即使我的控制器方法中没有错误,我也无法从浏览器下载excel文件.

 @RequestMapping(value = "/getExcelFile", method = RequestMethod.GET, produces="application/json")
public @ResponseBody HttpEntity<byte[]> getUserDetailsExcelFile(@RequestParam Long id) {
    try {
            byte[] wb =  ExcelReportView.buildExcelDocument(data);
            HttpHeaders header = new HttpHeaders();
            header.setContentType(new MediaType("application", "vnd.openxmlformats-officedocument.spreadsheetml.sheet"));
            header.set("Content-Disposition",
                           "attachment; filename=test.xls");
            header.setContentLength(wb.length);
            return new HttpEntity<byte[]>(wb, header);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return null;
}

我收到了来自firebug的信息请求.
