Inconsistent Behavior of Spring Boot Profiles with YAML Configuration in Java 17
I'm trying to implement I'm relatively new to this, so bear with me. I'm stuck on something that should probably be simple... I'm working with an scenario with managing different environments using Spring Boot profiles defined in a YAML configuration file. I have a `application.yml` that looks like this: ```yaml spring: profiles: active: dev --- spring: profiles: dev datasource: url: jdbc:mysql://localhost:3306/dev_db username: dev_user password: dev_pass --- spring: profiles: prod datasource: url: jdbc:mysql://localhost:3306/prod_db username: prod_user password: prod_pass ``` When I run my application with the command `mvn spring-boot:run -Dspring-boot.run.profiles=prod`, I expect it to pick up the `prod` configuration. However, I'm noticing that it still applies the `dev` settings intermittently, and I see logs that indicate it’s connecting to the `dev_db` instead of `prod_db`. I've verified that no other configurations (like `application-dev.yml` or `application-prod.yml`) exist that could override these settings. Also, I have cleared the cache and built the project afresh to avoid any lingering issues. I've tried using environment variables to set the active profile as well, but the behavior remains the same. What could be causing this inconsistent profile behavior? Any insight on how to ensure that the Spring Boot application reliably uses the correct profile configuration would be greatly appreciated. What's the best practice here? Any ideas how to fix this? I'm on Ubuntu 22.04 using the latest version of Java. What are your experiences with this?
