Answer 1

我认为您部署的战争不包含spring-web jar。

如果是maven项目，则在pom.xml中添加依赖项。

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version><!-- Add your version--></version>
</dependency>

或从 here下载jar。

如果您还有其他问题，请参考此问题： java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener
