Question

我尝试使用ActiveMQComponent通过camel cdi初始化org.apache.activemq.pool.PooledConnectionFactor。使用ActiveMQConnectionFactory，这可以正常工作。

我还添加了一些日志，并注意到当PooledConnectionFactory，CamelContext关闭时。在构建和部署时我用JMSConfigurations等尝试了许多不同的方法，但仍然没有运气。

这可能是什么原因？

错误日志。

我可以继续使用ActiveMQConnectionFactory并以不同方式处理maximumConnections / timeouts。但我喜欢最好的。

ActiveMQComponentProducer.java

@ApplicationScoped
public class ActiveMQComponentProducer {

    @Produces
    @Named("activemqx")
    public ActiveMQComponent createActiveMQComponent() {

        System.out.println("Creating ActiveMQ Component");

        ActiveMQComponent activeMQComponent = ActiveMQComponent.activeMQComponent();
        String connectionString = "tcp://localhost:61616";

        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(connectionString);
        System.out.println("createActiveMQComponent().connectionFactory : " + connectionFactory);

        PooledConnectionFactory pooledConnectionFactory = null;
        System.out.println("createActiveMQComponent(). : mark-1");

        try {
            pooledConnectionFactory = new PooledConnectionFactory(connectionFactory);
        } catch (Exception e) {
            System.out.println("createActiveMQComponent(). : "+e);
        }
        System.out.println("createActiveMQComponent(). : mark-2");

        activeMQComponent.setConnectionFactory(pooledConnectionFactory);
        return activeMQComponent;
    }

}

您可能遇到了类加载问题。

在WildFly-Camel 4.9.0版本中，PooledConnectionFactory不会自动导出到部署类路径上。此问题在将来的版本中已得到修复，并且已被此问题跟踪：

https://github.com/wildfly-extras/wildfly-camel/issues/2199

作为一种变通方法，您可以通过org.apache.activemq描述符为部署添加jboss-deployment-structure.xml的模块依赖关系。将其放在META-INF内进行JAR部署，或WEB-INF进行WAR部署。

<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="org.apache.activemq" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>

初始化PooledConnectionFactory时，CamelContext正在关闭
