Exception de persistance JPA Hibernate [PersistenceUnit: défaut] Impossible de créer Hibernate SessionFactory

J'ai essayé de régler une connexion à ma base de données avec JPA Hibernate et mysql, mais pour une raison quelconque, peu importe ce que j'essaie, lors du lancement du serveur Tomcat, la même exception se produit:

 org.springframework.beans.factory.BeanCreationException: Error creating     bean with name 'localContainerEntityManagerFactoryBean' defined in class path resource [core/JPAConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Factory method 'localContainerEntityManagerFactoryBean' threw exception; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

Ceci est ma classe de configuration JPA:

@Configuration
@EnableJpaRepositories("core.repository")
@EnableTransactionManagement
@EnableCaching
public class JPAConfig {

@Value("${db.jdbcURL}")
private String jdbcURL;

@Value("${db.user}")
private String user;

@Value("${db.password}")
private String password;

@Value("${db.generateDDL}")
private Boolean generateDDL;

@SuppressWarnings("Duplicates")
@Bean
public DataSource dataSource() {
    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setDriverClassName(Driver.class.getName());
    dataSource.setUrl("jdbc:mysql://localhost:3306/movierentaldb");
    dataSource.setUsername(System.getProperty("root"));
    dataSource.setPassword(System.getProperty("mdie1767"));
    dataSource.setInitialSize(2);
    dataSource.setMaxActive(5);
    return dataSource;
}

@Bean
public LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean(){
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    vendorAdapter.setDatabase(Database.MYSQL);
    vendorAdapter.setGenerateDdl(generateDDL);
    vendorAdapter.setShowSql(true);

    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();

    factory.setJpaVendorAdapter(vendorAdapter);

    factory.setPackagesToScan("core.model");

    factory.setDataSource(dataSource());

    factory.afterPropertiesSet();
    return factory;
}

@Bean
public EntityManagerFactory entityManagerFactory(){
    return localContainerEntityManagerFactoryBean().getObject();
}



@Bean
public EntityManager entityManager(){
    return entityManagerFactory().createEntityManager();
}

@Bean
PlatformTransactionManager transactionManager(){
    JpaTransactionManager manager = new JpaTransactionManager();
    manager.setEntityManagerFactory(entityManagerFactory());
    return manager;
}

@Bean
public HibernateExceptionTranslator hibernateExceptionTranslator(){
    return  new HibernateExceptionTranslator();
}

@Bean
public CacheManager cacheManager(){
    GuavaCacheManager guavaCacheManager = new GuavaCacheManager();
    guavaCacheManager.setCacheBuilder(CacheBuilder.newBuilder().expireAfterAccess(2, TimeUnit.HOURS));
    return guavaCacheManager;
}

}

À ce stade, je ne peux penser à rien d’autre à essayer. Toute aide est de la plus haute importance.

Edit: Ceci est le stacktrace entier

Le problème est que vous ne parvenez pas à vous connecter à la base de données MYSQL et qu’il génère donc une erreur indiquant qu’il ne peut pas créer de fabrique de sessions.

S'il vous plaît voir l'erreur ci-dessous:

 Caused by: Java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO)

ce qui indique que username n'obtient pas populated.

Veuillez revérifier les propriétés du système  

dataSource.setUsername(System.getProperty("root"));

certains paquets semblent également manquer, ce qui indique un problème de dépendance:

package org.gjt.mm.mysql does not exist

Veuillez exécuter une commande mvn dependency:tree pour vérifier les dépendances.

Je recevais cette erreur même lorsque toutes les dépendances pertinentes étaient en place car je n'avais pas créé le schéma dans MySQL. 

Je pensais que ce serait créé automatiquement mais ce ne l'était pas. Bien que la table elle-même soit créée, vous devez créer le schéma.

J'ai trouvé un problème avec ce genre d'erreur 

  1. Le nom d'utilisateur ou le mot de passe de la base de données ne correspond pas dans mysql ou une autre base de données. Veuillez définir application.properties comme ceci



# ===============================
# = DATA SOURCE
# ===============================

# Set here configurations for the database connection

# Connection url for the database please let me know "[email protected]"
spring.datasource.url = jdbc:mysql://localhost:3306/bookstoreapiabc

# Username and secret
spring.datasource.username = root
spring.datasource.password =

# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

# ===============================
# = JPA / HIBERNATE
# ===============================

# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager).

# Show or not log for each sql query
spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update): with "update" the database
# schema will be automatically updated accordingly to Java entities found in
# the project
spring.jpa.hibernate.ddl-auto = update

# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

Numéro 2.

Votre serveur local a deux serveurs de base de données et ceux-ci sont en conflit. Ce conflit ressemble à ceci serveur mysql & xampp ou lampp ou wamp serveur. S'il vous plaît une des bases de données comme serveur mysql car serveur xampp ou lampp installer automatiquement serveur mysql sur cette machine
