java - example - EclipseLinkJpaVendorAdapter en lugar del problema HibernateJpaVendorAdapter
spring jpa hibernate (1)
De forma predeterminada, EclipseLink espera que el entrelazado en tiempo de ejecución esté habilitado; de lo contrario, recibirá un error en el formulario ''No se puede aplicar el transformador de clase sin LoadTimeWeaver especificado''. Esto significa que, para los casos que usan tejido de tiempo de construcción o ningún tejido, deberá indicar explícitamente este comportamiento. Para deshabilitar el tejido de EclipseLink, necesitará configurar el bean de primavera EntityManagerFactory de una aplicación con:
<property name="jpaPropertyMap">
<map>
<entry key="eclipselink.weaving" value="false"/>
</map>
</property>
o agregue el
<property name="eclipselink.weaving" value="false"/>
al archivo persistence.xml de su aplicación.
Recomiendo activar el tejido ya que es una gran mejora en el rendimiento.
Para configurar el weaver predeterminado en tiempo de ejecución esperado por EclipseLink, agregue lo siguiente:
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
</property>
al bean de primavera EntityManagerFactory de su aplicación.
A continuación, agregue esta opción a su JVM:
-javaagent:/path-to-your-javaagent/org.springframework.instrument-3.1.1.RELEASE.jar
En Spring 3.x el javaagent se localiza en el jarro org.springframework.instrument.
Necesita la biblioteca org.springframework.instrument junto con las bibliotecas aspectjrt.jar y aspectjweaver.jar .
Referencia
utilizando una aplicación que consta de JSF, Spring e Hibernate. Mi ejemplo se ejecuta normalmente, luego cuando cambié la clase = "org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" a class = "org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter", la aplicación no se ejecutaba normalmente. ¿Cuál es el problema? Cualquiera de ellos es la impelementación de especificación JPA.
