听起来像是你没有正确的依赖于你的项目。 POIXMLTypeLoader自带POI 3.14-β1和OOXML-模式：1.3参考该class.You有以下几种选择，你可以在你的项目中添加这种依赖性任何：

• 使用POI 3.14β1的

  <dependency> 
      <groupId>org.apache.poi</groupId> 
      <artifactId>poi</artifactId> 
      <version>3.14</version> 
  </dependency> 
  

• 使用OOXML图式1.2

  <dependency> 
  <groupId>org.apache.poi</groupId> 
  <artifactId>poi-ooxml-schemas</artifactId> 
  <version>3.14</version> 
  </dependency>
