Credentials of cloudfoundry service cannot be resolved anymore

[rreitmann]

We have just upgraded from 2.2.4 to 2.2.5 and the following property of a user-provided service on cloudfoundry (PWS in our case) cannot be resolved anymore:
Could not resolve placeholder 'vcap.services.elastic.credentials.sslUri' in value "${vcap.services.elastic.credentials.sslUri}"

We use that property in our application-dev.yml.

Since this causes the application startup to fail, we currently cannot upgrade. Is there any workaround?

I have a similar issue after the same (2.2.4 -> 2.2.5) upgrade with a different provider (Swisscom).

@rreitmann & @tornaia I guess this is caused by 544dca7 respectively #18915 . I would try wrapping sslUri with []. E.g. ${vcap.services.elastic.credentials[sslUri]} - at least until the Spring Boot team has a better recommendation/fix.

[rreitmann]

@dreis2211 Your workaround works for me! Thanks a lot and I think that this really demonstrates the power 💪 of the spring boot community 😄

IMHO someone should adjust the documentation of CloudFoundryVcapEnvironmentPostProcessor in case this change has been intended...

[dreis2211]

@rreitmann Glad this works for you. In case this wasn't intended, I'm also happy to provide a fix for it and allowing uppercase keys again.

[tornaia]

Thank you @rreitmann and @dreis2211! The suggested workaround works very well! ❤️😄

Thanks @dreis2211 the suggested workaround also helps in case of underscores, even with the dot before the brackets!

My case:
@Value("${vcap.services.backend-authentication.credentials.[key_password]}")

As mentioned in #20364, @ConfigurationProperties also seem to be broken.
Wrapped properties are not automatically mapped to the fields inside the @ConfigurationProperties-annotated class:

vcap.services.asdcs-document-db.credentials.[ca_cert] = https://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem
vcap.services.asdcs-document-db.credentials.[instance_identifier] = d1234567890-12345671-12351
vcap.services.asdcs-document-db.credentials.[reader-endpoint] =  docdb-with-identifier-reader.eu-west-1.docdb.amazonaws.com

results in:

@Configuration
@ConfigurationProperties("vcap.services.asdcs-document-db.credentials")
public class CloudFoundryAwsDocumentDbCredentials {

  String caCert; // is null
  String instanceIdentifier; //is null
  ...
  String readerEndpoint; //is null
  ...
}
