Introduction

If you're developing a web application with Spring Boot and you're using Spring Cloud Config for external configurations, you might have encountered an issue where Google Secret Manager tokens are not being recognized. This problem can be frustrating, especially when your application requires secure credentials stored in Google Cloud Secret Manager.

In this guide, we'll delve into the specifics of this problem and provide a step-by-step solution to ensure your Spring Boot application can effectively utilize these tokens.

The Problem

When configuring your Spring Boot application, particularly when utilizing a configuration server, secure credentials stored in Google Cloud Secret Manager are often necessary. The configuration typically involves tokens formatted with the notation sm://. However, in some cases, the Spring Cloud Config section of your application.yml does not process these tokens correctly.

For example, the issue arises when the properties in the Spring Cloud Config section—like username and password—attempt to reference the Google Secret Manager tokens, but they don't resolve properly. On the other hand, properties outside this section can fetch the tokens without any problems.

Symptoms:

Tokens in the Spring Cloud Config section do not resolve to their respective secrets.

Plain text credentials work without issue in the application.yml.

Potential dependency issues or version mismatches.

The Solution

The good news is that this problem can be resolved by updating to more recent versions of Spring Boot and Spring Cloud dependencies. Here’s a detailed guide on how to implement this solution.

Step 1: Update the Spring Boot Version

The first step is to update the version of Spring Boot in your pom.xml. Switch to version 2.7.10:

Important Notes:

Ensure you have the necessary permissions set in Google Cloud for access to the secrets.

Restart your application after making these changes for them to take effect.

Conclusion

By following this guide, you should be able to resolve the issue of Google Secret Manager tokens not being processed correctly in your Spring Boot Cloud Config. Updating your Spring Boot and Spring Cloud dependencies is crucial to ensure your application can securely retrieve credentials stored in Google Cloud.

If you encounter further issues, consider checking the dependency compatibility or reaching out to community forums for more tailored assistance. Happy coding!
