Word的模板导出(参考：https://easyexcel.opensource.alibaba.com/docs/current/quickstart/fill)

1. 创建有两个sheet的excel文件模板
   
   
2. 将模板文件放入resource\templates/doc下
3. 使用

    public void exportUavInfoExcel(HttpServletResponse response, CaseExportRPO caseExportRPO) throws IOException {response.setContentType("application/vnd.ms-excel");response.setCharacterEncoding("utf-8");response.setHeader("Content-Disposition", "attachment; filename=" + URLEncoder.encode("无人机情况汇报.xls", "utf-8"));// 获取数据库数据List<Object> caseList = baseMapper.getList();List<UavAreaExcel> typeList = exportStatisticsHandle(typeMap);// 获取模板String templateFileName = new ClassPathResource("templates/doc/uavInfoExcel.xls").getFile().getAbsolutePath();try (ExcelWriter excelWriter = EasyExcel.write(response.getOutputStream()).withTemplate(templateFileName).build()) {WriteSheet writeSheet = EasyExcel.writerSheet("按区域").build();excelWriter.fill(areaList, writeSheet);WriteSheet writeSheet1 = EasyExcel.writerSheet("按类型").build();excelWriter.fill(typeList, writeSheet1);// 写入时间Map<String, Object> map = new HashMap<String, Object>();map.put("timeRange", DateUtil.date(caseExportRPO.getStartTime()).toString(DatePattern.CHINESE_DATE_PATTERN) + " 至 " + DateUtil.date(caseExportRPO.getEndTime()).toString(DatePattern.CHINESE_DATE_PATTERN));excelWriter.fill(map, writeSheet);excelWriter.fill(map, writeSheet1);excelWriter.finish();}}
