Spring MVC 3.0 with STS Tutorial – Part I | duckranger.com: "Generally, a controller method should not return just a String. It should actually return a ModelAndView object, which contains both the model we discussed earlier, and the view to resolve (or rather – a way to find the view).
However, as you can see, in our generated Spring-MVC project, the controller method returns only a String, which contains the view name. This is alright, as long as we tell the container how it should resolve the view and serve the correct page to the client.

The InternalResourceViewResolver does exactly that. It is configured as a bean, and since it is the only view resolver configured, the Spring container knows that this is the one it should use. In essence, the InternalResourceViewResolver receives the result of the controller method (the String returned) – and is then in charge of mapping this result to an actual view."
