STS tries to warn you when editing application.properties, if any properties do not match your configuration classes.
Unfortunately it sometimes gets out of step and does not give correct warnings.
I had a few intermittent instances of this which were cleared by refreshing/rebuilding/reloading.
However one persistent one was that whilst Spring Boot was happy with the map[key] syntax for specifying a property for a map entry, the IDE continued to give a warning on this.
In the end I could not resolve this, but using the map.key syntax instead was fine and the IDE was happy with this and did not give warnings.
The only real need for the [] syntax would be to support keys with special characters in like “.”, but in my case this was not an issue and I would normally avoid this anyway if at all possible.
