EclipseLinkJpaVendorAdapter au lieu de HibernateJpaVendorAdapter problème
En utilisant une application composée de JSF, Spring et Hibernate. Mon exemple fonctionne normalement, puis quand j'ai changé la classe = " org.springframework.orm.jpa.Fournisseur.HibernateJpaVendorAdapter "à class =" org.springframework.orm.jpa.Fournisseur.EclipseLinkJpaVendorAdapter", l'application n'a pas fonctionné normalement. Quel est le problème? L'un d'eux sont JPA spesificition impelementation.

Par défaut, EclipseLink s'attend à ce que l'exécution tissage soit activée, sinon vous recevrez une erreur sous la forme 'impossible d'appliquer le transformateur de classe sans loadtimeweaver spécifié'. Cela signifie que pour les cas utilisant le tissage au moment de la construction ou aucun tissage du tout, vous devrez indiquer explicitement ce comportement. Pour désactiver le tissage EclipseLink, vous devez soit configurer le bean de printemps EntityManagerFactory d'une application avec:
<property name="jpaPropertyMap">
<map>
<entry key="eclipselink.weaving" value="false"/>
</map>
</property>
Ou ajouter le
<property name="eclipselink.weaving" value="false"/>
À la persistance de votre application.fichier xml.
Je recommande d'activer le tissage car c'est une grande amélioration des performances.
Pour configurer le weaver d'exécution par défaut attendu par EclipseLink, ajoutez ce qui suit:
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
</property>
À EntityManagerFactory Spring bean de votre application.
Ajoutez ensuite cette option à votre JVM:
-javaagent:/path-to-your-javaagent/org.springframework.instrument-3.1.1.RELEASE.jar
Au Printemps 3.x le javaagent est localisé dans l'organisation.springframework.instrument jar.
Vous avez besoin le org.springframework.instrument bibliothèque avec aspectjrt.jar et aspectjweaver.jar bibliothèques.
