[SPRING] JPA Hibernate Persistence 예외 [PersistenceUnit : default] Hibernate SessionFactory를 빌드 할 수 없다.

JPA Hibernate Persistence 예외 [PersistenceUnit : default] Hibernate SessionFactory를 빌드 할 수 없다.

나는 JPA Hibernate와 mysql을 사용하여 내 DB와의 연결을 정리하려고 노력했지만, 어떤 이유로 든 Tomcat 서버를 시작할 때 동일한 예외가 발생한다.

 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

이것은 내 JPA 구성 클래스입니다.

@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;
}

}

이 시점에서 나는 시도 할 다른 것을 생각할 수 없다. 도움이 많이 필요하다.

편집 : 이것은 전체 스택 트레이스입니다.

해결법

1. ==============================

   1.문제는 당신이 MYSQL 데이터베이스에 연결할 수 없으므로 세션 팩토리를 만들 수 없다는 오류가 발생하고 있다는 것입니다.

   문제는 당신이 MYSQL 데이터베이스에 연결할 수 없으므로 세션 팩토리를 만들 수 없다는 오류가 발생하고 있다는 것입니다.

   아래 오류를 참조하십시오.

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

   이는 사용자 이름이 채워지지 않음을 나타냅니다.

   시스템 속성을 다시 확인하십시오.

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

   종속성 문제를 가리키는 일부 패키지가 누락 된 것 같습니다.

   package org.gjt.mm.mysql does not exist
   

   종속성을 확인하려면 mvn dependency : tree 명령을 실행하십시오.

2. ==============================

   2.MySQL에서 스키마를 작성하지 않았기 때문에 모든 관련 종속성이 존재하더라도이 오류가 발생했습니다.

   MySQL에서 스키마를 작성하지 않았기 때문에 모든 관련 종속성이 존재하더라도이 오류가 발생했습니다.

   자동으로 생성 될 것이라고 생각했지만 그렇지 않았습니다. 테이블 자체가 작성 되더라도 스키마를 작성해야합니다.

3. ==============================

   3.그 종류의 오류에 관한 몇 가지 문제점을 발견했습니다.

   그 종류의 오류에 관한 몇 가지 문제점을 발견했습니다.
