分析原因：
springboot项目配置文件pom.xm里,有关springboot的依赖tomcat有如下配置：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<scope>provided</scope>：表示产于编译运行，但不参与打包，打包由生产环境提供。
解决办法：
打开：Edit Configurations...，勾上Include dependencies with “Provided” scope,点击Apply,OK，然后重新编译运行即可。
