How to start up spring-boot application via command line?

I presume you are trying to compile the application and run it without using an IDE. I also presume you have maven installed and correctly added maven to your environment variable.

To install and add maven to environment variable visit Install maven if you are under a proxy check out add proxy to maven

Navigate to the root of the project via command line and execute the command

mvn spring-boot:run

The CLI will run your application on the configured port and you can access it just like you would if you start the app in an IDE.

Note: This will work only if you have maven added to your pom.xml

You will need to build the jar file first. Here is the syntax to run the main class from a jar file.

java -jar path/to/your/jarfile.jar fully.qualified.package.Application
