解决方法：

将项目中pom.xml中依赖的  POI相关的版本升级到  3.17以上  【easyexcel版本  2.0.5】

我自己将POI版本升级到了4.1.0

报错：

java.lang.IncompatibleClassChangeError: class net.sf.cglib.core.DebuggingClassWriter has interface org.objectweb.asm.ClassVisitor as super class

和

Could not initialize class net.sf.cglib.beans.BeanMap$Generator

解决方法：

是因为项目中有cglib的jar包  和 asm的jar包冲突。解决掉jar包冲突即可。
