无法使用 Hibernate 在 spring-boot 应用程序中访问 HSQLDB 数据库

Question

在我当前的 spring-boot 应用程序中，我正在尝试使用 hibernate 来访问 HSQLDB 数据库。我有这个用于休眠的配置类：

@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.spring.app" })
public class HibernateConfig {

   @Bean
   public LocalSessionFactoryBean sessionFactory() {
      LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

      sessionFactory.setDataSource(restDataSource());
      sessionFactory.setPackagesToScan(new String[] { "com.spring.app.model" });
      sessionFactory.setHibernateProperties(hibernateProperties());

      return sessionFactory;
   }

   @Bean
   public DataSource restDataSource() {
      BasicDataSource dataSource = new BasicDataSource();
      String db_url = System.getProperty("user.home")+File.separator+"testedb";

      dataSource.setDriverClassName("org.hsqldb.jdbcDriver");
      dataSource.setUrl("jdbc:hsqldb:file:"+db_url);
      dataSource.setUsername("sa");
      dataSource.setPassword("");

      return dataSource;
   }

   @Bean
   @Autowired
   public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) {
      HibernateTransactionManager txManager = new HibernateTransactionManager();
      txManager.setSessionFactory(sessionFactory);
      return txManager;
   }

   @Bean
   public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
      return new PersistenceExceptionTranslationPostProcessor();
   }

   Properties hibernateProperties() {
      return new Properties() {
         /**
         * 
         */
        private static final long serialVersionUID = 1L;

        {
            setProperty("hibernate.hbm2ddl.auto", "create");
            setProperty("hibernate.hbm2ddl.import_files", "import.sql");
            setProperty("hibernate.show_sql", "false");
            setProperty("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
         }
      };
   }
}

但是当我运行应用程序时，当我应该导出数据库方案时，我会在控制台中看到这条消息：

我尝试同时使用sa 或SA 作为用户名，但没有成功。另外，我的类路径中有这个import.sql 文件：

INSERT INTO role VALUES (1, 'admin');
INSERT INTO permission VALUES (1, 'admin');
INSERT INTO role_permissions VALUES (1,1);
INSERT INTO usuario VALUES (1, 'klebermo', 'pwd', 'Kleber', 'Mota', 'kleber@mail');
INSERT INTO role_members VALUES (1,1);

但没有在数据库中插入数据（当我尝试登录应用程序时，我收到一条消息“找不到用户”。

我在这里做错了什么？

我同意博胡斯拉夫的观点。如果有帮助，我只需在 application.properties 中添加以下内容即可配置对 MySQL 的访问：

#
## Database configuration
#
spring.datasource.url: jdbc:mysql://localhost:3306/spring
spring.datasource.username: spring
spring.datasource.password: spring
spring.datasource.driverClassName: com.mysql.jdbc.Driver

spring.jpa.hibernate.ddl-auto: update
spring.jpa.database: MYSQL
#spring.jpa.hibernate.naming_strategy: org.hibernate.cfg.ImprovedNamingStrategy
#spring.jpa.show-sql: true
