EJPAJava的ORM框架

EJPA (Easier Java Persistence API) 是一個基于 Annotation ，無配置的 ORM 框架。

示例代碼：

public static void main(String[] args)

  {

    DatabaseManager dbm = DatabaseManager.getDatabaseManager(…);

    dbm.saveObject(new Customer("smith", "John"));

    Customer customer = new Customer(“Smith”);

    if ((customer = dbm.loadObject(customer)) != null)

      {

        customer.getSupport().add(new Support(…));

        dbm.saveObject(customer);

      }

    Collection<Customer> list = new ArrayList<Customer>();

    list = dbm.loadObjects(list, Customer.class);

    …

  }
