2、解决方案参考

A part name shall not have a forward slash as the last character | 不支持：http://javax.xml.XMLConstants/property/accessExternalDTD · Issue #708 · Sayi/poi-tl · GitHub

或者做 POI版本升级

Java导入Excel文件时出现警告：A part name shall not have a forward slash as the last character-CSDN博客

3、本人采用的是在配置文件中忽略该报错，

配置如下：

在 application.properties 中添加

#忽略POI警告提高日志级别
logging.level.org.apache.poi.util.XMLHelper=ERROR
logging.level.org.apache.poi.openxml4j.opc.ZipPackage=ERROR

或者在 logback中添加配置-待验证
