java.lang.NoSuchMethodError: org.apache.poi.ss.usermodel.Cell.getCellType

同理：参考文章java.lang.IncompatibleClassChangeError: Found interface org.apache.poi.util.POILogger, but class was expected的解决方案之一

找到pom依赖中poi相关jar包版本，如

<dependency>
	<groupId>org.apache.poigroupId>
	<artifactId>poiartifactId>
	<version>3.17version>
dependency>

改为

<dependency>
	<groupId>org.apache.poigroupId>
	<artifactId>poiartifactId>
	<version>4.1.2version>
dependency>

完成！

问题查找方法：我们可以在pom依赖文件中的任意位置，右击选择Diagrams查看该模块的jar包依赖图进行问题分析

将图放大进行查看，找到依赖的源头（可能在项目的其他模块中），对冲突（红线标注）的jar进行处理——修改版本或者注释、删掉等
