日常的開發中，需要將word 等各類文章信息轉換成格式化語言，因此需要使用各類語言將word 轉換成Markdown
1、引入 jar包
<dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>5.2.3</version></dependency>2、使用以下代碼進行編寫
package com.nd.ai.test.service.utils;import com.alibaba.fastjson.JSONObject;

}
獲得信息
{
"fileImagePathList":["文件中圖片路徑1","文件中圖片路徑2"],
"markdownContent": "markdwon 信息",
"mdPath": "markdown文件地址"
}運行上方的程序將會得到
1、解析文件中所有圖片信息，保存到下方的地址
2、將word 文檔轉換成markdown
3、獲取markdown 文件
