Erro de criação do EntityManager quando uso a versão 1.4.1 do SpringBoot e seus respectivos Starters

Caramba, eu to usando a mesma versão e não estou tomando esse problema... bem estranho.. só por desencargo.. tira as tags <version>das dependências.. vc não precisa disso, pq já está definido no parent.

Eu tbm não consigo ver problema no seu código. Outra alteração que vi, mas acho que não pode ser o problema, é o scope na dependencia do MySQL

Removi os Versions dos demais pacotes, e funcionou. O engraçado é que fiz isso antes e não tinha funcionado.

Talvez algum pacote tenha baixado corrompido e o Maven depois conseguiu se resolver? Já tive problemas no passado por esse motivo, mas nesses casos precisei excluir manualmente o pacote.

Bom, o importante é que funcionou (pena não ter ficado muito claro o motivo do problema).

Obrigado pelo apoio e ajuda!

Estava com o mesmo problema, tive que trocar pra 1.4.0 pra poder funcionar

Oi Caio, tudo bem? Pode ser um possível bug sim, tentei encontrar alguma issue no github e não encontrei nada. O estranho é que estou fazendo este projeto atualmente e tive o mesmo problema.

Na versão 1.4.0 tudo funciona. Na versão 1.4.1 você terá esse erro esquisito ai, e na versão 1.4.2 tudo volta ao normal. Arrisco dizer que pode ser alguma dependencia do starter que teve algum problema talvez.

Pode usar a versão 1.4.2 que saiu recentemente que vai funcionar sem problemas. Pelo menos a questão das coisas que fiz até agora.

Bom, só pra te lembrar, marca a questão como resolvida tá bom? Um abraço!

Bom dia Caio.

Chegaste a criar o banco de dados? Caso não, experimente criar a base de dados e suas configurações (tabela e colunas).

Estou usando a versão 1.4.2 e com isso tudo funcionou corretamente.

Também adicionei as seguintes anotações na minha classe de configuração:

@ComponentScan(basePackages = { "br.com.listavip.configuration", "br.com.listavip.controller" })
@EntityScan(basePackages = { "br.com.listavip.model" })
@EnableJpaRepositories(basePackages = { "br.com.listavip.repository" })
@SpringBootApplication
public class Configuration {
...
}

Olá,

Estava usando o Spring Boot na versão 1.4.0, depois 1.4.1 e agora 1.4.2, sem problemas em nenhuma dessas versões.

    }

    @Bean

        props.setProperty("hibernate.show_sql", "true");
        props.setProperty("hibernate.hbm2ddl.auto", "update");
        return props;
    }

    @Bean

            DataSource dataSource, Properties additionalProperties) {
        LocalContainerEntityManagerFactoryBean factoryBean = 
                new LocalContainerEntityManagerFactoryBean();
        factoryBean.setPackagesToScan("br.com.alura.listavip");
        factoryBean.setDataSource(dataSource);

        JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        factoryBean.setJpaVendorAdapter(vendorAdapter);
        factoryBean.setJpaProperties(additionalProperties);

        return factoryBean;
    }

    @Bean
    public JpaTransactionManager transactionManager(EntityManagerFactory emf) {
        return new JpaTransactionManager(emf);
    }

}

Tive o mesmo problema, também resolvi voltando a versão para 1.4.0
