Values not populated from application.properties files

[falk-stefan]

Note that all other settings are working just fine.

I only recently adderd Spring Cloud GCP - it's the only piece that does not work as expected currently.

I am running a particular profile which points locally to a credentials file as follows:

spring.cloud.gcp.project-id=<project-id>
spring.cloud.gcp.credentials.location=file:/path/to/file/credentials.json

If I run the same thing with GOOGLE_APPLICATION_CREDENTIALS=/path/to/file/credentials.json it's working.

What am I missing?

Caused by: java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.

I am using spring-cloud-gcp-starter (gradle):

// Spring Cloud Google Secret Manager
implementation 'org.springframework.cloud:spring-cloud-gcp-starter:1.2.6.RELEASE'
implementation 'org.springframework.cloud:spring-cloud-gcp-starter-secretmanager:1.2.6.RELEASE'

Update

It appears to be the same for other properties e.g. database name:

spring.cloud.gcp.sql.database-name=<db-name>

Debugging the code confirms that the properties are not getting set:

It looks like you're using the secretmanager module -- those settings have to be put in a bootstrap.properties instead of application.properties.

This is because the secrets are loaded by the "bootstrap phase" of Spring. The bootstrap.properties file is placed in the resources/ directory same as the application.properties file.

Let me know if this fixes the problem for you. I will also look into ways of documenting this better -- were you looking at sample apps or docs, etc.?

EDIT: Not sure why the database name is not being picked up though. Those settings should be correctly read by application.properties. We would probably need to see more dependencies being used in the project to understand.

Hi @falk-stefan perhaps you can share the full credentials file and maybe the bootstrap file (if there), so we can get a full picture.

Please do not share the full credentials file. That's supposed to stay a secret ;-)

[kioie]

Oh..my bad!...I should have said, the applications.properties file and the bootstrap file ;-)

Sorry for the late response. I was somehow able to make this work but I cannot tell what the problem really was. But it was definitely something on my side so I guess we can close this issue. Thank you!
