Java使用word模板导出word

1.创建一个空的springboot工程，引入jar包

<dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>3.17</version>
</dependency>
<dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>3.17</version>
</dependency>

maven工程只需引入2个jar，系统会自动添加其他相关jar包
