java.lang.NoClassDefFoundError:org/apache/poi/ss/usermodel/Workbook
JasonXie 发布于 2023-02-09 10:20我使用maven来管理我的Web项目依赖.我将apache poi依赖项添加到我的pom文件中.它在编译时不显示错误.但是当它运行时,它会在我的MainApplication()类中抛出RuntimeException.虽然它给出了java.lang.NoClassDefFoundError:org/apache/poi/ss/usermodel/Workbook
我有一个MainApplication类.
public class MainApplication extends Application {
private Set> classes = new HashSet>();
HashSet
}
以下是我添加的内容

Apache POI提供了一个组件页面,其中详细说明了项目的所有不同部分,您需要的jar以及您需要的Maven工件.如果你看那里你会看到以下内容:
|Component | Application type | Maven artifactId | Notes |Common SS | Excel XLS and XLSX | poi-ooxml | WorkbookFactory and friends all require poi-ooxml, not just core poi |
正如这清楚地表明,如果你想使用所有的常见org.apache.poi.ss类,你需要依赖poi-ooxml而不仅仅是依赖poi
其次,编译时间!=运行时间.只是因为一个jar被maven吸了下来并且可以编译,并不意味着它会在你的代码运行时出现.您还需要确保使用代码打包依赖项,或者确保它们在运行时位于类路径中.
你似乎(从堆栈跟踪)是编写一个Web应用程序,所以你需要确保所有的依赖性得到投入战争/WEB-INF/lib/,使他们在运行时在那里.
最后,POI 3.8 beta 3是一个非常奇怪的版本.你应该选择最新的稳定版(现在是3.9版),或者最新的版本(不是3.10 beta版).有关当前版本的详细信息,请参阅POI主页.
