使用由JSF，Spring和Hibernate组成的应用程序。我的示例正常运行，然后当我将class =“ org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter”更改为class =“ org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter”时，应用程序无法正常运行。有什么问题？JPA专业化实现都是其中之一。

缺省情况下，EclipseLink期望启用运行时 编织 ，否则您将收到“没有指定LoadTimeWeaver不能应用类转换器”形式的错误。这意味着，对于使用构建时编织或根本不编织的情况，您将需要明确指出此行为。为了禁用EclipseLink编织，您将需要使用以下方法配置应用程序的EntityManagerFactory Spring bean：
<property name="jpaPropertyMap"> <map> <entry key="eclipselink.weaving" value="false"/> </map> </property>
或添加
<property name="eclipselink.weaving" value="false"/>
到应用程序的persistence.xml文件。
我建议激活编织，因为它可以极大地提高性能。
要配置EclipseLink期望的默认运行时织布工，请添加以下内容：
<property name="loadTimeWeaver"> <bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/> </property>
到应用程序的EntityManagerFactory Spring bean。
然后将此选项添加到您的JVM中：
-javaagent:/path-to-your-javaagent/org.springframework.instrument-3.1.1.RELEASE.jar
在Spring 3.x中，javaagent位于org.springframework.instrument jar中。
您需要 org.springframework.instrument 一起库 aspectjrt.jar 和 aspectjweaver.jar 库。
