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

Question

我一直在尝试开发一个同时使用activeMQ和rabbitMQ的项目。我在pom.xml中添加的依赖项如下所示：

    <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，我还同时运行了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，如下所示：

如果有人帮我解决这个错误，我将不胜感激。

Answer 1

解决方案只需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，您只需更改其中一个端口的配置即可。

对于rabbitMQ，您可以参阅这里解释的说明，就像@Kenney所说的，它就像设置环境变量一样简单。

注意：在设置变量期间，不要忘记重新安装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完成此操作：

1. cd放入RabbitMQ服务器安装目录下的sbin文件夹中，然后运行RabbitMQ-service.bat remove
2. 设置RABBITMQ_NODE_PORT=xxxx
3. rabbitmq-service.bat安装

此外，如果它不起作用，您可以简单地为amqp更改ActiveMQ的默认端口。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。我希望这对你有用。

协议AMQP在端口5672上工作，这两个消息代理都支持该协议。只需将其中一个移动到另一台机器即可。
