jboss - JBoss AS 7.1.1 的 Persistence.xml

Question

我有一个与 JBoss AS 7.1.1 一起运行的客户端和服务器设置，我对我的 persistence.xml 有疑问。目前它看起来像这样:

<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>

我在服务器的 META-INF 文件夹中有 persistence.xml。我一定是缺少一些属性，因为当我尝试查询连接到的数据库时遇到此错误。

11:35:07,840 ERROR [org.jboss.ejb3.invocation] (EJB default - 1) JBAS014134: 
EJB Invocation failed on component GrahamsProjBean for method public abstract 
void grahamsprojserver.session.interfaces.GrahamsProjBeanRemote.test(): javax.ejb.EJB
Exception: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: 
Schemas is not mapped [FROM Schemas s]

有什么我想念的吗？

您需要在 persistence.xml 中包含所有模型类。示例:

<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>
