Hibernate Annotations and Spring

[musch]

Hello

How can I use Hibernate Annotations with Spring ?

I think that Spring have some configuration for it.
today I use to:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
   <property name="mappingResources">
      <list>
         <value>com/model/MyModel.hbm.xml</value>
      </list>
   </property>
   .
   .
   .

and with Annotations, How Can I do ?

I saw your Thread in http://forum.springframework.org/showthread.php?t=13796, I wrote the AnnotationSessionFactoryBean and change my Spring configurations, but now, I'm geting a error in my application startup, see my config files and the ERROR.

import java.util.List;
import org.hibernate.HibernateException;
import org.hibernate.MappingException;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;
import org.springframework.context.ApplicationContextException;
import org.springframework.orm.hibernate3.LocalSessionFactoryBean;

public class AnnotationSessionFactoryBean extends LocalSessionFactoryBean {

    private static final Logger LOG = Logger.getLogger(AnnotationSessionFactoryBean.class); 

    private List<String> annotatedClasses_; 
    
    /** 
     * @return the classes. 
     */ 
    public List getAnnotatedClasses() { 
        return annotatedClasses_; 
    } 
    
    /** 
     * @param classes The classes to set. 
     */ 
    public void setAnnotatedClasses(List<String> classes) {
        annotatedClasses_ = classes; 
    } 

    @Override 
    protected void postProcessConfiguration(Configuration config) throws HibernateException { 
        super.postProcessConfiguration(config); 

        if (!(config instanceof AnnotationConfiguration)) { 
            throw new ApplicationContextException("The configuration must be AnnotationConfiguration."); 
        } 

        if (annotatedClasses_ == null) { 
            LOG.info("No annotated classes to register with Hibernate."); 
            return; 
        } 

        for (String className : annotatedClasses_) {
            try { 
                Class clazz = config.getClass().getClassLoader().loadClass(className); 
                ((AnnotationConfiguration)config).addAnnotatedClass(clazz); 

                if (LOG.isDebugEnabled()) { 
                    LOG.debug("Class " + className + " added to Hibernate config."); 
                } 
            } 
            catch (MappingException e) { 
                throw new ApplicationContextException("Unable to register class " + className, e); 
            } 
            catch (ClassNotFoundException e) { 
                throw new ApplicationContextException("Unable to register class " + className, e); 
            } 
        }

try set this property to your session factory bean:
<property name="configClass"><value>org.hibernate.cfg.Annota tionConfiguration</value></property>

BTW, if you are already using a separate hibernate.cfg.xml, you don't need to bother with AnnotationSessionFactoryBean. The Hibernate Annotations package has built-in support for adding annotated classes through hibernate.cfg.xml. AnnotationSessionFactoryBean only makes sense if you want to keep everything in spring bean definitions.

very tks buddy, now my application work with hibernate annotations, but a observation, the right is :

<property name="configurationClass">
   <value>org.hibernate.cfg.AnnotationConfiguration</value>
</property>

and not configClass

thanks for posting your solution.
I had a similar problem.
