angular.js - springMVC導出POI的excel，angularjs接收，但是excel打不開xlsx

Question

js導出方法：

    $scope.showYes = function () {

            var needFields = getTheNeedFields();

            $http.post("/aa.do?fields="+needFields, {responseType: 'arraybuffer'}).then(function (response) {

                var data = new Blob([response.data], {type: response.headers('Content-Type')});
                var filename = response.headers('Content-Disposition').split(';')[1].trim().substr('filename='.length);

                FileSaver.saveAs(data, filename);

            });

        };

服務端處理方法：

@RequestMapping("/aa")
    public void testExportDynamic(HttpServletResponse response) throws IOException {

        String fileName = System.currentTimeMillis()+"";
        response.setCharacterEncoding("UTF-8");
        response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet; charset=UTF-8");
        response.setHeader("Content-disposition", "attachment;filename=" + URLEncoder.encode(fileName, "utf-8")+ ".xlsx");
        OutputStream os = response.getOutputStream();


        Map map = new HashMap();
        String fields = request.getParameter("fields");
        map.put("fields", fields);
        //Map对象，带null的对象
        List<HashMap> result = userDao.loadDatasBySelectionFields(map);
        XSSFWorkbook workbook = MehtodApis.exportExcelFile(result, fields);

//        OutputStream os = new FileOutputStream("D:/export2007_" + System.currentTimeMillis() + ".xlsx");
        //
        workbook.write(os);
        os.close();
    }

但是下載的檔案是這樣的：

控制台：

如果我用這種輸出的excel到覺得路徑下，檔案是沒問題的。

    Map map = new HashMap();
        String fields = request.getParameter("fields");
        map.put("fields", fields);
        //Map对象，带null的对象
        List<HashMap> result = userDao.loadDatasBySelectionFields(map);
        XSSFWorkbook workbook = MehtodApis.exportExcelFile(result, fields);

        OutputStream os = new FileOutputStream("D:/export2007_" + System.currentTimeMillis() + ".xlsx");
        workbook.write(os);
        os.close();

神馬問題呢？怎麼處理好呢？

你斷點追蹤查看記憶體快照看一下你的資料有沒有問題和你的開啟的excel的版本一致不
