How do I troubleshoot my Spring Boot deployment issues?

I'm having trouble deploying my Spring Boot application. It keeps failing. What should I check first?

First, check the logs for any error messages. They can provide clues about what's going wrong.

I looked at the logs, and it says 'Port already in use'. What does that mean?

It means another application is using the same port your Spring Boot app is trying to use. You can either stop that application or change the port in your application properties.

How do I change the port in my application properties?

You can change the port by adding server.port=8081 (or any other port number) in your application.properties file.

Thanks! That helped. What if I encounter a database connection error next?

If you face a database connection error, check your database URL, username, and password in the configuration.
