贵州新手上路,请多包涵

这是一个javaweb项目,maven+tomcat环境,使用maven插件运行之后就会报这个错,以前按照正常步骤不会报错的,现在就报错了,不知道问题出在哪里,求大佬解决,有偿,感谢!

缺少依赖 org.springframework:spring-web:5.3.16

在pom.xml里加上

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>5.3.16.RELEASE</version>
</dependency>
