JPA Hibernate Persistence例外[PersistenceUnit：default] Hibernate SessionFactoryを構築できません

私はJPA Hibernateとmysqlを使用してDBへの接続を整理しようとしましたが、何らかの理由で、Tomcatサーバーを起動すると、同じ例外が発生します：

 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

これは私のJPA構成クラスです。

@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;
}

}

この時点で、他に試すことは考えられません。

問題は、MYSQLデータベースへの接続を取得できないため、セッションファクトリを構築できないというエラーがスローされることです。

以下のエラーをご覧ください：

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

usernameがpopulatedを取得していないことを指します。

システムのプロパティを再確認してください

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

いくつかのパッケージは依存関係の問題を指しているだけでなく、欠落しているようです：

package org.gjt.mm.mysql does not exist

mvn dependency:treeコマンドを実行して依存関係を確認してください

MySQLでスキーマを作成していないため、関連するすべての依存関係が設定されていても、このエラーが発生していました。

自動的に作成されると思いましたが、そうではありませんでした。テーブル自体は作成されますが、スキーマを作成する必要があります。

その種のエラーに関する問題を見つけました

  1. データベースのユーザー名またはパスワードがmysqlまたは他のデータベースと一致しません。 application.propertiesをこのように設定してください

ローカルサーバーには2つのデータベースサーバーがあり、それらのデータベースサーバーは競合しています。このような競合はmysql server＆xamppまたはlamppまたはwamp serverです。 mysql serverなどのデータベースのいずれかを選択してくださいxamppまたはlampp serverこのマシンにmysql serverを自動的にインストールするため
