Secrets Manager integration with @ConfigurationProperties is unclear

[ofir-popowski]

The documentation states:

Fetched secrets can be referenced with @Value, bound to @ConfigurationProperties classes, or referenced in application.properties file.

but there's no example or explanation how this works. Say I have the following

@ConfigurationProperties("custom")
data class CustomProperties(
  val name: String,
  val key: String
)

my application.properties looked like this

custom.name=name
custom.key=key

Now I'm working on migrating those to secrets manager, and I have created a JSON secret under test/custom, and removed the previous properties and replaced them with spring.config.import=aws-secretsmanager:test/custom.

What else to I need to do to ensure that my configuration properties can be properly populated from this secret?

How does your JSON secret look like? There's nothing more you should do, this should work.

My JSON was:

{
  "name": "name",
  "key": "key"
}

I forgot to update that after a couple of days I figured out that the prefix is mandatory, so spring.config.import=aws-secretsmanager:test/custom?prefix=custom worked
