In this tutorial we are covering full of spring security login example but with no database connection. With following tutorials I am thinking to add one with database. To understand basic spring security you may study this example. In this tutorial I used maven and you will find the pom.xml file as well and my favorite IDE IntelliJ. Let us get started with the project

import org.springframework.web.servlet.ModelAndView;

public class WelcomeController {

return modelAndView;
}
}
You may now deploy the application to the server and test it
