I have followed the article https://docs.spring.io/spring-security/site/docs/4.0.2.RELEASE/reference/html/headers.html#headers-hsts to enable HSTS header on my spring boot application. Despite of making the required changes, Strict-Transport-Security
header is not appearing the response.

.maxAgeInSeconds(31536000);
}
}
List of headers:
cache-control →no-cache, no-store, max-age=0, must-revalidate
content-language →en-GB
content-type →text/html;charset=UTF-8
date →Thu, 24 May 2018 14:10:29 GMT
expires →0
pragma →no-cache
transfer-encoding →chunked
x-application-context →application:9000
x-content-type-options →nosniff
x-frame-options →SAMEORIGIN
x-xss-protection →1; mode=block
Am I missing anything?
In accordance with RFC6797, the HSTS header is only injected into HTTPS responses.
