我正在尝试ods使用Apache ODF Toolkit. java.lang.NoClassDefFoundError尝试使用以下代码加载电子表格时出现错误-

SpreadsheetDocument data = SpreadsheetDocument.loadDocument(file);

以下是错误跟踪 -

下面是项目结构，它显示了类路径- 日食截图

是否缺少任何依赖项？

看来您的代码找不到类： Caused by: java.lang.ClassNotFoundException: org.apache.xerces.dom.ElementNSImpl

来自ODF 工具包

注意：ODFDOM 需要 Apache Xerces。jar 文件 xercesImpl.jar 还必须存在于 odfxsltrunner.jar 文件旁边的文件夹 lib 中，或者它必须位于类路径中。ODF XSLT Runner NetBeans 项目在运行时类路径中包含对 xersesImpl.jar 的引用，必须在签出项目后对其进行调整。
