IDEA启动Springboot时，解决报错java.lang.NoClassDefFoundError: javax/servlet/Filter

如下所示，将spring-boot-starter-tomcat依赖中的<scope>provided</scope>注释掉

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