Olá Daniel, blz? Posta ai pra gente sua classe HomeController e a outra classe que extends AbstractAnnotationConfigDispatcherServletInitializer.

package toko.da.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("/home")
    public String home(){
        System.out.println("Home controller home");
        return "home";
    }
}

package toko.da;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class ServeletSpring extends AbstractAnnotationConfigDispatcherServletInitializer{

    @Override
    protected Class<?>[] getRootConfigClasses() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        // TODO Auto-generated method stub
        return new Class[]{AppWebConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        // TODO Auto-generated method stub
        return new String[] {"/"};
    }

}

Eu acho que estou fazendo algo errado na hora de criar um projeto, estou usando o JBoss developer file->new Maven project -> nesse momento pede para selecionar o archetype e eu estou ussando o spring-boot-black-archetype

com o código acima aconteceu esse erro "Circular view path [home]: would dispatch back to the current handler URL [/home] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)"

Daniel, qual a URL você está acessando?

Disponibiliza seu projeto lá no GitHub pra eu fazer um teste aqui no meu pc.

Daniel Massanori, no

resolver.setPrefix("WEB-INF/views/");

da sua classe AppWebConfig está faltando um / antes de WEB-INF.

Olá Boa Noite, Estou com o mesmo problema:

@Controller
public class HomeController {
    @RequestMapping("/home")
    public String index(){
        System.out.println("Exibindo a home da CDC");
        return "teste";

    }
}

public class ServletSpringMVC extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return null;
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] {AppWebConfiguration.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }

}

@EnableWebMvc
@ComponentScan(basePackageClasses = { HomeController.class })
public class AppWebConfiguration {
    @Bean
    public InternalResourceViewResolver internalResourceViewResolve() {
        InternalResourceViewResolver resolve = new InternalResourceViewResolver();
        resolve.setPrefix("/WEB-INF/views/");
        resolve.setSuffix(".jsp");
        return resolve;
    }
}

Obs: se eu alterar as paginas para .xhtml vai funcionar também??

Cleiton, aparentemente tá tudo correto com as suas configurações.

Você não tá errando a url para acessar sua rota no browser?

Lembre-se, uma rota é acessada assim:

http://localhost:8080/(nome da sua aplicação)/(rota do seu controller)

ou seja, se o nome da aplicação (contexto) for "loja" e você tem uma rota chamada "/home", então sua url ficará assim:

http://localhost:8080/loja/home

Outro erro que pode ser é, vc tem uma pagina chamada teste.jsp em /WEB-INF/views/?

Olá João Blza, seguinte, estou usando assim:

http://localhost:8080/springalura/home

e eu tenho uma página teste.jsp. Já tentei usar teste.xhtml e alterar o resolve.setSuffix para ".xhtml ", mas também não funcionou. Estou usando o tomcat 9. Também tentei rodar com o wildfly 10 mas deu o mesmo erro....

Hum, vc pode postar o log que aparece no seu console?

Pessoal, eu também estava com o mesmo problema, vou citar abaixo os trechos onde devem tomar atenção, pois foi onde errei:

@Bean
    public InternalResourceViewResolver internalResourceViewResolver(){
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");

        return resolver;
    }

• Não esqueçam do @Bean, se estiver retornando o erro: "Could not resolve view with name 'htmlviews/index.html' in servlet with name 'dispatcher' .." o problema provavelmente é esse.
• Atentem ao minuto 7:34 de vídeo, tentem fazer exatamente igual o instrutor, aqui visualmente estava igual mas não estava pegando o setPrefix e o setSuffix corretos, utilizem o ctrl+space.
• Outro ponto no mesmo minuto, é quando ele dá CTRL+1, eu substitui pra resolver na mão, por isso não pegava a classe correta, aparentemente estava igual, só que não funcionava (inclusive um amigo acima escreveu "resolve", o problema dele é exatamente o que tive). Espero ter ajudado.

Estou com o mesmo problema, esta tudo correto e não funciona, algum professor pode nos ajudar aqui por favor!
