Artemis qpid消费者无法与经纪人建立联系

分类：编程问答

如何解决Artemis qpid消费者无法与经纪人建立联系

下面是Qpid客户端的配置，使用Camel上下文连接Artemis经纪人。

上下文文件已按预期启动，但是在这种情况下，qpid客户端无法连接到Apache Artemis 2.14.0代理。

qpid客户端无法连接代理服务器，并且存在线程阻止。我不确定客户端实际发生了什么。

但是我们注意到，对于另一项服务，我们使用单个spring camel上下文文件，其中所有队列和引用均按预期工作。

生产者使用camelContextAware实现使用生产者模板来推送消息数据。

队列中的生产者和消费者是否有可能在这里发生冲突？

我所看到的只是用户端的一些线程块。

common-context.xml 

...
 <bean id="jmsConnectionFactory" class="org.apache.qpid.jms.JmsConnectionFactory">
            <property name="remoteURI" value="failover:(amqp://host1:5672,amqp://host2:5672)"/>
    </bean>
 <bean id="pooledConnectionFactory" class="org.messaginghub.pooled.jms.JmsPoolConnectionFactory"
                    init-method="start" destroy-method="stop" >
        <property name="maxConnections" value="3" />
        <property name="connectionFactory" ref="jmsConnectionFactory" />
 </bean>
 <bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
        <property name="connectionFactory" ref="pooledConnectionFactory" />
        <property name="concurrentConsumers" value="3" />
 </bean>
 <bean id="env-queue" class="org.apache.camel.component.amqp.AMQPComponent">
        <property name="configuration" ref="jmsConfig" />
 </bean>
...

service-context.xml 注意：在这个单独的xml文件中，即使使用骆驼2.20.0版本，所有上下文都得到了两个骆驼上下文

...
< import resource="classpath:/common-context.xml"/>
...
<route id="messageProcessor" shutdownRoute="Default" shutdownRunningTask="CompleteAllTasks">
    <from uri="env-queue:queue:order-demo-queue" id="OrderInfo"/>
    <camel:setProperty propertyName="orderType">
       <camel:jsonpath trim="true">$.orderType</camel:jsonpath>
    </camel:setProperty>
...

已更新：

当我将remoteUri更改为简单的amqp://localhost:5672时，我在netty-resolver上看到一个异常

 java.lang.NoClassDefFoundError: "io/netty/resolver/AddressResolverGroup"

包括netty-resolver 4.1.51 jar之后，现在我看到以下异常。

解决方法

Qpid客户端正尝试使用配置的故障转移机制进行连接。客户端似乎无法连接，这可能是由于没有代理服务正在运行或根本无法访问，或者是由于配置错误（例如，与非SSL接受者的SSL连接）或相反。如果为了符合JMS规范要求而没有连接，则客户端将阻止连接启动。您需要更深入地了解为什么无法联系到您的经纪人。

,

在使用amqp的故障转移配置时，客户端在主机之间交替而不打印任何异常日志。

将ConnectionFactory，remoteUrl更新为使用单个主机（amqp：// localhost：5672），并注意到该异常是在netty.io.resolver上。

我包括了以下依赖项，现在连接已按预期建立。

    <dependency>
      <groupId>io.netty</groupId>
      <artifactId>netty-resolver</artifactId>
      <version>4.1.51.Final</version>
