我正在尝试使用简单的Spring MVC项目,但我在Tom Cat上有例外
HTTP状态500 - servlet mvc-dispatcher的Servlet.init()抛出异常
输入例外报告
用于servlet mvc-dispatcher的消息Servlet.init()抛出异常
说明服务器遇到内部错误,导致无法完成此请求。
例外

发生错误,因为找不到mvc-dispatcher-servlet.xml
文件。您需要在mvc-dispatcher-servlet.xml
文件夹中创建WEB-INF
文件。
对于前你可以参考以下链接: -

pls添加spring-core依赖项并可以使其适应
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>{your version}</version>
</dependency>
