Question

我正在关注一些教程here，以了解如何在已部署的Jboss EAP 6.4服务器上使用camel路由。我当前应用程序的目标非常简单，因为我想从ActiveMQ主题中读取并将其注销。下面的代码总结了我的行动：

package com.mycompany;

import javax.ejb.Startup;
import javax.enterprise.context.ApplicationScoped;
import javax.jms.ConnectionFactory;

import org.apache.activemq.ActiveMQConnectionFactory;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.cdi.ContextName;
import org.apache.camel.component.jms.JmsComponent;

@ApplicationScoped
@Startup
@ContextName("com.mycompany")
public class CamelRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        System.out.println("### we are in the main");

        final ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616");
        getContext().addComponent("jms", JmsComponent.jmsComponentAutoAcknowledge(factory));

        System.out.println("#### route being called");
        from("jms:topic:activemq/topic/myTopic").log("###### we are in here with this message ${body}");

    }
}

我还有一个Launcher类来测试我的路线：

package com.mycompany;

import org.apache.camel.main.Main;

public class Launcher {

    public static void main(final String... args) throws Exception {
        final Main main = new Main();
        main.addRouteBuilder(new CamelRoute());
        main.run(args);
    }
}

如果我通过以下maven命令启动路由，我可以收到发送到activemq主题的所有消息。所以我知道，如果我手动启动路线，我至少可以检索数据。

mvn clean install exec:java -Dexec.mainClass=com.mycompany.Launcher

但是，一旦我将我的应用程序部署到服务器（作为jar，启用），同样不能说。我的system.out语句都没有在日志中显而易见。我几乎感到好像缺少额外的配置来“启动”应用程序。

注意：我在CamelRoute类中添加了用于启动的EJB注释，但这并没有解决问题。我错过了一些明显的东西吗？

我部署jar后，从jboss eap 6.4 log输出：

日志输出中有一个指针，指出了此问题的可能原因：

JBAS016012: Deployment deployment "camel-java-1.0.0-SNAPSHOT.jar" contains CDI annotations but beans.xml was not found.

您需要确保在JAR中添加META-INF/beans.xml。直到CDI 1.1才添加隐式bean档案。 EAP 6.x / JavaEE 6使用CDI 1.0。如果部署中不存在beans.xml，则Camel CDI应用程序将永远不会被提升并启动。

路由未执行：camel / fuse / activemq
