项目场景：
公司的一个小的报表填报和导出的演示demo。项目采用springboot搭建，导出功能使用alibaba的EasyExcel工具包进行excel报表模版读取并填充后导出，使用过程中出现两个名称为“Create workbook failure”的错误。
问题描述
1. 读取resource目录的数据的时候，出现“: Unexpected record signature: 0XEFBDBFEF”问题，日志如下：

1.1. 解决方式
出现该问题疑似是模版文件在编译打包后发生变化，系统加载的模版资源文件与原文件不一致。添加如下maven-build插件，该问题消失。
<!-- 避免font文件的二进制文件格式压缩破坏 -->
<plugin>
<groupId></groupId>
<artifactId>maven-resources-plugin</artifactId>
<configuration>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
<nonFilteredFileExtension>xlsx</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
2. 读取文件没问题后，又出现另外一个问题，“The supplied data appears to be in the OLE2 Format. You are calling the part of POI that deals with OOXML (Office Open XML) Documents. You need to call a different part of POI to process this data (eg HSSF instead of XSSF)”，日志如下：

2.1. 解决方式
从日志可以明显看出，资源模版读取成功后，使用easyexcel获取模版中的sheet页时出现问题，没有明确的识别excel文件的版本。从easyexcel文档中找到了类型参数设置方法(excelType.(ExcelTypeEnum))，配置相应的模版文件版本后该问题消失。代码如下：
try (InputStream inputStream = classPathResource.getInputStream();
ServletOutputStream outputStream = response.getOutputStream()) {
EasyExcel.write(outputStream)
//设置模版类型
.excelType(ExcelTypeEnum.XLS)
.withTemplate(inputStream)
.sheet()
.doFill(resultXls);
} catch (Exception e) {
e.printStackTrace();
}
附上下载方法代码：
@Override
public void exportXls(TongtechResultDto tongtechResult, HttpServletResponse response) throws Exception {
//查询出来的对象
List<String> ids = Lists.newArrayList();
TongtechResultXls resultXls = getExcelData(tongtechResult, ids);
// 配置响应流，
response.setContentType("application/-excel");
response.setCharacterEncoding("utf-8");
// 这里可以防止中文乱码 当然和easyexcel没有关系
String fileName = URLEncoder.encode("*******统计表", "UTF-8");
response.setHeader("Content-disposition", "attachment;filename=" + fileName + ".xls");
//获取模板
ClassPathResource classPathResource = new ClassPathResource("/templates/*******统计表.xls");
try (InputStream inputStream = classPathResource.getInputStream();
ServletOutputStream outputStream = response.getOutputStream()) {
EasyExcel.write(outputStream)
//设置模版类型
.excelType(ExcelTypeEnum.XLS)
.withTemplate(inputStream)
.sheet()
.doFill(resultXls);
} catch (Exception e) {
e.printStackTrace();
}
}
