猜测原因:(因为试了好几次了)

第一:

项目中由于pom.xml 的原因

没有

<dependency>

   <groupId>org.springframework.boot</groupId>

   <artifactId>spring-boot-starter-web</artifactId>

</dependency>

第二:

项目中可能由于Maven仓库的问题

我们加入tomcat的依赖

<dependency>

  <groupId>org.springframework.boot</groupId>

  <artifactId>spring-boot-starter-tomcat</artifactId>

  <scope>provided</scope>

</dependency>

第三:(也是运行成功的)

清理Maven的org 下 apache 文件夹,让Maven重新下载jar包

或者运行Maven命令,清理jar包

dependency:purge-local-repository
