我有一个写出电子表格的 Tomcat 应用程序，它使用以下 JAR 文件：

  • poi-3.16.jar
  • poi-ooxml-3.16.jar
  • poi-ooxml-schemas-3.16.jar

我看到有一个 4.0.1 版本的 poi，在查看https://poi.apache.org/components/时，我认为我已经设置了先决条件，但是运行时出现异常：

25-Mar-2019 22:33:37.117 SEVERE [http-nio-8181-exec-10] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [xxx.ApplicationConfig] in context with path [/DataLoaderREST] threw exception [org.glassfish.jersey.server.ContainerException: java.lang.ExceptionInInitializerError] with root cause
 java.lang.RuntimeException: Uncompilable source code - cannot find symbol
  symbol:   class POIXMLDocument
  location: package org.apache.poi

更新：

显然，当我构建出现上述错误的 .WAR 文件时，NetBeans 似乎找到了旧的 3.16 jar 文件并编译了我的代码，但我在服务器上没有 3.16 jar 文件。现在我已经在 NetBeans 中进行了清理，我无法在 NetBeans 中进行编译。

错误：

--- maven-compiler-plugin:2.3.2:compile (default-compile) @ DataModules ---
Compiling 44 source files to C:\xxx\xxx\10 Software\Java\LoaderFramework\DataModules\target\classes
-------------------------------------------------------------
COMPILATION ERROR : 
-------------------------------------------------------------
com/xxx/billing/loader/parser/ExcelParser.java:[36,21] error: cannot find symbol

ExcelParser.jara 第 36 行是：

import org.apache.poi.POIXMLDocument;

这是我的 pom.xml，引用了 4.0.1 jar：

我已经检查了我的 NetBeans .m2 存储库，并且在C:\Users\mstewart\.m2\repository\org\apache\poi\poi\andpoi\ooxml和 and中有 3.16 和 4.0.1 目录poi\ooxml-schemas

我盯着编译器错误

import org.apache.poi.POIXMLDocument;

好几天了，只是注意到它缺少ooxml包裹的一部分；将其更改为

import org.apache.poi.ooxml.POIXMLDocument;

一切都很好。感谢阿克塞尔的链接；这帮助我最终找到了问题。
