导出Word文档

framework摸版方式

导入依赖

用到一个工具包，你也可用自己的代码实现

<!--framework-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-freemarker</artifactId>
    <version>last</version>
</dependency>

<!--hutool工具包-->
<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>${hutool.version}</version>
