本文主要是介绍springboot+poi-tl根据模板导出word（含动态表格和图片），并将导出的文档压缩zip导出，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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
<dependency><groupId>com.deepoove</groupId><artifactId>poi-tl</artifactId><version>1.12.1</version>
</dependency>

  • 准备模板
    在这里插入图片描述
    文本标签用{{ }}，动态表格的字段标签用[]。

  • 代码实现
    3.1 控制器
