Seguem as Classes:

Controlador

package vipList.config.controllers;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.stereotype.Service;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import vipList.model.entities.Convidado;
import vipList.model.repository.ConvidadoRepository;

@Controller
public class ConvidadosController {

    private static final String SLASH = "/";
    private static final String LISTA_CONVIDADOS = "listaConvidados";
    private static final String INDEX = "index";

    @Autowired
    private ConvidadoRepository aRepository;

    @RequestMapping(SLASH)
    public String getIndexPage() {
        return INDEX;
    }

    @RequestMapping(SLASH + LISTA_CONVIDADOS)
    public String getListaConvidados(Model pModel) {

        Iterable<Convidado> iterableConvidados = this.aRepository.findAll();
        pModel.addAttribute(iterableConvidados);

        return LISTA_CONVIDADOS;
    }

}

Segue a classe de Configuração:

package vipList.config;

import javax.sql.DataSource;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.jdbc.datasource.DriverManagerDataSource;

import vipList.model.repository.ConvidadoRepository;

@SpringBootApplication
public class Configuration {

    private static final String ROOT_PASSWORD = "RootPassword";
    private static final String ROOT_USER = "root";
    private static final String MY_VIP_LIST_DATABASE = "myviplist";
    private static final String JDBC_MYSQL_LOCALHOST_3306 = "jdbc:mysql://localhost:3306/";
    private static final String COM_MYSQL_JDBC_DRIVER = "com.mysql.jdbc.Driver";

    @Bean
    public DataSource getDataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(    COM_MYSQL_JDBC_DRIVER);
        dataSource.setUrl(                JDBC_MYSQL_LOCALHOST_3306    +    MY_VIP_LIST_DATABASE);
        dataSource.setUsername(            ROOT_USER);
        dataSource.setPassword(            ROOT_PASSWORD);

        return dataSource;
    }

    public static void main(String[] args) {
        SpringApplication.run(Configuration.class, args);
    }

}

Onde eu estou errando?
