What does the ViewResolver class?

Ref:- http://howtodoinjava.com/2015/03/02/spring-mvc-interview-questions-with-answers/

ViewResolver is an interface to be implemented by objects that can resolve views by name. There are plenty of ways using which you can resolve view names. These ways are supported by various in-built implementations of this interface. Most commonly used implementation is InternalResourceViewResolver class. It defines prefix and suffix properties to resolve the view component.

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">     <property name="prefix" value="/WEB-INF/views/" />     <property name="suffix" value=".jsp" /> </bean>

So with above view resolver configuration, if controller method return “login” string, then the “/WEB-INF/views/login.jsp” file will be searched and rendered.
