Question

我正在尝试将我的网络应用程序部署到Heroku。我已将Hibernates（作为持久性提供程序）配置为执行以下操作：

基于实体创建架构;
从sql脚本填充数据;

这是我的配置：

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
    entityManagerFactoryBean.setDataSource(getDataSource());
    entityManagerFactoryBean.setPackagesToScan("model");
    entityManagerFactoryBean.setPersistenceProvider(new HibernatePersistenceProvider());
    entityManagerFactoryBean.setJpaProperties(getHibernateProperties());
    return entityManagerFactoryBean;
}

@Bean
public JpaTransactionManager transactionManager() {
    JpaTransactionManager transactionManager = new JpaTransactionManager();
    transactionManager.setDataSource(getDataSource());
    return transactionManager;
}

@Bean
public DataSource getDataSource() {
    String dbUrl = System.getenv("JDBC_DATABASE_URL");
    String username = System.getenv("JDBC_DATABASE_USERNAME");
    String password = System.getenv("JDBC_DATABASE_PASSWORD");

    BasicDataSource basicDataSource = new BasicDataSource();
    basicDataSource.setUrl(dbUrl);
    basicDataSource.setUsername(username);
    basicDataSource.setPassword(password);
    return basicDataSource;
}


private Properties getHibernateProperties() {
    Properties properties = new Properties();
    properties.setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
    properties.setProperty("hibernate.hbm2ddl.auto", "create-drop");
    properties.setProperty("hibernate.hbm2ddl.import_files", "test_data.sql");
    return properties;
}

然而，似乎Hibernate无法改变现有的Heroku架构：

2016-07-16T15:04:20.978399+00:00 app[web.1]: 2016-07-16 15:04:20 ERROR SchemaExport:483 - HHH000389: Unsuccessful: alter table fueling drop constraint fuel_type

你能告诉我我做错了吗？
