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>

        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.poi/poi -->
        <dependency>
