解决方法：
从maven仓库引入依赖，地址如下
https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml-schemas/3.17
除了引入easyexcel，还要引入poi，并且三个poi版本要一致。
poi，poi-ooxml，poi-ooxml-schemas 的版本号要一致
<!-- https://mvnrepository.com/artifact/com.alibaba/easyexcel --><dependency><groupId>com.alibaba</groupId><artifactId>easyexcel</artifactId><version>2.2.6</version></dependency><!-- https://mvnrepository.com/artifact/org.apache.poi/poi --><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>3.17</version></dependency><!-- https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml --><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>3.17</version></dependency><!-- https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml-schemas --><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml-schemas</artifactId><version>3.17</version></dependency>
