configuration inheritance

[phanhngocdi]

Hi,
supposed that, in the normal xml configuration file, i have:

<bean id="hibernateSessionFactory" class=".....LocalSessionFactoryBean"
		lazy-init="true">
		<property name="mappingResources">
					<ref bean="somelist" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">${jdbc.dialect}</prop>
				<prop key="hibernate.show_sql">${hibernate.show_sql}</prop> 
				<prop key="hibernate.default_schema" >${jdbc.schema}</prop>
				<prop key="hibernate.jdbc.batch_size" >20</prop>
				<prop key="hibernate.cache.use_second_level_cache" >${hibernate.cache.use_second_level_cache}</prop>
				<prop key="hibernate.cache.provider_class">${hibernate.cache.provider_class}</prop>
				<prop key="hibernate.cache.use_query_cache" >${hibernate.cache.use_query_cache}</prop>
				<prop key="hibernate.cache.provider_configuration_file_resource_path=">ehcache.xml</prop>
				<!-- prop key="hibernate.hbm2ddl.auto">create-drop</prop -->
			</props>
		</property>
		<property name="dataSource">
			<ref bean="${data.source}" />
		</property>
		<property name="lobHandler">
			<bean
				class="org.springframework.jdbc.support.lob.OracleLobHandler" />
		</property>
		<property name="entityInterceptor"><ref local="hibernateEntityInterceptor" /></property>
		<property name="interceptorFilter" ref="interceptorFilter" />
	</bean>

<bean id="templateHibernateDAO" lazy-init="true">
		<property name="sessionFactory">
			<ref local="hibernateSessionFactory" />
		</property>
		<property name="maxResults" value="1000"/>
	</bean>
...

<bean id="DAO1"
		class="..."
		parent="templateHibernateDAO">

	</bean>

As you can see, DAO1's configuration inherit from templateHibernateDAO.

however, i would like to configure all the beans above by javaconfig. here is my configuration

@Configurable
@PropertiesValueSource(locations = "classpath:db/environment.properties")
public abstract class AppCoreConfig {
@Bean
	public LocalSessionFactoryBean hibernateSessionFactory(){
		LocalSessionFactoryBean localSessionFactoryBean = new LocalSessionFactoryBean();
		localSessionFactoryBean.setMappingResources(getMappingResources());
		localSessionFactoryBean.setHibernateProperties(getHibernateProperties());
		localSessionFactoryBean.setDataSource(getBasicDataSource());
		localSessionFactoryBean.setLobHandler(new OracleLobHandler());
		
		//TODO: if we want to put an ADVICE, should put here
		
		return localSessionFactoryBean;
	}
	
}
...

my problem:
in java configuration, i cant create a bean similar to the bean "templateHibernateDAO" in normal xml config. i find out that javaConfig does not support configuration inheritance. is there any way to support the config inheritance in javaConfig?
please help me, thanks in advance

normal xml configuration:

<bean id="templateHibernateDAO" lazy-init="true">
<property name="sessionFactory">
<ref local="hibernateSessionFactory" />
</property>
<property name="maxResults" value="1000"/>
</bean>

<bean id="DAO1" class="..."	parent="templateHibernateDAO">
...
</bean>

as you can see, the bean "DAO1" inherits the configuration from bean "templateHibernateDAO". we call it inheritance configuration

however, in Spring JavaConfig, i could not find any example or document mention about this kind of configuration. please help me!
i propose a solution for this. In my Appconfig.java

@Bean 
public ClientDAO clientDAO(){
ClientDAO client = new ClientDAO();
setup(client);
...
return client;
}

private void setUp(HibernateDAO dao){		
dao.setSessionFactory((SessionFactory)hibernateSessionFactory().getObject());		
}

ClientDAO extends HibernateDAO

what do you think for this? pls pls
