hbm2ddlのアップデートで春の起動時にエラーが発生しました

Question

Oracleデータベースにデータを永続化するために、エンティティ・マネージャを使用したスプリング・ブート・アプリケーションを使用しています。

hibernate.dialect: org.hibernate.dialect.Oracle9iDialect 
hibernate.show_sql: true 
hibernate.hbm2ddl.auto: update 
entitymanager.packagesToScan: com.abc.xyz 

@Bean 
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() { 
    LocalContainerEntityManagerFactoryBean entityManagerFactory = 
     new LocalContainerEntityManagerFactoryBean(); 
    entityManagerFactory.setDataSource(dataSource); 
    entityManagerFactory.setPackagesToScan(env.getProperty("entitymanager.packagesToScan")); 
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter(); 
    entityManagerFactory.setJpaVendorAdapter(vendorAdapter); 
    Properties additionalProperties = new Properties(); 
    additionalProperties.put("hibernate.dialect", env.getProperty("hibernate.dialect")); 
    additionalProperties.put("hibernate.show_sql", env.getProperty("hibernate.show_sql")); 
    additionalProperties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto")); 
    entityManagerFactory.setJpaProperties(additionalProperties); 
    return entityManagerFactory; 
    } 

Iからhbm2ddlオートを変更した場合、私は次のようなエラー

を取得していますが、次のように私の設定ファイルは、Beanが含まれているが、次のように私のapplication.propertiesがあります更新をcreate-dropにするとうまくいきますが、テーブルを削除して作成します。

Answer 1

を助けてください。私はojdbc7でoracle 9iを使用していましたが、問題を解決したojdbc6に変更しました。

ojdbc7はoracle 9iをサポートしていません。
