Question

我是Azure Service Bus和apache qpid的新手。我正在尝试使用https://qpid.apache.org/releases/qpid-jms-amqp-0-x-6.3.4/jms-amqp-0-8-book/JMS-Client-0-8-Appendix-Tomcat-JNDI-Integration.html中提到的在Tomcat context.xml中使用AMPConnectionFactory连接Azure服务总线，并配置JMS对等缓存复制

pom.xml

 <dependency>
            <groupId>org.apache.qpid</groupId>
            <artifactId>qpid-jms-client</artifactId>
            <version>0.47.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.qpid</groupId>
            <artifactId>qpid-client</artifactId>
            <version>6.3.4</version>
        </dependency>

Tomcat context.xml

    <Resource name="testConnectionFactory" auth="Container"
            type="org.apache.qpid.client.AMQConnectionFactory"
            factory="org.apache.qpid.jndi.ObjectFactory"
            connectionURL="amqp://rootmanagesharedaccesskey:*********=/? 
           brokerlist='servicebusurl:5672'"/>
   <Resource name="myqueue" auth="Container"
            type="org.apache.qpid.client.AMQQueue"
            factory="org.apache.qpid.jndi.ObjectFactory"
             address="BURL:direct://amq.direct//myqueue?durable='true'"/>`
    <Resource name="mytopic" auth="Container"
            type="org.apache.qpid.client.AMQTopic"
            factory="org.apache.qpid.client.AMQConnectionFactory"
            address="BURL:topic://amq.topic//mytopic?routingkey='mytopic'"/>

ehcache.xml

<cacheManagerPeerProviderFactory
    class="className extending JMSCacheManagerPeerProviderFactory"
    properties="initialContextFactoryName=org.apache.qpid.jms.jndi.JmsInitialContextFactory,
        replicationTopicConnectionFactoryBindingName=java:comp/env/testConnectionFactory,
        replicationTopicBindingName=java:comp/env/mytopic,
        getQueueConnectionFactoryBindingName=java:comp/env/testConnectionFactory,
        getQueueBindingName=java:comp/env/myqueue"
    propertySeparator="," />

扩展JMSCacheManagerPeerProviderFactory的

className包含以下代码片段。我无法按照政策发布完整的课程

TopicConnectionFactory topicConnectionFactory;
topicConnectionFactory = (TopicConnectionFactory) context.lookup(replicationTopicConnectionFactoryBindingName);
replicationTopicConnection = topicConnectionFactory.createTopicConnection("username","password");

上面的代码抛出异常。我是否缺少任何jar版本或不正确的版本？当我调试时，与azure服务名称空间的套接字连接已启用，但在等待以下异常后被关闭。请指教

您的第一个问题是您的项目中包含两个不同的AMQP JMS客户端：

这是一个基于AMQP 1.0的AMQP客户端，由于AMQP 1.0是ISO标准AMQP协议，因此正在积极开发中。

<dependency>
    <groupId>org.apache.qpid</groupId>
    <artifactId>qpid-jms-client</artifactId>
    <version>0.47.0</version>
</dependency>

这是旧版AMQP 0.x JMS客户端，尚未积极开发，由于出现严重问题，它偶尔会收到一些错误修复版本。

<dependency>
    <groupId>org.apache.qpid</groupId>
    <artifactId>qpid-client</artifactId>
    <version>6.3.4</version>
</dependency>

因此，您需要选择这两者之一，并且由于您尝试使用Azure，因此应该选择第一个，因为Azure是基于AMQP 1.0的邮件系统。因此，第二个问题是您已将tomcat配置为使用旧版客户端，而Azure不支持它可以说的协议，因此会出现错误。

使用apache qpid-client连接到Azure服务总线时出现问题
