JPA Hibernate pour la Persistance exception [PersistenceUnit: par défaut] Impossible de construire 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 j'obtiens la même exception:

 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 pas penser à autre chose à essayer..toute aide est bien obligé

Edit: C'est l'ensemble de la stacktrace

le problème est que vous n'êtes pas en mesure d'obtenir une connexion à la base de données MYSQL et donc il lance une erreur disant que vous ne pouvez pas construire une usine de session.

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 username obtenir populated.

please reveck system properties

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

certains paquets semblent manquer aussi bien pointant vers un problème de dépendance:

package org.gjt.mm.mysql does not exist

s'il vous Plaît exécuter un mvn dependency:tree commande pour vérifier les dépendances

répondu shankarsh15 2018-02-08 10:35:42

j'ai eu cette erreur même lorsque toutes les dépendances pertinentes étaient en place parce que je n'avais pas créé le schéma dans MySQL.

je pensais qu'il serait créé automatiquement mais il ne l'était pas. Bien que la table elle-même sera créée, vous devez créer le schéma.

j'ai trouvé quelques question au sujet de ce genre d'erreur

  1. nom d'utilisateur ou mot de passe de la base de données ne correspondent pas dans le mysql ou autre base de données. Veuillez installer l'application.propriétés comme ceci

  

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

# Set here configurations for the database connection

# Connection url for the database please let me know "mondolmislam@gmail.com"
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

Problème n ° 2.

votre serveur local a deux serveurs de base de données et ces conflits de serveur de base de données. ce conflit comme ceci serveur mysql & xampp ou lampp ou wamp le serveur. Veuillez l'un de la base de données mysql le serveur parce que xampp ou lampp serveur install automatically serveur mysql sur cette machine
