如何使用 ActiveMQ 设置 Spring 云总线？

Question

我想在我的项目中使用 Spring Cloud Bus 来动态更新配置。我们的环境中已经有了 Apache ActiveMQ。有没有可能使用 ActiveMQ 而不是 RabbitMQ 作为代理？它们都是一种AMQP服务器。

我在 pom.xml 中设置依赖是这样的：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bus-amqp</artifactId>
</dependency>

它看起来像一个标准的 AMQP starter，不限于 RabbitMQ。但是config server启动的时候出现如下错误日志提示：

Is there any possible to use ActiveMQ instead RabbitMQ as the broker?

据我所知ActiveMQ只提供AMQP 1.0，rabbit client是0.9.1，所以答案是"no"。如果您为 AMQP 1.0 或 JMS 或 ActiveMQ 中的其他协议之一提供了 spring-cloud-stream 绑定器，您可能能够以这种方式使用它（在 Spring Cloud 的 Brixton 版本中） .它们不是开箱即用的，所以你必须自己写。
