Answer 1

It doesn't require for a standalone jar application: providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'. Starter-web includes one
When you've declared this dependency you said you build to exclude tomcat for a standalone run. This means - no servlet library inside
If you deploy this app somewhere, then just exclude tomcat from starter-web, like this:
compile('org.springframework.boot:spring-boot-starter-web'){
exclude module: "spring-boot-starter-tomcat"
}
