无法连接到Cloudfoundry Micro Instance中的RabbitMQ

Question

我有一个应用程序我已经在cloudfoundry.com上运行了一段时间，并且在部署到api.cloudfoundry.com时一切正常。我最近建立了一个CF Micro实例，在云环境中进行本地测试，当我的应用程序部署到微实例时，它无法连接到我的兔子服务。我得到以下异常：

    org.springframework.integration.amqp.outbound.AmqpOutboundEndpoint.handleRequestMessage(AmqpOutboundEndpoint.java:192)

我不确定该看什么（我确定微观实例中有些东西我可以看，但不确定是什么），所以我想我会问这里。

我已验证该服务存在：

vmc services
Getting services... OK

name                    service    version
xxx-mongo    mongodb    2.0    
xxx-mysql    mysql      5.1    
xxx-rabbit   rabbitmq   2.4    

我已经验证该服务已绑定到我的应用程序：

vmc app myapp
myapp: running
  platform: spring on java
  usage: 512M × 1 instance
  urls: mydomain.cloudfoundry.me
  services: xxx-mysql, xxx-rabbit, xxx-mongo

我甚至尝试重新绑定它，但它说它受到约束：

vmc bind-service xxx-rabbit myapp
Binding xxx-rabbit to myapp... SKIPPED
App myapp already binds xxx-rabbit.

我的应用是一个Spring应用程序。兔子服务的配置设置如下：

<?xml version="1.0" encoding="UTF-8"?>

    <jdbc:initialize-database data-source="jdbcDataSource">
        <jdbc:script location="classpath:oauthTokenStoreSchema.sql"/>
    </jdbc:initialize-database>
</beans>

这个配置依赖于Spring自动重新配置，据我所知，它正常工作。它不会作为启动抱怨，只有当我真的尝试将消息发送到队列时才会这样：

org.springframework.integration.Message<Message> msg = MessageBuilder.withPayload(m).build();
messagesChannel.send(msg);

最后，我登录微实例查看兔子是否真正在运行，它似乎是：

同样，当我部署到api.cloudfoundry.com时，应用程序可以连接到rabbitmq就好了。如果有帮助的话，我正在运行微型v119。

你能提供的任何帮助都会很棒！感谢。

编辑： 根据Hitesh的建议，我尝试使用云配置文件，但这不起作用。我也试过这个：

<beans profile="default">
        <rabbit:connection-factory
            id="rabbitConnectionFactory"
            host="localhost"
            password="testpwd"
            port="1238"
            username="testuser"
            virtual-host="virthost" />
        <rabbit:template id="rabbitTemplate" connection-factory="rabbitConnectionFactory"/>
    </beans>

    <beans profile="cloud">
        <cloud:rabbit-connection-factory id="rabbitConnectionFactory" />
        <rabbit:template id="rabbitTemplate" connection-factory="rabbitConnectionFactory"/>
    </beans>

有趣的是，我试过这个（复制出来的文档）：

<rabbit:connection-factory
    id="rabbitConnectionFactory"
    host="localhost"
    password="testpwd"
    port="1238"
    username="testuser"
    virtual-host="virthost" />
<rabbit:template id="rabbitTemplate" connection-factory="rabbitConnectionFactory"/>

现在我的发送应用程序正常运行！但我的接收应用仍然无法正常工作。它收到了这个错误：

我已经尝试了上面的所有配置，但都没有工作。

Answer 1

我建议尝试使用rabbitmq的示例弹簧应用程序，它住在这里： https://github.com/rabbitmq/rabbitmq-cloudfoundry-samples/tree/master/spring。还有一个逐步的文档来帮助您完成它。您可以将配置与您的应用进行比较，如果有效，则表示配置中可能缺少某些内容。 如果这没有用，那么你可以在这里发布一个问题＆＃34; http://support.cloudfoundry.com＆＃34; 让我们访问您的应用程序，以便我们自己尝试部署它。

Answer 2

我建议你尝试更换这些行：

<!-- Set up the AmqpTemplate/RabbitTemplate: -->
<rabbit:connection-factory id="rabbitConnectionFactory"/>

with：

<!-- Obtain a connection to the RabbitMQ via cloudfoundry-runtime: -->
<cloud:rabbit-connection-factory id="connectionFactory"/>

后一种情况是使用云命名空间来读取兔子 -
