kaedah eksport js:

    $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);

            });

        };

Kaedah pemprosesan bahagian pelayan:

@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();
    }

Tetapi fail yang dimuat turun adalah seperti ini:

Konsol:

Jika saya menggunakan output excel jenis ini untuk mencari laluan, fail itu akan baik.

    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();
