Question

我一直在尝试开发一个同时使用activeMQ和rabbitMQ的项目。我在下面列出的pom.xml中添加的依赖项：

    <dependency>
        <groupId>org.springframework.amqp</groupId>
        <artifactId>spring-rabbit</artifactId>
        <version>1.4.6.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jms</artifactId>
        <version>4.2.3.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-broker</artifactId>
        <version>5.13.0</version>
    </dependency>

此外，我同时运行apache-activemq-5.13.0和rabbitmq-server-3.5.6。但不幸的是，我遇到了一个与AMQP有关的错误，并在下面说明：

如果有人帮我解决这个错误，我将不胜感激。

Answer 1

解决方案只是更改其中一个消息代理端口号。由于它们都在同一个端口（5672）上工作，因此您只需更改其中一个端口的配置即可。

对于rabbitMQ，您可以使用here解释的说明，就像@Kenney说它就像设置环境变量一样简单。

注意：请勿忘记在设置变量时重新安装RabbitMQ服务。

在Windows中，您可以通过在命令提示符下运行以下命令来执行此操作：

cd进入RabbitMQ服务器安装目录下的sbin文件夹并运行rabbitmq-service.bat remove
设置RABBITMQ_NODE_PORT = xxxx
rabbitmq-service.bat install

此外，如果它不起作用，您只需更改amqp的ActiveMQ的默认端口即可。为此，您应该在ActiveMQ服务器安装目录中的 conf 文件夹中查找文件名activemq.xml。我希望这适合你。

Answer 2

协议AMQP在端口5672上工作，消息代理都支持该协议。只需将其中一个移到另一台机器上即可。

同时在同一台机器上运行ActiveMQ和RabbitMQ时，AMQP协议版本错误
