springboot使用Easy Excel导出列表数据为Excel

Easy Excel官网：https://easyexcel.opensource.alibaba.com/docs/current/quickstart/write
主要记录一下引入时候的pom，直接引入会依赖冲突

解决方法：

<!-- 引入Easy Excel的依赖 --><dependency><groupId>com.alibaba</groupId><artifactId>easyexcel-core</artifactId><version>3.2.1</version><exclusions><exclusion><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId></exclusion><exclusion><groupId>org.apache.poi</groupId><artifactId>poi</artifactId></exclusion><exclusion><groupId>org.apache.poi</groupId><artifactId>poi-ooxml-schemas</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>3.16</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>3.16</version></dependency>
