Answer 1

Your pom looks almost correct, but few things to note
No need to add dependency 'javax.servlet-api', it is available from 'spring-boot-starter-web'
And you probably you may be missing the 'spring-boot-maven-plugin', it is not compulsory but you may want that in your project. Where it provides some easy maven goals for you to run.
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
if your running eclipse you can generate your .classpath files just as usual
mvn eclipse:eclipse, once done your ide should look fine
then mvn spring-boot:run should set your application running
