java.lang.NoClassDefFoundError：org / openxmlformats / schemas / spreadsheetml / x2006 / main / CTWorkbook $ Factory

我用例子： http ： //svn.apache.org/repos/asf/poi/trunk/src/examples/src/org/apache/poi/ss/examples/BusinessPlan.java

这是我的依赖列表：

  junit junit 4.12 test   org.apache.poi poi 3.15   org.apache.poi poi-ooxml 3.15   org.apache.poi poi-ooxml-schemas 3.15   com.github.jsqlparser jsqlparser 0.9.6     jsqlparser-snapshots  true  https://oss.sonatype.org/content/groups/public/

但有例外：

如何避免上述exception？

Answer 1

添加此依赖项：

  org.apache.poi ooxml-schemas 1.3  

（因为Eclipse IDE没有指向特定行缺失的依赖关系使得难以检测到问题）。

参考： http ： //poi.apache.org/faq.html#faq-N10025

Answer 2

系统找不到 poi-ooxml-schemas-xx.xx.jar ，

请将库添加到类路径中。
