我一直在尝试用JPA Hibernate和mysql整理到我的数据库的连接，但由于某种原因，无论我怎么尝试，当启动tomcat服务器时，我得到了相同的异常：

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

字符串
这是我的JPA config class：

@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;
}

}
在这一点上，我想不出别的办法去尝试了。.任何帮助都是非常感激的

问题是您无法连接到MYSQL数据库，因此抛出错误，称无法构建会话工厂。

请查看下面的错误：

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

字符串
这表明username没有得到populated。

请重新检查系统属性

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

型
一些包似乎也丢失了，这表明存在依赖性问题：

package org.gjt.mm.mysql does not exist

型
请运行mvn dependency:tree命令以检查依赖项

即使所有相关的依赖项都已到位，我还是会得到这个错误，因为我没有在MySQL中创建模式。
我以为它会自动创建，但它不是。虽然表本身将被创建，但您必须创建模式。

我发现了一些关于这种错误的问题
1.数据库用户名或密码在mysql或其他数据库中不匹配。请这样设置application.properties

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

字符串
问题2。
您的本地服务器有两个数据库服务器，并且这些数据库服务器发生冲突。这个冲突就像这个mysql服务器和xampp或lampp或wamp服务器。请选择一个数据库，比如mysql server，因为xampp或lampp server会自动在本机上安装mysql server

由于命名查询中的错误，获得此错误。

当我尝试连接到MariaDB数据库时发生此错误

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

字符串
指定在我的application.properties。我没有设置它为任何其他值，因此使用了一个坏的驱动程序。我从我的application.properties中删除了显式的驱动程序描述，让spring自己决定使用哪个驱动程序。这为我解决了这个问题。
