Question

I’m used to Java EE but not Spring MVC. I’ve just created a new Spring MVC project and in the controller I have the following code generated.

@Controller
public class LoginController {

    private static final Logger logger = LoggerFactory.getLogger(LoginController.class);

    /**
     * Simply selects the home view to render by returning its name.
     */
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String login(Locale locale, Model model) {
        logger.info("Welcome home! the client locale is "+ locale.toString());


        return "home";
    }

}

Normally, I would expect one of the parameters to be request and the other response, how do I find these values with Spring MVC? For instance, I want to capture a username and password that will get sent here? Is there something similar to a doGet and doPost method in Spring MVC?

Answer 1

If you want to capture parameters called username and password, then just declare them as method parameters:

public String login(Locale locale, Model model, String username, String password) {

Spring will supply them, or throw an exception if they’re not present.

You could equally declare an HttpServletRequest parameter if you choose to:

public String login(Locale locale, Model model, HttpServletRequest request) {

But the first approach is cleaner.
