java - EclipseLinkJpaVendorAdapter 而不是 HibernateJpaVendorAdapter 问题

使用由 JSF、Spring 和 Hibernate 组成的应用程序。我的示例运行正常,然后当我将 class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"更改为 class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"时,应用程序没有正常运行。有什么问题?它们中的任何一个都是 JPA 规范实现。

最佳答案

默认情况下,EclipseLink 期望启用运行时编织,否则您将收到“无法在未指定 LoadTimeWeaver 的情况下应用类转换器”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,您需要明确指出此行为。为了禁用 EclipseLink 编织,您需要配置应用程序的 EntityManagerFactory Spring bean:

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

或添加

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

到您的应用程序的 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 预期的默认运行时编织器,请添加以下内容:

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

到您的应用程序的 EntityManagerFactory Spring bean。

然后将此选项添加到您的 JVM:

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

在 Spring 3.x 中,javaagent 本地化在 org.springframework.instrument jar 中。

您需要 org.springframework.instrument 库以及 aspectjrt.jaraspectjweaver.jar 库。
