我的persistence.xml 中有两个持久性单元，一个是XA，另一个是非xa（以在工作仅与单个数据源相关且我不需要全局事务时提高性能）。

<persistence-unit name="pu-negin88" transaction-type="JTA">
    <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
    <jta-data-source>jdbc/glDS</jta-data-source>
    <non-jta-data-source>jdbc/glDS</non-jta-data-source>
</persistence-unit>

<persistence-unit name="pu-nonxa" transaction-type="JTA">
    <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
    <jta-data-source>jdbc/bancononxaDS</jta-data-source>
</persistence-unit>

我将 XA 持久性单元加载的对象传递给无状态会话 bean 中的方法，该方法使用非 xa 持久性单元并需要新事务。在此会话 bean 中，我使用此对象的一些属性从 DD 加载其他对象，此时，我收到以下异常：

javax.ejb.AccessLocalException: Client not authorized for this invocation.

（当工作仅与单个数据源相关并且我不需要全局事务时提高性能）。

首先，您是否实际测量过这会提高性能？作为一般规则，当只有 1 个事务资源参与事务时，事务提供程序会自动优化。

对于实际的异常，也许您应该显示您实际使用的代码。我想知道用于通过 XA 持久性单元加载实体的事务是否已经结束。

如果交易已经结束，你的实体将被分离，没有人会再记得它最初来自哪里。由于您所说的另一个无状态会话 bean 需要一个新事务，因此您有一种嵌套事务形式，如果延迟加载实体的属性，这可能是问题。

通常，anAccessLocalException实际上更能说明安全问题，例如，当两个 bean 位于不同的安全领域和/或@RolesAllowed在它们上定义了安全主体（调用者）没有的安全问题时。

我解决了这个问题，现在我没有这个例外。这是因为第一个持久化单元加载的对象在第二个持久化单元中是非托管的，当我想使用该对象时，抛出了这个异常。我使用了 getReference() 方法并从主对象创建了一个空心对象并完成了我的工作。
