copied!<p>I'd start to observe the following:</p> <ul> <li>You have a <code>GenericDao<T></code> which means that you can have different implementations.</li> <li>Currently, you have <code>GenericDaoImpl<T> extends JdbcDaoSupport</code> which means that you cannot use in the other environment you described without any application context unless you prepare all the object in a manual fashion.</li> </ul> <p>So my suggestion is:</p> <ul> <li>Allow <code>GenericDao<T> extends org.springframework.jdbc.core.JdbcOperations</code></li> <li>Develop an <code>AbstractGenericDao<T> implements GenericDao<T></code> to bring the abstract general functionality you need.</li> <li>Develop a <code>MyEnvGenericDao<T> extends AbstractGenericDao<T></code> that is responsible to provide a <em>data source</em> and underlying implementation of different methods you need; could be using a direct Hibernate/OpenJPA implementation to directly executing the queries.</li> <li>Develop a <code>SpringGenericDao<T> extends JdbcDaoSupport implements GenericDao<T></code> that comes is already with a <code>getJdbcTemplate()</code> to perform the operations you need and is delegated to Spring JDBC template. In this scenario, you need to delegate the operations to <code>JdbcDaoSupport.getJdbcTemplate()</code>.</li> </ul> <p>Related to Maven, then you can actually have different modules for <code>MyEnv</code> and <code>Spring</code> implementations but both with one parent to have access to <code>GenericDao<T></code> interface.</p>
