java - 设置entityManager的components.xml缝weblogic

Question

我在 weblogic 10.3 上使用 Seam 2.2.0 开发了一个应用程序

在我的 Components.xml 中，当我设置实体管理器时，我这样做:

<persistence:managed-persistence-context name="entityManager"
        auto-create="true" persistence-unit-jndi-name="OSSPortailDataSource" />

我的数据源在 weblogic 上的配置如下:

JNDI 名称:OSSPortailDataSource驱动程序类:oracle.jdbc.OracleDriver网址:jdbc:oracle:thin:@10.1.18.98:1522:ossi

现在，当我运行我的应用程序时，我收到此错误:

java.lang.ClassCastException: weblogic.jdbc.common.internal.RmiDataSource cannot be cast to javax.persistence.EntityManagerFactory

这是日志:

如何配置持久性才能正常工作？

谢谢。

Answer 1

我找到了解决方案:

在 Components.xml 中，添加以下属性:

<persistence:entity-manager-factory name="entityManagerFactory"
        persistence-unit-name="OSSPortail" />

它是 persistence.xml(hibernate 配置)的“链接”。

在 Components.xml 中，修改 Managed-persistence-context 属性:

<persistence:managed-persistence-context name="entityManager"
    auto-create="true" entity-manager-factory="#{entityManagerFactory}" />

只需添加entity-manager-factory属性，它是persistence:entity-manager-factory属性的名称。

最后，配置 persistence.xml 文件。我的在这里:

<persistence-unit name="OSSPortail" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>OSSPortailDataSource</jta-data-source>
    <properties>
        <property name="hibernate.dialect"
            value="org.hibernate.dialect.Oracle10gDialect" />
        <property name="hibernate.connection.driver_class"
            value="oracle.jdbc.driver.OracleDriver" />
        <property name="hibernate.hbm2ddl.auto" value="update" />
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />
        <property name="hibernate.default_schema" value="SI" />
        <property name="jboss.entity.manager.factory.jndi.name"
            value="OSSPortailDataSource" />
        <property name="hibernate.transaction.manager_lookup_class"
            value="org.hibernate.transaction.WeblogicTransactionManagerLookup" />
        <property name="hibernate.query.factory_class"
            value="org.hibernate.hql.classic.ClassicQueryTranslatorFactory" />
    </properties>
</persistence-unit>
