💡 Hint

Common Mistakes

Using the full file name including extension instead of just the base name.

Trying to set the file path instead of the config name.

Setting spring.config.name to config tells Spring Boot to look for config.yml or config.properties instead of the default application.yml.

💡 Hint

Common Mistakes

Using classpath: when the file is outside the classpath.

Omitting the prefix and causing Spring Boot to not find the file.

Using spring.config.location with file:./config/ tells Spring Boot to load config files from the local config folder.

💡 Hint

Common Mistakes

Including the file extension in the config name.

Using the default name when trying to override.

The spring.config.name property expects the base name without extension. Using config is correct, not config.yml.

💡 Hint

Common Mistakes

Using classpath locations when files are outside the classpath.

Not separating locations with commas.

You can specify multiple config locations separated by commas. Here, file:./config/ and file:/etc/config/ are two local folders Spring Boot will check.

This command runs the app with a custom config file base name customconfig, loads config files from file:./custom/, and activates the dev profile.
