Question

我有一个支持Kafka的Spring Boot应用程序。最近，我试图使其也支持RabbitMQ。我使用@Profile注释设置了代码，以便只有当我选择spring.profiles.active为rabbit-mq时，RabbitMQ的所有新代码才应处于活动状态。同样，特定于Kafka的代码由kafka的配置文件值标记出来

我惊讶地发现，即使使用上述设置，当我将配置文件设置为kafka时，仍通过 JMX暴露机制包含并激活了某些RabbitMQ。具体来说，首先构造了一个rabbitConnectionFactory bean，然后它尝试与localhost:5672处的RabbitMQ代理进行健康检查，但失败了。

在日志文件中，我看到了以下消息：

我有两个问题：

如何避免包含RabbitMQ代码？为什么我使用@Profile进行的设置无法正常工作？
如何配置rabbitConnectionFactory？目前，它正在尝试与localhost:5672进行通话。我通常知道如何设置Spring模板以将application-xxx.properties用于spring.rabbitmq.{host,port}，但是在这种情况下，由于代码是自动包含的，所以我不知道如何配置{{1 }}

常规配置

rabbitConnectionFactory

更新

尝试1：排除spring.rabbitmq.host=someRabbitBroker spring.rabbitmq.port=5672

谢谢你的建议。我尝试了他的方法，并按如下方式更改了RabbitAutoConfiguration。这里的想法是在未定义@SpringBootApplication时（当RabbitAutoConfiguration的配置文件未激活时）排除spring.rabbitmq.host：

rabbit-mq

我不确定这段代码是否是正确的方法，但是没有用。当我的应用启动时，我仍然在消息中看到这些：

@SpringBootApplication
public class Application {

    @ConditionalOnProperty(value="spring.rabbitmq.host")
    @Bean 
    RabbitAutoConfiguration rabbitAutoConfiguration(){
        return new RabbitAutoConfiguration();
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

只要可以停止进行运行状况检查（或至少将其配置为使用我指定的主机和端口），我就可以构造bean。有办法吗？

您要么需要从类路径中排除spring-rabbit jar，要么通过从RabbitAutoConfiguration中排除@SpringBootApplication来禁用Rabbitmq自动配置。

更新：禁用健康检查

请参见boot properties documentation。将management.health.rabbit.enabled设置为false
