Troubleshooting Spring Cloud Config Client Configuration Issues After Upgrade to 2.4.0

Upgrading software can often lead to unexpected challenges, especially when working with complex frameworks like Spring. If you're facing issues with your Spring Cloud Config Client being unable to load configuration files from the Spring Cloud Config Server after upgrading to 2.4.0, you're not alone. This guide will walk you through the problem, the changes in the framework, and provide a clear solution to get your configuration files loading again.

The Problem

After upgrading to Spring Boot 2.4.0, some users have reported that their Spring Cloud Config Client is no longer able to read configuration files from the Spring Cloud Config Server. This problem can halt development processes and cause significant frustration. The reason for this behavior lies in a change in the defaults for bootstrapping in Spring Boot.

What Changed?

Starting with Spring Boot 2.4.0, bootstrapping is not enabled by default. This means that if you were relying on automatic configuration loading through the bootstrap process, you may need to take additional steps to restore this functionality.

The Solution

To resolve the issue, you will need to manually enable bootstrapping by adding a specific dependency to your project. Below are the steps to add the required dependency whether you are using Gradle or Maven as your build tool.

For Gradle Users

If you are using Gradle for your project, open your build.gradle file and add the following line to your dependencies:

This dependency allows your application to properly bootstrap and thus allows it to load the necessary configuration files from the config server.

For Maven Users

For those using Maven, you will need to include the same dependency in your pom.xml file as follows:

Summary of Changes Required

Add Dependency: Include spring-cloud-starter-bootstrap in your project.

Check Configurations: Ensure all configurations in the application are aligned with the Spring Cloud standards moving forward.

Final Thoughts

By following the steps outlined above, your Spring Cloud Config Client should now be able to read from the Spring Cloud Config Server once again. Keeping your dependencies up-to-date and paying attention to changes in framework initialization is crucial when upgrading.

If issues persist after following these instructions, consider checking your Spring Cloud and Spring Boot versions compatibility, as well as reviewing any existing configuration files for anomalies.



By understanding these changes and adjusting your dependencies, you can eliminate downtime and maintain a smooth development workflow. Happy coding!
