Quais são os arquivo de configuração necessários para o starter JPA

Todas as dependências declaradas no arquivo pom.xml do meu projeto são compatíveis com as versões utilizadas no curso, porém quando executo o server recebo o erro abaixo. Tem algum arquivo de configuração que é necessário incluir na pasta resources ou META-INF?

Olá Audrin,

Tenho algumas sugestões, talvez uma delas resolva seu problema.

Veja se você possui o driver do mysql no seu pom, conforme abaixo:

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.6</version>
        </dependency>

Se você configurou o banco via application.properties, veja se ele possui todas as configurações abaixo:


server.port=9000

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/nome_do_seu_banco
spring.datasource.username=usuario_do_seu_banco
spring.datasource.password=senha_do_seu_banco

Se você está configurando o banco diretamente no código, veja se ele está parecido com o código abaixo:

    @Bean
    public DataSource buildDataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();                
        dataSource.setUrl("jdbc:mysql://localhost:3306/nome_do_seu_banco");
        dataSource.setUsername("usuario_do_seu_banco");
        dataSource.setPassword("senha_do_seu_banco");                
        return dataSource;
    }

Se nada disso funcionar, eu pediria para você postar o seu application.properties e a classe que starta o spring.

Se você preferir, você pode verificar o código do projeto no meu github da época que fiz o curso, ele está funcionando normalmente:

Olá, Denis muito obrigada :)
