Apache POI生成的pptx在office中打不开 兼容问题 wps中可以打卡问题 POI显示兼容问题

项目场景：

在java服务中使用了apache.poi后生成的pptx在wps中打开是没有问题，但在office中打开显示如下XXX内容问题，修复（R）等问题

我是用的依赖版本如下

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>5.2.3</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>5.2.3</version>
</dependency>

原因分析：

提示：可以把适配的解压看里面的slide，有部分格式是不同的，为此直接用下面的服务层即可，我使用的纯流方式，没有文件夹，输入输出都是可以让AI帮你修改下的，主流程逻辑不要动

解决方案：

这里换上你自己的项目的Executor或者默认的即可，调用xmlFormate方法即可
