java - 无法将 MDB 链接到 Wildfly 10.x 上的入站资源适配器 - 部署失败

Question

我将一个简单的 TCP 入站资源适配器 (RA) 编程为 example project在 github 上，并使用独立完整配置成功将其部署到 wildfly 10.x。消息监听器 TcpMessageListener 接口(interface)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 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 并且出现 java.lang.NoClassDefFoundError:

WARN  [org.jboss.modules] (MSC service thread 1-7) Failed to define class de.bitc.ejb.InboundEventHandler in Module "deployment.ra-ear.ear.ra-user-ejb-0.0.1-SNAPSHOT.jar:main" from Service Module Loader: java.lang.NoClassDefFoundError: Failed to link de/bitc/ejb/InboundEventHandler (Module "deployment.ra-ear.ear.ra-user-ejb-0.0.1-SNAPSHOT.jar:main" from Service Module Loader): de/bitc/jca/inflow/TcpMessageListener

ejb maven 子模块中的依赖项位于 provided 范围内。我随后部署了 RA redhat guide 。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"},

  "WFLYCTL0180: Services with missing/unavailable dependencies" => undefined}}}

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);
}

这里是jboss_cli中资源适配器的设置

 /subsystem=resource-adapters/resource-adapter=tcp-eis.rar:read-resource(recursive=true)
{
    outcome => success,
    result => {
        archive => tcp-eis.rar,
        beanvalidationgroups => undefined,
        bootstrap-context => undefined,
        config-properties => undefined,
        module => undefined,
        statistics-enabled => false,
        transaction-support => XATransaction,
        wm-security => false,

        wm-security-mapping-users => undefined,
        admin-objects => undefined,
        connection-definitions => undefined
    }
}

我的问题是，部署中是否缺少 MDB 查找资源适配器的步骤。我认为这是通过 @ResourceAdapter 注释完成的？我需要定义一个队列什么的吗？有关入站资源适配器的资源非常少，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。我想为其他有同样问题的人托管这些示例来查找文档。

Answer 1

我解决了类加载 NoClassDefFoundError: Failed to link 错误，现在运行的示例回答了许多悬而未决的问题。我将所有详细信息放入我的 example 。入站资源适配器现在作为 Wildfly 10 (WF10) 上的 Ear 存档中的子部署运行。我使用 IronJacamar codegenerator 生成了入站资源适配器。我在示例中描述了如何构建和运行的所有步骤。

主要错误在于，我没有在ear存档中使用jboss-deployment-struct描述符以及ear存档中对资源适配器api的maven依赖。我在测试时把依赖项放进耳朵里就忘了。

<?xml version="1.0" encoding="UTF-8"?>  
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">  
    <ear-subdeployments-isolated>false</ear-subdeployments-isolated>  
    <sub-deployment name="ra-user-ejb.jar">  
        <dependencies>  
            <module name="deployment.ra-ear.ear.tcp-eis.rar"  export="true" />  
        </dependencies>  
    </sub-deployment>  
</jboss-deployment-structure>

以下是我最大的耳朵嵌入式入站 RA 答案，以解决一点文档泄漏问题:

• 不需要ra.xml描述符，RA类中的@Connector注释就足够了。
• WF10 中无需额外配置。没有队列、standallone-full.xml 修改或 jndi 内容。使用 wildfly-maven-plugin 进行简单部署即可工作。
• 当前工作的资源适配器未在 WF10 中显示为资源适配器。这让我很困惑，也让我的研究变得非常困难。
• 不需要jboss-ejb3.xml描述符。 @ResourceAdapter(value="ra-ear.ear#tcp-eis.rar") 就足够了。注意，这是 jboss 注释，而不是 ee7。所以你找不到任何资源，例如。 websphere 或 tomee。

我将在接下来的几天内将示例资源适配器扩展为完整的 ee7 应用程序，并希望此示例可以帮助其他人度过入站资源适配器文档 hell 。
