我正在尝试使用 Hibernate 4 作为持久性提供程序来配置 Spring 3.2、JPA 2.0。当我尝试在 Weblogic 10.3.5 中部署应用程序时，我收到以下错误（由于大小而缩写）：

            p:showSql="true" p:databasePlatform="org.hibernate.dialect.Oracle10gDialect" />
    </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"
    p:entityManagerFactory-ref="entityManagerFactory" />

<tx:annotation-driven transaction-manager="transactionManager" />

<bean
    class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />

如您所见，我正在拉入 entitymanager jar 文件。

任何可以提供的帮助将不胜感激。

谢谢！

由于您得到 a java.lang.NoClassDefFoundError（而不是 a ClassNotFoundException），因此可能是某种类加载问题。

这通常是由于在 webapp 库 ( WEB-INF/lib) 中导入应用程序服务器中已经可用的 JAR 引起的。

在你的情况下，我怀疑hibernate-jpa-2.0-api.jar.

这里有两件事可以尝试：

  • hibernate-jpa-2.0-api.jar从您的依赖项中排除。

    或者

  • <prefer-web-inf-classes>在weblogic.xml文件中添加。

绝对是一些旧版本或未使用的休眠 jar 现在存在于您的 lib 文件夹中。我的情况是hibernate-annotations-xxxjar。

我从我的库中删除了这个 hibernate-annotations-xxxjar。

如果您使用的是 hibernate-commons-annotations-xxxjar 则无需放在 jar 之上。我遇到了同样的问题，当我删除 hibernate-annotations-xxxjar 并重新启动服务器时，我的错误就消失了。只放hibernate-commons-annotations-xxxjar。

搜索任何其他旧的休眠版本 jar，如果有，则将其删除并放入最新的。

基于此maven 存储库，不存在hibernate-entitymanager-4.2.2.Final版本。使用4.2.1.Final也我认为你需要添加其他休眠依赖项，例如hibernate-core更多关于依赖项的信息，
