Class UserDaoImpl

java.lang.Object
  org.synyx.hades.sample.dao.impl.UserDaoImpl

All Implemented Interfaces:

UserDaoCustom

public class UserDaoImpl
extends java.lang.Object
implements UserDaoCustom

Implementation fo the custom DAo functionality declared in UserDaoCustom based on JPA. To use this implementation in combination with Hades you can either register it programatically:

 EntityManager em = ... // Obtain EntityManager
 
 UserDaoCustom custom = new UserDaoImpl();
 custom.setEntityManager(em);
 
 GenericDaoFactory factory = GenericDaoFactory.create(em);
 UserDao dao = factory.getDao(UserDao.class, custom);
 

Using the Spring namespace the implementation will just get picked up due to the classpath scanning for implementations with the Impl postfix.

 <hades:dao-config base-package="org.synyx.hades.sample.dao" />
 

If you need to manually configure the custom instance see UserDaoJdbcImpl for an example.
