As shown in the following code, here we will be creating Spring MVC specific Java configurations (SpringMVCConfig.java):

@Configuration
@EnableWebMvc
@ComponentScan( basePackages = "com.packtpub")
public class SpringMVCConfig implements WebMvcConfigurer {
    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        registry.jsp().prefix("/WEB-INF/views/").suffix(".jsp");
    }
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/login");
    }
}

In this configuration, set the view's prefix and suffix. Make sure that your login view controller is added explicitly, as we don't have a route defined in our controller (we will see the controller later).
