enable https for spring boot rest application - https

Question

How would I enable a spring boot application to be accessible when deployed with https?
I found a solution that says add the following to application-config.xml file
<security:http auto-config="true" create-session="stateless">
<security:intercept-url pattern="/**" access="ROLE_USER"
requires-channel="https" />
<security:http-basic />
</security:http>
I don't have that file except for web.xml;
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:web="http://java.sun.com/xml/ns/javaee"
xmlns="

Spring Boot support SSL configuration properties (in application.yaml|.properties)
server.port=8443
server.ssl.key-store=classpath:keystore.jks
server.ssl.key-store-password=secret
server.ssl.key-password=another-secret
You can do the same thing using TomcatEmbeddedServletContainerFactory.
