When i run the demo application with this pom i am getting

io.awspring.cloud.paramstore.AwsParamStorePropertySources$AwsParameterPropertySourceNotFoundException: com.amazonaws.services.simplesystemsmanagement.mode

It is trying to access paramstore which is what i want but when I change the springboot version to 2.4.4 and spring-cloud.version to 2020.0.2 and I run the same application now It is not trying to connect to aws paramstore.

Can someone explain how i can access paramstore if I upgrade to springboot to 2.4.4

Answer 1

In spring-cloud 2020.0.0 (aka Ilford), the bootstrap phase is no longer enabled by default. In order enable it you need an additional dependency:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency> 

However, starting at spring-cloud-aws 2.3, allows import default aws parameterstore keys using spring.config.import=aws-parameterstore:

You can find this information at the end of the following section https://docs.awspring.io/spring-cloud-aws/docs/2.3.0/reference/html/index.html#integrating-your-spring-cloud-application-with-the-aws-parameter-store
