Importei o projeto Maven...

Criei um módulo "quickstart" e um "webapp" nesse projeto...

Configurei as dependências do "Javax", do "Spring", os plugins do "Maven" e os dois módulos no pom.xml do projeto Maven...

Onde eu devo criar o .jsp que irá receber os dados?

Segue abaixo pom.xml:

Obrigado pela ajuda!!

Criei dentro do módulo webapp, na pasta:

src/main/webapp/WEB-INF/jsp

O formulario.jsp

Está correto ?

Eu importei o projeto, criei os módulos (um quickstart e outro webapp), configurei o Maven pra usar o Spring, e adicionei as dependências do Spring e do Hibernate no pom.xml do “Projeto Maven”...

Criei um formulario.jsp no módulo webapp, na pasta src/main/webapp/WEB-INF/views (que é o padrão dos .jsp no Spring)

Criei a classe modelo “Produto”, criei o ProdutoController e fiz o mapeamento com o @RequestMapping.

Quando eu clico com o direito no projeto e estolho Run on Server, carrega normalmente a tela do index.jsp (Hello World!)

Mas quando eu digito /nomeQueEstaNoRequestMapping, gera erro 404, e a msg no console:

mar 13, 2016 11:45:37 PM org.springframework.web.servlet.PageNotFound noHandlerFound
ADVERTÊNCIA: No mapping found for HTTP request with URI [/fiveware-test-web/form] in DispatcherServlet with name 'spring mvc'

Está faltando algum mapeamento, ele está errado... Ou está faltando alguma dependencia no pom.xml ??

Obrigado pela atenção!!

Oi Ewerton,

Você colocou @Controller em cima da classe ProdutoController?

Além do @RequestMapping (que vai no método), precisa usar a @Controller (que vai na classe).

Abraço

Sim coloquei...

package org.fiveware.controller;

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

@Controller
public class ProdutoController {

    @RequestMapping("/form")
    public String formulario() {
        return "formulario";
    }
}

Deixa eu ver sua configuração XML e também coloca aqui a StackTrace completa para ver o erro todo.

Abraço

Obrigado pela tentativa de me ajudar Paulo Alves Jr !!

Mas meu tempo para fazer a prova acabou...

Abraço

Ewerton, vamos tentar matar esse exercicio, como pratica mesmo, que acha? E mandar mesmo assim la pra empresa. Essa perseveranca sempre da uma impressionada.
