在web.xml中执行maven Spring web mvc时出现异常

Question

在使用spring mvc和maven依赖关系管理时运行代码后获得以下异常。有人可以帮忙吗？检查下面链接的答案

java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext

Spring security configuration: IllegalStateException: BeanFactory not initialized or already closed

BeanFactory not initialized or already closed - call 'refresh' before

BeanFactory not initialized or already closed - call 'refresh' before accessing beans

但没有任何效果。

已经执行/运行应用程序而不使用maven通过将jar添加到lib文件夹它工作正常，但是当使用maven时它会抛出此异常。 MI检查了部署程序集的maven依赖关系，它们存在于该位置。我是maven的初学者。如有任何建议请告诉我。

Answer 1

这类错误的最常见原因是您通过Maven直接或通过依赖项导入相同类的多个版本，因此在运行时从类路径中选择了错误的版本。 或者您导入了Tomcat容器已经提供的一些servlet类。 尝试从依赖项中排除一些工件。或者这里是我使用的servlet依赖项，它与你的配置类似，没有任何问题。

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        <scope>provided</scope>
    </dependency>
