IDEA2019 Spring boot Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.

错误：Caused by: org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.

在 pom.xml文件中注释掉scope

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <!--<scope>provided</scope>-->
</dependency>

IDEA注释掉之后记得要使用Maven进行import Changes然后运行才能生效
