解决：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
将<scope>provided</scope>注释掉即可，当我们用maven install生成最终的构件包ProjectABC.war后，在其下的WEB-INF/lib中，会包含我们被标注为scope=compile的构件的jar包，而不会包含我们被标注为scope=provided的构件的jar包。就是说在provided的时候，部署的时候不会带上tomcat这个依赖，因为部署环境已经有了tomcat了。
