我在这两个包中遇到错误

导入 org.apache.poi.poifs.filesystem.*;

导入 org.apache.poi.hpsf.DocumentSummaryInformation;

类型 org.apache.poi.poifs.filesystem.POIFSFileSystem 无法解析。 它是从所需的 .class 文件间接引用的

我附上了我的 java 构建路径的快照...因为程序需要

poi-scratchpad-3.2-FINAL-20081019.jar

它在java构建路径中正确设置..那么为什么我会收到这样的错误..帮助..！！

Answer 1

找到它需要的解决方案 poi-3.7.jar

http://mvnrepository.com/artifact/org.apache.poi/poi/3.7

Answer 2

你有两个问题。 一个是您使用的是6 年前的Apache POI 3.2，从那时起已经修复了大量错误

第二个问题，您错过了一些 POI jar 及其依赖项。 有关详细信息，请参阅组件页面。 但是基本上，使用HWPF，你既需要的poi和poi-scratchpad在classpath罐

Answer 3

删除位于C:\\Users\\user\\.m2\\repository\\org\\apache\\poi整个已发布目录。

右键单击project > Maven然后Update project 。
