Question

I have an Azure Service bus topic set up called "state-changed" and it has a subscription called "reverb". I'm trying to set up a method with @JmsListener to subscribe to the topic but am getting an error:

2017-03-22 18:34:41.049  WARN 23356 --- [enerContainer-6] o.s.j.l.DefaultMessageListenerContainer  : Setup of JMS message listener invoker failed for destination 'state-changed' - trying to recover.

I have been using this blog post to try and get everything up and running: http://ramblingstechnical.blogspot.co.uk/p/using-azure-service-bus-with-spring-jms.html

I can add messages to the topic with JmsTemplate and read messages from it using the plain old Java JMS libraries outlined in the Azure docs: https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-java-how-to-use-jms-api-amqp so I know my topic does work and is accessable, it just seems to be when I configure it with Spring that I'm doing something wrong.

My configuration looks like:

@Configuration
public class JmsConfiguration
{

    @Bean
    public JmsListenerContainerFactory topicJmsListenerContainerFactory() throws NamingException
    {
        DefaultJmsListenerContainerFactory returnValue = new DefaultJmsListenerContainerFactory();

        Context context = context();
        ConnectionFactory cf = connectionFactory(context);

        returnValue.setConnectionFactory(cf);
        returnValue.setSubscriptionDurable(Boolean.TRUE);
        return returnValue;
    }

    private Context context() throws NamingException
    {
        Hashtable<String, String> env = new Hashtable<String, String>();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.qpid.amqp_1_0.jms.jndi.PropertiesFileInitialContextFactory");
        env.put(Context.PROVIDER_URL, "src/main/resources/servicebus.properties");
        Context context = new InitialContext(env);
        return context;
    }



    /**
     * @param context
     * @return
     * @throws NamingException
     */
    private ConnectionFactory connectionFactory(Context context) throws NamingException
    {
        ConnectionFactory cf = (ConnectionFactory) context.lookup("SBCF");
        return cf;
    }

}

servicebus.properties (with username and password etc redacted):

# servicebus.properties - sample JNDI configuration

# Register a ConnectionFactory in JNDI using the form:
# connectionfactory.[jndi_name] = [ConnectionURL]
connectionfactory.SBCF=amqps://[USER]:[PASSWORD]@[MYSERVICEBUS]

# Register some queues in JNDI using the form
# queue.[jndi_name] = [physical_name]
# topic.[jndi_name] = [physical_name]
queue.workflow = workflow
topic.state-changed = stage-changed

And finally my listener class:

@Component
public class TestListener
{
    Logger logger = LoggerFactory.getLogger(LoggingWorkflowEventHandler.class);

    @JmsListener(destination = "state-changed", containerFactory = "topicJmsListenerContainerFactory", subscription = "reverb")
    public void onMessage(String message)
    {
        logger.info("Received message from topic: {}", message);
    }
}

If anyone has ever managed to get this working I'd be grateful for some pointers.

Answer 1

您的错误消息表明找不到您的目的地名称（未找到消息实体）。请注意，您需要以特定方式告知Azure您的订阅名称：

<TopicName>/Subscriptions/<SubscriptionName>

在你的情况下：

state-changed/Subscriptions/reverb

希望有所帮助

如果您使用 Spring Boot，则可以使用准备好的 Azure ServiceBus JMS Spring Boot Starter，它可以开箱即用。

<dependency>
    <groupId>com.microsoft.azure</groupId>
    <artifactId>azure-servicebus-jms-spring-boot-starter</artifactId>
    <version>2.3.5</version>
</dependency>

Answer 3

创建或更改Trustrore：

由于我们要建立与服务总线的安全amqps连接，我们需要将所有必需的SSL证书存储在信任库中。由于似乎没有现有的证书包含所需的证书我 - 为了透明度 - 创建了一个像这样的新证书：

访问https://<URL-Of-Your-Servicebus>获取所需的证书，例如浏览器中的https://XXXXX.servicebus.cloudapi.de。然后点击＆＃34;锁定＆＃34;在URL中（或您的浏览器显示的任何安全连接）并从那里打开证书。

保存当前证书：

[ Certificate provide ]

当要求输出格式时，选择＆＃34; DER二进制＆＃34;并将其保存为＆＃34; .cer＆＃34;文件，例如＆＃34; 1.cer＆＃34;

