How to integrate AWS Secret Manager with Spring Boot Application

I have a requirement to retrieve credentials from AWS Secret Manager, and I found that I need to add the gradle dependency for the following starter

spring-cloud-starter-aws-secrets-manager-config

Also, i found that I need to add the following settings in Bootstrap.yml

Property Configurations

I'm unclear how secret key could be accessed in my Spring Boot Application if someone could chime in much appreciated.

I would like to share my findings on SecretManager integration with Spring Boot application.

Step 1. Add spring-cloud-starter-aws-secrets-manager-config dependency in Spring Boot Application ( Gradle and Maven ways of adding dependency is different).

Step 2. Add the following configuration in bootstrap.yml file.

aws:
  secretsmanager:
    prefix: /secret
    defaultContext: application
    profileSeparator: _
    failFast: true
    name: <service_name>
    enabled: true

Step 3. create secrets in AWS Management console for the region required.

There are two secrets contexts

1. Application context - Shared secrets across all services.
2. Service context - secrets specific to service.

Final note on creating secrets,Secrets could be created for each environments.

For example,

/secret/service_name_dev/username

/secret/service_name_prod/username

Application context secrets could be created according to following format.

/secret/application/username

Once Spring Boot application started with above settings, Application will load secrets from AWS Secret Manager based on active profile.

For example, for a dev profile, it will load the secret /secret/service_name_dev/username, and the value could be accessed in configuration as well as in classes using ${username} mapping.
