如何避免上述异常？
添加此依赖项：
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>ooxml-schemas</artifactId>
<version>1.3</version>
</dependency>
（因为Eclipse IDE没有指出缺少特定行的依赖关系使得难以检测到问题）。
系统找不到poi-ooxml-schemas-xx.xx.jar，
请将库添加到类路径中。
从这里添加jar并将其包含在类路径中：http://www.java2s.com/Code/Jar/p/Downloadpoiooxmlschemas39jar.htm
