文档模板
有时候我们希望 word 中有一个模板，然后在这个模板的基础上进行生成。
我们可以去解析 word 的基本信息，然后对其中的内容进行替换。
示例代码
maven 导入
<!-- poi Excel、Word操作-->
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.9</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.7</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml-schemas</artifactId>
<version>3.9</version>
</dependency>
自定义 XWPFDocument
其实就是对基础的 XWPFDocument 进行扩展，支持图片的生成。
这个例子图片是基于 xml 的原理生成的，不是很建议这么做。

定义 word 模板工具类
对 word 模板的文本，表格中的信息。
如果是 ${XXXX}，则进行替换。

其中 templatePath 对应的文件，就是一个包含 ${author} 信息文件，这里直接是匹配替换。
生成之后的文件，${author} 就会被替换成为 binbin.hou。其他更多字段信息，也是同理。
