java使用poi给word添加多个水印

限制高版本的docx

一、解决poi给word添加水印遇到的问题：

1、遇到有页眉的word时水印添加失败

2、水印最底层被图片表格覆盖

二、解决思路：

1、把原来的页眉删除或者覆盖

2、水印只能在底层，那么我给它加多个水印

三、结果：

四、代码

maven配置

        <dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>4.1.2</version></dependency><!--2007 docx文件读取，需要导入poi-ooxml--><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>4.1.2</version></dependency>

代码工具类

}

创建 org.apache.poi.xwpf.model 包，重写 XWPFHeaderFooterPolicy 类如下：
