POI 在Word中添加图章--浮于文字或在文字下方的图片（文字环绕）

1、添加依赖

<dependency>
	     <groupId>org.apache.poi</groupId>
	     <artifactId>poi-ooxml</artifactId>
	     <version>3.15</version>
</dependency>
<dependency>
	    <groupId>org.apache.poi</groupId>
	    <artifactId>poi-scratchpad</artifactId>
	    <version>3.15</version>
</dependency>

2、工具类
