我在 github 上编写了一个简单的 tcp 入站资源适配器 (RA) 作为示例项目，并将其成功部署到具有独立完整配置的 Wildfly 10.x。消息侦听TcpMessageListener器接口位于 RA 中并在 ra.xml 描述符中定义，但我无法将消息驱动 bean (MDB) 连接到它。RA 的 eis 端按预期工作，我可以使用 telnet 向其连接/发送消息。当我尝试使用 wildfly maven 插件部署 MDB 时，MDB 找不到TcpMessageListener，我得到了java.lang.NoClassDefFoundError：

ejb maven 子模块中的依赖关系在provided范围内。我跟着redhat指南的RA部署。我还在 ejb 子模块中切换了资源适配器的 maven 依赖项，从提供到编译。在这种情况下，我收到以下错误
[ERROR] Caused by: java.lang.IllegalStateException: WFLYEJB0383: No message listener of type de.bitc.jca.inflow.TcpMessageListener found in resource adapter tcp-eis.rar"},

这是MDB
package de.bitc.ejb;
import java.util.logging.Logger;
import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import org.jboss.ejb3.annotation.ResourceAdapter;
import de.bitc.jca.inflow.TcpMessageListener;
@MessageDriven(
activationConfig = {
@ActivationConfigProperty(propertyName = "topic", propertyValue = "test")
} //, messageListenerInterface = TcpMessageListener.class
)
@ResourceAdapter(value="tcp-eis.rar")
public class InboundEventHandler implements TcpMessageListener {
/** The logger */
private static Logger log = Logger.getLogger(InboundEventHandler.class.getName());
/**
* Default constructor.
*/
public InboundEventHandler() {
// TODO Auto-generated constructor stub
}
/**
* @see TcpMessageListener#onMessage(String)
*/
@Override
public void onMessage(String msg) {
// TODO Auto-generated method stub
}
}
这是 TcpListenerInterface
package de.bitc.jca.inflow;
/**
* TcpMessageListener
*
* @version $Revision: $
*/
public interface TcpMessageListener {
/**
* Receive message
*
* @param msg
* String.
*/
public void onMessage(String msg);
}
这是jboss_cli中资源适配器的设置

我的问题是，MDB 找到资源适配器的部署中是否缺少步骤。我认为这是通过@ResourceAdapter注释完成的？我需要定义一个队列还是什么？关于入站资源适配器的资源非常少见，最多的例子是出站资源适配器。提前致谢。
上面链接的 inbound-ra-example 托管在 github 上。我在 github 项目的 README.md 中描述了构建和运行它的所有步骤。我想为其他有相同问题的人提供这些示例以查找文档。
