Problem:

I have read many posts on andromda forum about How to obtain Hibernat sessionFactory and I tried two approaches which ddn't work with me then I make some solution wihch I don't know if it is dirty solution or not but at least it works with me so I guess it is not ;)

the following approaches I tried to apply them inside the ServiceImpl

first I tried the following approach:

­­org.hibernate.Session session = 
  org.springframework.orm.hibernate3.SessionFactoryUtils.getSession(
   (org.hibernate.SessionFactory)S­erviceLocator.instance().getService("sessionFactory"), true);

and it didn't work with me.

then I followed the following approach:

­HibernateInterceptor hibernateInterceptor = 
   (HibernateInterceptor) ServiceLocator.instance().getService("hibernateInterceptor");

SessionFactory sessionFactory = hibernateInterceptor.getSessionFactory();
Session session = sessionFactory.getCurrentSession();­          

and it didn't work with me also.

­

and both approaches fails and throw MyServiceException from it. when it reaches the execution of the following line

­­­­ this.beanFactoryReference = ­­beanFactoryLocator.useBeanFactory(this.beanRefFactoryReferenceId);

from inside the ServiceLocator Class from

protected synchronized org.springframework.context.ApplicationContext getContext()

method

Solution:

as I said above I need to make sessionFactory available in the services so I did the following:

first extracted the andromda-spring-cartrige which is located under the following path

Quote:

$M2_HOME/repository/org/andromda/cartridges/andromda-spring-cartridge/3.3-SNAPSHOT



and copied the template directory to my

Quote:

project/mda/src/main/config/cartridge

folder

then I created SpringTemplateMergeMappings.xml file under

Quote:

project/mda/src/main/config/mappings

which contains the following mapping

­Code: <mappings name="SpringTemplateMerge"> <mapping> <from><![CDATA[<!-- cartridge-template merge-point -->]]></from>         <to>         <![CDATA[                <template path="templates/spring/applicationContext.xml.vsl"                outputPattern="$applicationContext"                outlet="spring-configuration"                  overwrite="true" outputToSingleFile="true"                  outputOnEmptyElements="false"> <modelElements>                         <modelElement variable="entities">                                 <type name="org.andromda.cartridges.spring.metafacades.SpringEntity"/>                         </modelElement>                         <modelElement variable="services">                                 <type name="org.andromda.cartridges.spring.metafacades.SpringService">                                         <property name="abstract">false</property>                                 </type>                         </modelElement>                         <modelElement variable="manageables">                                 <type name="org.andromda.cartridges.spring.metafacades.SpringManageableEntity"/>                         </modelElement>                 </modelElements>         </template>                 ]]>         </to> </mapping> </mappings> ­­

then I have inserted the following two lines:

­Code: <property name="mergeLocation">${conf.dir}/cartridge</property> <property name="mergeMappingsUri"> file:${conf.dir}/mappings/SpringTemplateMergeMappings.xml </property>


inside the

Quote:

mda/src/main/config/andromda.xml

inside the spring namespace

and altered the applicationContext.vsl which is located under

Quote:

/mda/src/main/config/cartridge/template/spring/


to add the following line in the

­Code: ­­#­foreach($service in $services)     <!-- $service.name Service Proxy with inner $service.name Service Implementation -->     <bean id="$service.getBeanName(false)" class="org.springframework.aop.framework.ProxyFactoryBean"> <property name="target">             <bean class="$service.fullyQualifiedImplement­ationName"> #if ($daoRefsEnabled)­       <!-- sessionFactory being injected by -->       <property name="sessionFactory"><ref bean="sessionFactory"/></property> #foreach($entityRef in $service.allEntityReferences)       <property name="$entityRef.daoName"><ref bean="$entityRef.targetElement.getBeanName(false)"/></property> #end #end ­


<!-- ========================= Start of SERVICE DEFINITIONS ========================= --> section

at the end I have edited the ServiceBase.VSL to include the setter and getter for sessionFactory as follows

Code:

private SessionFactory sessionFactory;     /**      *      * Sets the reference to <code>sessionFactory</code>.      */     public void setSessionFactory(SessionFactory sessionFactory) {        this.sessionFactory = sessionFactory;     }     /**      *      * Gets the reference to <code>sessionFactory</code>.      */     protected SessionFactory getSessionFactory() { &nbs­p;      return this.sessionFactory;     }
