Question

我有一个Tomcat应用程序，可以写出电子表格，并且正在使用以下JAR文件：

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

我看到有poi的4.0.1版本，并且看着https://poi.apache.org/components/，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，当我构建给出上述错误的.WAR文件时，看起来NetBeans找到了旧的3.16 jar文件并编译了我的代码，但是我在服务器上没有3.16 jar文件。现在，我已经在NetBeans中完成了清理工作，现在无法在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罐子：

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

Answer 1

我盯着编译器错误

import org.apache.poi.POIXMLDocument;

好几天了，只是注意到它缺少软件包的ooxml部分；将其更改为

import org.apache.poi.ooxml.POIXMLDocument;

一切都很好。感谢Axel提供的链接；最终帮助我找到了问题。

4.0.1版中的org.apache.poi.POIXMLDocument类在哪里？
