Answer 1

Community Edition of IntelliJ IDEA doesn't support autocompletion for application.properties. It is an Ultimate edition feature.

From this support thread:

Spring Boot framework is available in the Ultimate edition of IntelliJ IDEA only. It comes as a bundled plugin and is enabled by default.
