springboot+poi-tl根据模板导出word(含动态表格和图片)

官网:http://deepoove.com/poi-tl/

参考网站:https://blog.csdn.net/M625387195/article/details/124855854

  • pom导入的maven依赖
java 复制代码
<dependency>
	<groupId>com.deepoove</groupId>
	<artifactId>poi-tl</artifactId>
	<version>1.12.1</version>
</dependency>
  • 准备模板

    文本标签用{``{ }},动态表格的字段标签用[]。

  • 代码实现
