我在github上編寫了一個簡單的tcp入站資源適配器（RA），作爲example project，併成功將其部署到wildfly 10.x，其中包含standalone-full組態。消息監聽器TcpMessageListener接口位於RA中，並在ra.xml描述符中定義，但我無法將消息驅動Bean（MDB）連接到它。 RA的eis一邊按預期工作，我可以用telnet連接/發送消息給它。當我嘗試用wildfly Maven插件部署MDB，對MDB找不到TcpMessageListener和我java.lang.NoClassDefFoundError：無法將MDB鏈接到Wildfly 10.x上的入站資源適配器 - 部署失敗

在EJB的Maven子模塊的依賴性是在provided範圍。我跟着部署了RA redhat guide。我還將ejb子模塊中的資源適配器的Maven依賴關係從提供的代碼切換到了編譯。在這種情況下，我得到了以下錯誤
[ERROR] Caused by: java.lang.IllegalStateException: WFLYEJB0383: No message listener of type de.bitc.jca.inflow.TcpMessageListener found in resource adapter tcp-eis.rar"},

這裏是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
}
}
這裏是TcpListenerInterface
package de.bitc.jca.inflow;
/**
* TcpMessageListener
*
* @version $Revision: $
*/
public interface TcpMessageListener {
/**
* Receive message
*
* @param msg
* String.
*/
public void onMessage(String msg);
}
這裏是在jboss_cli

我的問題是，部署中是否存在MDB找到資源適配器的缺少步驟。我認爲這是通過@ResourceAdapter註釋完成的？我需要定義一個隊列還是什麼？有關入站資源適配器的資源非常少見，大多數示例都是出站資源適配器。提前致謝。
上面鏈接的入站ra示例託管在github上。我描述了在github項目的README.md中構建和運行它的所有步驟。我想爲其他具有相同問題的人找到文檔來舉辦這些示例。
