Spring mvc 4 hello world示例抛出javax.servlet.ServletException：无法实例化WebApplicationInitializer类

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。我试图取代我的所有配置，以在春季上市的基于注解配置4

我面对像

添加

任何人都可以告诉我为什么我面临这样的问题，以及如何解决这个问题

Answer 1

从你的pom.xml中删除低于扶养

<!-- 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的web-MVC扶养本身足以下载弹簧上下文和其他相关的罐子

目前你的春天背景依赖与其他罐子混淆

按照此示例使用基于java的配置运行干净的spring mvc hello world example。

你可以找到更多春季指南official site`

Answer 2

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

您需要包括spring-web.jar
