Jms 为什么'；Wildfly是否允许我的应用程序访问org.Hornetq（Hornetq&x27；的API）？

我真的需要帮助

我有一个简单的Java客户机（由Eclipse在容器外部运行）。 我在本地主机上运行了Wildfly 9。 我在Wildfly上部署了一个简单的MDB作为ear包

客户端对“jms/RemoteConnectionFactory”执行JNDI查找 它使用了HornetQJMSConnectionFactory。 它向MDB侦听的队列发送ObjectMessage

MDB的onMessage（Message msg）显示它接收消息。 msg是HornetQoObjectMessage的一个实例。 但是，当我尝试向HornetQoObjectMessage投射msg以便检索对象时，它失败了

核心错误似乎是HornetQoObjectMessage的NoClassDefFoundError，因此我的应用程序无法访问HornetQAPI（我想是org.HornetQ模块）

注意：强制转换在try-catch块中，但是没有从my-catch块输出到Wildfly日志

我已经在下面粘贴了MDB代码

My module.xml

并从Wildfly日志中提取相关行。 很明显，这条信息已经到了。请参阅带有“XXXXXXXXX”前缀的行。 然后失败

ear没有war模块

注意：我添加@ApplicationScoped只是因为有人建议它解决我之前发布的一个问题。这是我现在的问题吗

请帮忙

MDB代码：

@MessageDriven(  
    activationConfig ={  
      @ActivationConfigProperty(propertyName="destinationType", propertyValue="javax.jms.Queue"),  
      @ActivationConfigProperty(propertyName="maxSession",propertyValue="1"),  
      @ActivationConfigProperty(propertyName="destination", propertyValue="jms/goSendToServerQueue")
    }) 

public class GoMsgBean implements MessageListener {

  @ApplicationScoped

  @Inject
  @JMSConnectionFactory ("java:jboss/DefaultJMSConnectionFactory")
  private JMSContext jmsCtx;

  @Resource(name = "java:jboss/exported/jms/goSendToClientQueue")  
  private Queue sendToClientQueue; 

  public GoMsgBean () {
  }

  @PostConstruct
  public void myInit () {
    System.out.println("XXXXXXXXXX Post Construct - GoMsgBean");
  }
  @PreDestroy
  public void myDestroy () {
    System.out.println("XXXXXXXXXX Post Destroy - GoMsgBean");
  }


  public void onMessage(Message msg) {
    System.out.println("XXXXXXXXXX Greetings From GoMsgBean.onMessage()");
    System.out.println("XXXXXXXXXX Message Type is " + msg.getClass().getSimpleName());
    try {
      HornetQObjectMessage oMsg = (HornetQObjectMessage) msg;
      System.out.println("XXXXXXXXXX Successfully Cast msg to HornetQObjectMessage");
      System.out.println("XXXXXXXXXX Object Type is " + oMsg.getObject().getClass().getSimpleName());
    } catch (ClassCastException e) {
      System.out.println("XXXXXXXXXX ClassCastException");
    } catch (JMSException e) {
      System.out.println("XXXXXXXXXX JMSException ");
    } catch (Exception e) {
      System.out.println("XXXXXXXXXX " + e.getClass().getSimpleName()");
    }
  }
}

MODULE.XML

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.acmemq">
    <dependencies>
       <!-- we depend on org.hornetq module since we will send messages to  -->
       <!-- the HornetQ server embedded in the local WildFly instance       -->
       <module name="org.hornetq" />
    </dependencies>
</module>

HornetQ是JMS API的一个实现细节，您不应该依赖它，而应该“只”使用API本身。您应该将其强制转换为“ObjectMessage”。顺便说一下，在使用ObjectMessage；）之前，您可以先看一下谢谢似乎我的客户机的JNDI查找“jms/RemoteConnectionFactory”生成了一个HornetQoObjectConnectionFatory，其会话最终将HornetQoObjectMessage发送到我的MDB的onMessage（Message msg）方法。尝试将消息强制转换为ObjectMessage时出错。完全违背直觉，但我已经被迫从玻璃鱼到野蝇，所以也许我在其他地方做了一些事情来获得野蝇的联系，把事情搞砸了。将在本周末从头开始重做客户端，以查看是否可以发送一条普通的旧ObjectMessage。下周我会让每个人都知道。也许你的war/ear中有jms.jar，这会与服务器上的jms.jar冲突。
