public class JPA
extends Object

User: WilliamZhu Date: 12-6-26 Time: 下午9:46 Since it is difficult to manager POJOS generated by JPA(Actually you can use AOP).Here we use this class to create +EntityManagerFactory+,to get +EntityManager+ which do persistence and query staff. It is also a holder of some Persistence Infos.

//find the config file InputStream inputStream = Main.class.getResourceAsStream("application_for_test.yml"); Settings settings = InternalSettingsPreparer.simplePrepareSettings(ImmutableSettings.Builder.EMPTY_SETTINGS, inputStream);

//configure ORM JPA.CSDNORMConfiguration csdnormConfiguration = new JPA.CSDNORMConfiguration("development", settings, Main.class.getClassLoader()); JPA.configure(csdnormConfiguration);

//finally load all you model JPA.loadModels();

//then you can use you pojo now Tag.findAll();
