一，错误：java.lang.NoClassDefFoundError: org/apache/xmlbeans/XmlException

实现java代码导入导出Excel表格请参考导入excel代码（https://blog.csdn.net/laterstage/article/details/131713449?spm=1001.2014.3001.5501）

1. 错误原因：xmlbeans的jar

解决方式：引入jar包

1. 传统java项目，将xmlbeans-3.1.0.jar添加到依赖里面
2. maven项目引入下面依赖

    <dependency>
      <groupId>org.apache.xmlbeans</groupId>
      <artifactId>xmlbeans</artifactId>
      <version>3.1.0</version>
    </dependency>

如果以上问题没有解决，将下面pom依赖进行版本对照。

 <!-- 下面两个依赖是实现 导入excel的-->
    <dependency>
      <groupId>org.apache.poi</groupId>
      <artifactId>poi</artifactId>

    <dependency>

    </dependency>
