经过分析，可能的原因
文件流是xls作为模板的，源码中在初始化excelType的时候，对inputStream做为模板的情况做处理未处理，默认成了xlsx。请大佬确认下这个需要修复吗？
目前解决方法，自己拿到inputStream之后判断是xls还是xlsx，在设置excelType。
ExcelWriter excelWriter = EasyExcel.write(outputStream).withTemplate(templateFile).excelType(ExcelTypeEnum.XLSX).build();

触发Bug的代码

    FileOutputStream outputStream = new FileOutputStream("test11.xls");
    ClassPathResource classPathResource = new ClassPathResource("template/test.xls");
    InputStream templateFile = classPathResource.getInputStream();
    ExcelWriter excelWriter = EasyExcel.write(outputStream).withTemplate(templateFile).build();

提示的异常或者没有达到的效果
