This guide walks you through the process of creating a Spring application.
What you’ll build
You’ll build a Spring application.
What you’ll need
Create a resource controller
Create a new controller for your Spring application:
The above example does not specify
Make the application executable
Although it is possible to package this service as a traditional WAR file for deployment to an external application server, the simpler approach demonstrated below creates a standalone application. You package everything in a single, executable JAR file, driven by a good old Java
main() method. Along the way, you use Spring’s support for embedding the Tomcat servlet container as the HTTP runtime, instead of deploying to an external instance.
Logging output is displayed. The service should be up and running within a few seconds.
Test the application
Now that the application is running, you can test it.
Congratulations! You’ve just developed a Spring application!
