Question

我试图在不使用任何xml配置的情况下运行spring web mvc应用程序。我正在尝试将我的所有配置替换为春季4中列出的基于注释的配置

我遇到了一些例外情况，如

javax.servlet.ServletException: Failed to instantiate WebApplicationInitializer class

任何人都可以告诉我为什么我会遇到这样的问题以及如何解决这个问题

Answer 1

从pom.xml

中删除以下依赖项

<!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>3.0.2.RELEASE</version>
</dependency>

Spring web-mvc依赖本身足以下载spring-context和其他相关的jar

目前，您的spring-context依赖项与其他jar

发生冲突

Answer 2

参考：https://www.mkyong.com/spring/spring-error-classnotfoundexception-org-springframework-web-context-contextloaderlistener/

您需要加入spring-web.jar
