Troubleshooting application.yml Not Loading in Spring Boot 2 with Apache CXF

If you are developing a Spring Boot 2 application with Apache CXF, you might encounter an issue where your application.yml file is not loading correctly, resulting in an empty configuration object. This can be a frustrating problem for new developers. Don't worry; you are not alone in this! In this guide, we will explore the root of the problem and the straightforward solution for ensuring your properties load as expected.

Understanding the Issue

When working with Spring Boot, its primary goal is to streamline the setup process for your applications. However, if the application is unable to locate and load your application.yml file, it can lead to unexpected behavior or missing configurations.

Common Symptoms

The application starts but retrieves empty configuration values.

Manually forcing the location with spring.config.location=classpath:application.yml solves the problem temporarily.

Configuration is located in src/main/resources, but is still not recognized without proper context.

Solution Breakdown

The good news is that fixing this issue often involves a simple configuration update. Below, we’ll go through the solution step-by-step:

1. Check Your Current Configuration

You might be using the property -Dspring.config.location in your Tomcat setenv.bat file to define where Spring Boot should look for configuration files. While this approach can work, it can also cause limitations, preventing the application from accessing other configuration files.

2. Shift to Additional Location Property

Instead of setting -Dspring.config.location, you can switch to using -Dspring.config.additional-location. This property allows you to specify additional configuration files without overriding the default ones.

Steps:

Locate your setenv.bat file, which is typically used to set environment variables for Tomcat.

Change the configuration from:

to:

Restart your application server to apply the changes.

3. Verify Your Setup

After making the changes, verify that:

The application.yml is still present in the src/main/resources directory.

Your application starts without any issues and that the configuration values are now being recognized.

Example Code for Clarity

Here’s an outline of what your Spring Boot application main class might look like for reference:

Benefits of this Approach

Flexible File Loading: It enables Spring Boot to locate additional config files without losing the benefits of the built-in configuration structure.

Minimized Issues: This adjustment helps clear up common issues seen in deployments using Tomcat and improves application configuration management.

Conclusion

In summary, if you find that your application.yml is not being loaded correctly in your Spring Boot 2 application with Apache CXF, remember to check how you specify the configuration file locations. By using -Dspring.config.additional-location instead of -Dspring.config.location, you can ensure that your YAML properties are loaded as intended.

With this quick fix, you should be able to smoothly run your application with all configurations in place!
