Inside your pom.xml you must remove the <scope>provided</scope> being like this:

The tag scope serves to define the scope of dependency if you put as provided means the container will provide the dependency, but since you are using Spring Boot without a container, there is no one to provide Tomcat

  • I pulled <Scope>provided</Scope> but did not work. No Sever was activated.

  • You have 2 Tomcat entries in your pom.xml, removed the duplicate

  • In the last Target file {pom.xml} folder. I changed and it didn’t work.

  • Do not change in target, will not take effect

  • Sorry, I am beginner using Spring boot and intelliJ. All changes I see are by POM via target folder. On videos and website.... Where you should then make POM changes?

  • Save the folder to the root target is automatically generated

  • [FIXING] The POM is after the Target folder.... And NOT inside the target folder...

  • How you are doing to run the application?

  • After q update the POM I go to Main and click on Run, according to the tutorials.

  • I believe Tomcat has not been downloaded by Maven, runs a mvn clean install, this way it will check and download dependencies

  • had done before.. refit, but did not activate

I had trouble with examples. Tomcat did not work in version 1.5.9.RELEASE:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
    <relativePath/> 
</parent>

Error 

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

Solution was to change the version to 1.5.0.RELEASE and it worked perfect.

Tomcat started on port(s): 8080 (http)
Started Demo01Application in 4.829 seconds (JVM running for 5.402)
