How do I use environment variables in Spring Boot?

How do I use environment variables in Spring Boot?

You can use environment variables in Spring Boot by accessing them through the @Value annotation or using the Environment object.

Can you give me an example of how to set an environment variable?

Sure! You can set an environment variable in your terminal like this: export MY_VARIABLE=value. Then, access it in Spring Boot with @Value("${MY_VARIABLE}") String myVariable;.

What if I want to use a properties file instead?

You can create an application.properties or application.yml file and define your variables there. Spring Boot will automatically load them.

Are there any best practices for managing environment variables?

Yes, it's best to keep sensitive information out of your codebase, use a .env file for local development, and consider using a secrets management tool for production.
