@Value annotation not working with springboot 2.3.1
I have this test class with some test cases
class TestClass(@Value("\${s3.published.bucket}") private val publishedBucketName: String) { }
I have 2.1.8.Release currently for springBoot version and everything works fine, all tests are passing now i need to migrate to springboot 2.3.1.Release But it seems that @Value annotation is not able to pick value s3.published.bucket from my application.yml in src/main.
Application.yml
s3:
region: ${s3_region:eu-central-1}
published:
bucket:...
