一、问题来源

　　最近做一个导出路面感知数据到excel的功能，核心导出代码如下：

ServletOutputStream out = null;
        String result = null;
        try {
            if (CollectionUtils.isNotEmpty(list)) {
                //使用EasyPoi导出时，openjdk11字体不支持
                String fileName = "wifi_record_" + DateUtils.format(new Date(), DateUtils.DATE_TIME_FORMAT_YYYYMMDDHHMISS);
                ExportParams exportParams = new ExportParams("WIFI轨迹", "WIFI轨迹", ExcelType.XSSF);
                Workbook workbook = ExcelExportUtil.exportExcel(exportParams, WifiVo.class, list);
                out = response.getOutputStream();
                response.reset();
                response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8") + ".xlsx");
                response.setContentType("application/msexcel");
                workbook.write(out);
                out.flush();
                out.close();
            } else {
                result = "没有需要导出的数据！";
            }
        } catch (Exception e) {
            logger.error("WIFI轨迹导出失败！", e);
            result = "WIFI轨迹导出失败！";
        }

使用了easypoi中ExcelExportUtil工具类的exportExcel方法，本地windows开发环境使用的是jdk1.8，测试没有问题，发布linux环境之后报错如下：

简单来说就是字体不支持。

二、解决方法

　　放弃使用easypoi，自己使用POI类库编写导出功能，问题解决。

三、总结

　　网上搜索得知可以在linux上安装字体解决字体不支持的问题，但生产环境一般都是公安网环境，不便于后续发布现场，因此没有采用该方案。
