IDEA配置的spring boot项目的tomcat依赖为

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-tomcatartifactId>
            <scope>providedscope>
        dependency>

provided的含义?
maven中的scope

后面试了一下，把范围标识 provided 改成 compile ,发现就可以运行了，所以就是 Run Application时，IDEA未加载 provided 范围的依赖包，导致启动时报错（eclipse里面好像默认会加载，所以在那边是能正确运行的）

解决方式 Run ->Edit Configurations

参考说明：For the Spring Boot applications, the Include dependencies with “Provided” scope option is enabled by default. （按理说对于Spring-Boot项目默认是启用的，我这默认没启用所以报错）
