EclipseLinkJpaVendorAdapter zamiast HibernateJpaVendorAdapter wydanie

Question

przy użyciu aplikacji składającej się z JSF, Spring i Hibernate. Mój przykład działa normalnie, a po zmianie klasy = "org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" na class = "org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter" aplikacja nie działała normalnie. Jaki jest problem? Każda z nich jest impelementacją WSPA.

Answer 1

Domyślnie EclipseLink oczekuje run-time tkackie być włączona, w przeciwnym razie zostanie wyświetlony komunikat o błędzie w postaci 'nie można zastosować transformator klasy bez LoadTimeWeaver określony'. Oznacza to, że w przypadkach, w których używa się tkania w czasie kompilacji lub w ogóle nie używa tkania, konieczne jest wyraźne wskazanie tego zachowania. W celu wyłączenia EclipseLink tkania trzeba będzie albo skonfigurowanie aplikacji EntityManagerFactory Wiosna Bean z:

<property name="jpaPropertyMap"> 
    <map> 
    <entry key="eclipselink.weaving" value="false"/> 
    </map> 
</property> 

lub dodać

<property name="eclipselink.weaving" value="false"/> 

do pliku persistence.xml danej aplikacji.

Polecam aktywować tkactwo, ponieważ poprawia to znacznie wydajność.

Aby skonfigurować domyślny run-time tkacz oczekiwany przez EclipseLink, dodać następujące:

<property name="loadTimeWeaver"> 
    <bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/> 
</property> 

do aplikacji za EntityManagerFactory wiosennym fasoli.

Następnie dodać tę opcję do JVM:

-javaagent:/path-to-your-javaagent/org.springframework.instrument-3.1.1.RELEASE.jar 

Wiosną 3.x javaagent jest zlokalizowana w słoiku org.springframework.instrument.

Trzeba bibliotekę org.springframework.instrument wraz z aspectjrt.jar i aspectjweaver.jar bibliotek.
