org/apache/poi/xssf/usermodel/XSSFWorkbook 的 NoClassDefFoundError

Question

我在论坛上进行了搜索，尽管有很多关于这个错误的问题，但他们都没有真正帮助我解决这个错误。

我收到此错误：

org.apache.cxf.interceptor.Fault: org/apache/poi/xssf/usermodel/XSSFWorkbook
    at org.apache.cxf.service.invoker.AbstractInvoker.createFault(AbstractInvoker.java:162)
    at [internal classes]
Caused by: java.lang.NoClassDefFoundError: org/apache/poi/xssf/usermodel/XSSFWorkbook
    at com.test.GetFromExcel.readXLSX(GetFromExcel.java:25)
    ... 1 more

[ERROR   ] SRVE0315E: Ocorreu uma exceção: java.lang.Throwable: org.apache.cxf.interceptor.Fault: org/apache/poi/xssf/usermodel/XSSFWorkbook
    at com.ibm.ws.webcontainer.webapp.WebApp.handleRequest(WebApp.java:4998)

我已经尝试删除 .m2 文件夹并再次下载依赖项，但仍然没有成功。 如图所示，我已经添加了 .jar 文件。

我可以看到错误抱怨的同一个类在org/apache/poi/xssf/usermodel/XSSFWorkbook 中的路径指示的位置列出。

如果我可以在我的项目中看到该类，我不清楚为什么会经常出现错误。

项目的 pom.xml 请求。

问题是我有 2 个使用这个库的其他项目，它们都没有让我像这样让 POI 库工作的头痛。我使用了之前在这些项目中使用的相同配置。

Answer 1

就我而言，我必须在我的 pom.xml 中添加以下依赖项

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>5.2.0</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>5.2.0</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>javax.xml.stream</groupId>
        <artifactId>stax-api</artifactId>
        <version>1.0-2</version>
    </dependency>
    <dependency>
        <groupId>commons-io</groupId>
        <artifactId>commons-io</artifactId>
        <version>2.11.0</version>
    </dependency>

所有这 4 个库都有准确的版本，包括 stax-api。需要注意的是，我使用的是 Maven。

希望它能对某人有所帮助（我确实花了几个小时来解决这个问题）。
