官方model网址：http://svn.apache.org/repos/asf/poi/trunk/src/examples/src/org/apache/poi/xwpf/usermodel/examples/。

需要jar包：

<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>

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

根據官方model可以做很多事情，一下是我改變的例子，可以直接運行：
