP.toString() %>">

并在java中将文件发送到浏览器下载：

    ByteArrayOutputStream outByteStream = new ByteArrayOutputStream();
    wb.write(outByteStream);

    byte [] outArray = outByteStream.toByteArray();
    HttpServletRequest request = PortalUtil.getHttpServletRequest(actionRequest);
   HttpServletResponse response = PortalUtil.getHttpServletResponse(actionResponse);

    ServletResponseUtil.sendFile(request, response, "result.xls" ,outArray, ContentTypes.APPLICATION_VND_MS_EXCEL);

与Liferay的EXCEL / WORD POI
