ClassNotFoundException org.odfclown.files.File

Question

我正在使用Maven和Spring MVC創建一個webapp。當使用Maven構建時會發生以下錯誤：

在我的構建路徑中，我已經導入了pdfclown.jars。是否可能發生此錯誤是因爲我在我的WebAppInitializer中使用了「標準」SpringDispatcher？

public class WebAppInitializer implements WebApplicationInitializer{ 

Controller 
    public void onStartup(ServletContext servletContext) throws ServletException { 
     AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext(); 
     appContext.register(AppContextConfig.class); 

     // Register and map the dispatcher servlet 
     ServletRegistration.Dynamic dispatcher = servletContext.addServlet("SpringDispatcher", 
       new DispatcherServlet(appContext)); 
     dispatcher.setLoadOnStartup(1); 
     dispatcher.addMapping("/"); 

     // UtF8 Charactor Filter. 
     FilterRegistration.Dynamic fr = servletContext.addFilter("encodingFilter", CharacterEncodingFilter.class); 

     fr.setInitParameter("encoding", "UTF-8"); 
     fr.setInitParameter("forceEncoding", "true"); 
     fr.addMappingForUrlPatterns(null, true, "/*"); 
    } 
}

你是否還增加了Maven的戰爭插件到您的插件（如果你不使用春天開機，如果你使用你需要添加自己的春天啓動的maven-plugin插件彈簧引導）？

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-war-plugin</artifactId> 
    <version>3.1.0</version> 
    <configuration> 
    <failOnMissingWebXml>false</failOnMissingWebXml> 
    </configuration> 
</plugin>
