Estou tendo o seguinte erro ao subir a aplicação(OBS: Não criei a tabela no MySql).

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

Você está usando o MySQL 5, correto? Tenta atualizar a versão do mysql connector do projeto:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.48</version>
</dependency>

Se for o MySQL 8:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.18</version>
</dependency>

Copiei o projeto da aula 02, mas agora estou com o seguinte erro:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set

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;

@SpringBootApplication
public class Configuracao {

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

    @Bean
    public DataSource dataSource(){
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/listavip");
        dataSource.setUsername("root");
        dataSource.setPassword("root");
        return dataSource;
    }

Oi Fernando,

Você está utilizando o MySQL 5? Pelo erro parece que esse driver não consegue se conectar ao seu banco de dados.

Trocando para o MySQL 5, tente fazer outro teste também, atualize no seu pom.xml a versão do mysql driver:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.47</version>
</dependency>
