java应用中数据导出工具，目前只支持excel,后续会支持其他格式

附上使用例子：

 @RequestMapping("exportExcel")
public void exportExcel(HttpServletRequest request, HttpServletResponse response) {
    File file = null;
    FileInputStream inputStream = null;
    try {
        String fileName = buildFileName();

        response.setContentType("application/vnd.ms-excel");
        response.setHeader("Content-disposition", "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8"));
        OutputStream outputStream = response.getOutputStream();

        List<ExportDataToExcelModel> dataToExcelList = cinemaFeeRuleBiz.queryExportDataToExcelData();
        file = ExportDataToExcel.<ExportDataToExcelModel>export(dataToExcelList, fileName);
        inputStream = new FileInputStream(file);
        byte[] buff = new byte[1024];
        int index = 0;
        while ((index = inputStream.read(buff, 0, 1024)) > 0) {
            outputStream.write(buff, 0, index);
        }
        outputStream.flush();
        outputStream.close();

    } catch (Exception e) {
        logger.warn("exportExcel error.",e);
    } finally {
        FileUtils.deleteQuietly(file);
        IOUtils.closeQuietly(inputStream);
    }
}
