Interface IEntityManagerFactoryProvider

  • All Known Implementing Classes:
    EntityManagerFactoryProvider
    public interface IEntityManagerFactoryProvider
    Interface for creating the JPA EntityManagerFactory instances used by OpenXava.

    This is part of a Factory pattern implementation for EntityManagerFactory creation for your application, which allows extending or replacing the default mechanism without modifying OpenXava core code.

    The pattern consists of:

    1. This interface (IEntityManagerFactoryProvider)
    2. A default implementation (EntityManagerFactoryProvider)

    To create a custom provider, extend EntityManagerFactoryProvider or implement this interface directly.

    To use your custom provider, add the following line to your application's xava.properties file: 

     entityManagerFactoryProviderClass=com.yourcompany.yourapp.jpa.impl.MyEntityManagerFactoryProvider

    Example: 

     // EntityManagerFactoryProvider is the default implementation 
 // and implements IEntityManagerFactoryProvider
 public class MyEntityManagerFactoryProvider extends EntityManagerFactoryProvider {
