JBoss AS 7.1.1的Persistence.xml

我有一个客户机和服务器设置要用JBossAS 7.1.1运行，我对persistence.xml有一个问题。现在看起来是这样的：

<persistence>
    <persistence-unit name="GrahamsProj">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:jboss/datasources/WorkCenterDS</jta-data-source>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
        </properties>
    </persistence-unit>
</persistence>

我缺少什么吗？

您需要在persistence.xml中包含所有模型类。例如：

<persistence>
    <persistence-unit name="GrahamsProj">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:jboss/datasources/WorkCenterDS</jta-data-source>
        <class>your.class.model.Example</class>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
        </properties>
    </persistence-unit>
</persistence>

org.hibernate.ejb.HibernatePersistence
java:jboss/datasources/WorkCenterDS
你的.class.model.Example

您可能还需要更新hibernate.dial属性。在您的示例中，您使用的是“org.hibernate.dialogue.hsqldiante”，您使用的是Oracle驱动程序，例如“Oracle.jdbc.OracleDriver”。如果您使用的是Oracle数据库，则需要更新hibernate方言，例如“org.hibernate.dialogue.Oracle10gDialogue”

以下是您的更新代码：

<persistence>
    <persistence-unit name="GrahamsProj">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:jboss/datasources/WorkCenterDS</jta-data-source>
        <class>your.class.model.Example</class>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
        </properties>
    </persistence-unit>
</persistence>

org.hibernate.ejb.HibernatePersistence
java:jboss/datasources/WorkCenterDS
你的.class.model.Example

<persistence>
    <persistence-unit name="GrahamsProj">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:jboss/datasources/WorkCenterDS</jta-data-source>
        <class>your.class.model.Example</class>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
        </properties>
    </persistence-unit>
</persistence>
