JSF, İlkbahar ve Hazırda Bekletme durumundan oluşan bir uygulama kullanarak HibernateJpaVendorAdapter sorunu yerine

Question

EclipseLinkJpaVendorAdapter. Örneğim normal olarak çalışıyor, sonra class = "org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" sınıfını class = "org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter" olarak değiştirdiğimde, uygulama normal şekilde çalışmadı. Sorun ne? Bunlardan her biri JPA spesifisit impelementasyonu.

Answer 1

, EclipseLink beklediğini çalışma zamanı dokuma aksi takdirde formda bir hata alırsınız, etkin olmasını 'LoadTimeWeaver belirtilen olmadan sınıf trafo uygulanamıyor'. Bu, yapı-zaman dokuması kullanan veya hiç dokuma yapmayan durumlarda, bu davranışı açıkça belirtmeniz gerektiği anlamına gelir.

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

veya uygulamanızın persistence.xml dosyasına

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

ekleyin: Eğer bir uygulamanın EntityManagerFactory Bahar fasulye yapılandırmak ya da olması gerekir dokuma EclipseLink devre dışı bırakmak amacıyla.

Performansı büyük ölçüde iyileştirdiğinden, dokumayı etkinleştirmenizi tavsiye ederim.

aşağıdakileri ekleyin, EclipseLink beklediği varsayılan çalışma zamanı dokumacı yapılandırmak için: uygulamanızın EntityManagerFactory Bahar fasulye için

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

.

Sonra JVM'nize için bu seçeneği ekleyin: Bahar ayında

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

javaagent org.springframework.instrument kavanozda lokalize edilir 3.x.

Sen aspectjweaver.jar aspectjrt.jar ve kütüphanelerle birlikte org.springframework.instrument kitaplık gerekir.
