Spring + hibernate + annotations

Wed, 21 Nov 2007 03:53:09 -0800 

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
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd";>
<hibernate-configuration>
    <session-factory>
        <mapping class="net.itsynapse2.ecomerce.entity.bank.BankTransfer"/>
    </session-factory>
</hibernate-configuration>

Anotovany objekt:

    protected long transferId = 0;                              // cislo

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



2007-11-21 12:25:29,887 INFO [org.hibernate.cfg.annotations.Version] -

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.
