Ahoj, také používám oba přístupy a konfiguraci mám takto.
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactor
yBean">
<property name="dataSource" ref="dataSource"/>
<property name="annotatedClasses">

<property name="mappingLocations">

Subject: Spring + hibernate + annotations
Ahojte,
pouzival jsem pro hibernate vzdy xml soubory a vse fungovalo jak jsem
potreboval. Ted se snazim prejit na annotace a mam problem s tim ze mi
pri
dotazech pise NullPointerException. Pritom session factory neni null,
criteria taky ne a session taktez ne.
Pouzivam v soucasne dobe hibridni pristup. Tedy mam jednu
hibernateSessionFactory pro annotace, druhou mam pro klasickou
konfiguraci
pres xml. Soubor s anotovanym objektem mi normalne najde. Tam zadny
problem neni. Jenom kdyz zjistuju pocet objektu v kolekci.
konfigurace springu:
<!-- hibernate OR mapping -->
<bean id="hibernateSessionFactory4Annotations"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="myDataSourceAnnotations" />
<property name="configurationClass"
value="org.hibernate.cfg.AnnotationConfiguration"/>
<property name="configLocation"
value="classpath:mappings/hibernate.annotations.cfg.xml"/>
<property name="hibernateProperties">
<props>
<prop
key="hibernate.bytecode.provider">javassist</prop>
<prop key="hibernate.show_sql">true</prop>
<prop
key="hibernate.cache.use_second_level_cache">false</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
v souboru hibernate.annotations.cfg.xml je nasledujici radek:
<?xml version="1.0"?>
<!DOCTYPE hibernate-configuration PUBLIC

Chyba kterou mi to hlasi pri inicializaci do logu - ten posledni radek.
Pritom ty anotace projde.:

Kdyz napisu do toho souboru hibernate.annotations.cfg.xml nazev
annotovane
tridy spatne, tak mi to vyhlasi ze neexistuje. Takze zjevne tu tridu
najde. Akorat je divne ze pak nenapise jako pri klasicke inicializaci
pomoci xml neco ve stylu:
2007-11-21 12:46:59,221 INFO [org.hibernate.cfg.HbmBinder] - <Mapping
class: net.itsynapse2.ecomerce.entity.article.Article ->
ecomerce_article>
Problem je pak kdyz chci nejake radky pomoci criteria dostat tak mi to
vyhlasi NullPointerException. Za jakoukoliv radu budu moc rad.