您很可能会看到您的证书基于证书链，这意味着它取决于其他证书。对于每个点击＆＃34;显示证书＆＃34;：

[ Certificate provide ]

以与之前相同的方式保存那个。重复，直到到达根证书。在此示例中，您将得到三个* .cer文件。如需进一步参考，我将称之为1.cer，2.cer和3.cer

您现在应该为这些证书创建一个新的Truststore文件

/opt/webMethods9/jvm/jvm/bin/keytool -import -file
/opt/webMethods9/IntegrationServer/instances/default/packages/DEV_fse/resources/1.cer -keystore azureTruststore.jks -alias "D-TRUST Root Class 3 CA 2 2009"

/opt/webMethods9/jvm/jvm/bin/keytool -import -file 
/opt/webMethods9/IntegrationServer/instances/default/packages/DEV_fse/resources/2.cer -keystore azureTruststore.jks -alias "D-TRUST SSL Class 3 CA 1 2009"

/opt/webMethods9/jvm/jvm/bin/keytool -import -file 
/opt/webMethods9/IntegrationServer/instances/default/packages/DEV_fse/resources/3.cer -keystore azureTruststore.jks -alias "servicebus.cloudapi.de"

首次要求您为此新创建的信任库设置密码。现在将信任库移动到/opt/webMethods9/IntegrationServer/config/certs/trusted（供以后参考）。您可以将其作为信任库添加到IS（通过使用admin-UI＆＃34; Security＆gt; Keystore＆＃34;以及＆＃34;创建Truststore Alias＆＃34;），但是没有技术需要这样做，就像在我们的例子中，IS没有使用信任库 - 它仅由QPID使用。

为JNDI创建属性文件您需要创建一个servicebus.properties文件作为伪JNDI服务器的数据源。你可以在技术上将文件放在任何你想要的地方，但我建议把它放在＆＃34;资源＆＃34; ＆＃34; XXXXXXConnection＆＃34;的文件夹包。这应该是该文件的内容：

# servicebus.properties - sample JNDI configuration
# Register a ConnectionFactory in JNDI using the form:
# connectionfactory.[jndi_name] = [ConnectionURL]
connectionfactory.SBCF = amqps://XXXXXX.servicebus.cloudapi.de?jms.username=xxxxx&jms.password=xxxxxxx&amqp.idleTimeout=120000&jms.receiveLocalOnly=true&transport.trustStoreLocation=/opt/webMethods9/IntegrationServer/config/certs/trusted/azureTruststore.jks
# Register some queues in JNDI using the form 
# queue.[jndi_name] = [physical_name] 
# topic.[jndi_name] = [physical_name]
queue.QUEUE = myqueue

一些解释：

SBCF将是连接工厂的JNDI-Lookup名称。稍后需要在JMS-Connection
xxxxxx.servicebus.cloudapi.de是服务总线的网址
jms.username将由友好的Azure管理员提供
jms.password将由您友好的Azure管理员提供。但请注意，您需要对来自管理员的内容进行URL编码，然后才能在此URL中使用它。例如，可以通过在Designer中手动调用IS服务pub.string:URLEncode来完成。
amqp.idleTimeout需要设置为120000（或更高），因为否则您无法连接到SB
jms.receiveLocalOnly需要设置为true，因为否则您无法连接到SB
transport.trustStoreLocation需要指向包含创建与SB的安全（AMQPS）连接所需的所有SSL证书的信任库
queue.QUEUE：QUEUE是稍后将在JMS-Client中用于发送消息的JNDI-Lookup名称，或者在JMS-Trigger中用于接收它们。你应该设置一个更有意义的东西。此值（＆＃34; myqueue＆＃34;在示例中）是SB上队列的名称，必须由Azure管理员提供。

[ JNDI context factory class ]

唯一的两个重要值是：

＆＃34;初始上下文工厂＆＃34;：org.apache.qpid.jms.jndi.JmsInitialContextFactory
＆＃34;提供商URL＆＃34;：必须指向您创建的servicebus.properties，例如file:/opt/webMethods9/IntegrationServer/instances/default/packages/XXXXXXConnection/resources/servicebus.properties
