SpringBoot : No matching bean found exception

Arun :

My login page in my first SpringBoot Application:

Main Class

@SpringBootApplication

public class MainGate extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(MainGate.class);
    }

    public static void main(String... args) {
        System.out.println("Booting .. ");
        SpringApplication.run(MainGate.class, args) ;
    }

}

Solution mentioned in How to configure spring boot mvc app for JSP? is not working.

user7294900 :

You found the right question but it doesn't seems you added the solution in the answer, you need to Add an InternalResourceViewResolver

This ViewResolver allows us to set properties such as prefix or suffix to the view name to generate the final view page URL:

@Bean
public ViewResolver getViewResolver(){
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    resolver.setViewClass(JstlView.class);
    return resolver;
}

and make sure you have in dependencies:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
