JPA-Hibernate-Persistenzausnahme [PersistenceUnit: default] Hibernate SessionFactory kann nicht erstellt werden

Ich habe versucht, eine Verbindung zu meiner Datenbank mit JPA Hibernate und Mysql herzustellen, aber aus irgendeinem Grund, egal was ich versuche, bekomme ich beim Starten des Tomcat-Servers die gleiche Ausnahme:

 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

Dies ist meine JPA-Konfigurationsklasse:

@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;
}

}

An diesem Punkt fällt mir nichts anderes ein, um es zu versuchen. Jede Hilfe ist sehr verpflichtet

Edit: Dies ist der gesamte Stacktrace

Das Problem ist, dass Sie keine Verbindung zur MySQL-Datenbank herstellen können. Daher wird eine Fehlermeldung ausgegeben, die keine Sitzungsfabrik erstellen kann.

Bitte sehen Sie den Fehler unten:

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

was darauf hindeutet, dass username keine populated erhält.

Bitte überprüfen Sie die Systemeigenschaften  

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

einige Pakete scheinen ebenfalls zu fehlen und weisen auf ein Abhängigkeitsproblem hin:

package org.gjt.mm.mysql does not exist

Führen Sie einen mvn dependency:tree-Befehl aus, um nach Abhängigkeiten zu suchen

Ich habe diese Fehlermeldung erhalten, obwohl alle relevanten Abhängigkeiten vorhanden waren, da ich das Schema in MySQL nicht erstellt hatte. 

Ich dachte, es würde automatisch erstellt werden, war es aber nicht. Obwohl die Tabelle selbst erstellt wird, müssen Sie das Schema erstellen.

Ich habe ein Problem mit dieser Art von Fehler gefunden 

  1. Datenbankbenutzername oder -kennwort stimmen nicht mit der MySQL-Datenbank oder einer anderen Datenbank überein. Stellen Sie application.properties bitte so ein



# ===============================
# = 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

Ausgabe Nr. 2.

Ihr lokaler Server weist zwei Datenbankserver und diesen Datenbankserver-Konflikt auf. dieser Konflikt wie dieser mysql server & xampp oder lampp oder wamp server. Bitte eine der Datenbanken wie mysql server , weil xampp oder lampp server automatisch mysql server auf diesem Rechner installiert wird
