Question

我本来要发布这个问题，但我想我已经找到了答案。我希望有人能够提供进一步公开知识的理由。

我正在将RabbitMQ集成到我的Spring Boot应用程序中。

启动Spring Boot应用程序后，我会不断获取此堆栈跟踪

org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection refused (Connection refused)

我将RabbitMQ简化为空，仅在pom.xml中具有依赖关系，而在application.properties中具有以下依赖关系

spring.rabbitmq.host=localhost
spring.rabbitmq.port=15672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

我确认Rabbit MQ已启动并正在运行，甚至可以进入GUI

我的解决方案是将spring.rabbitmq.port更改为5672（删除1）

任何人都可以提供技术答案吗？是因为RabbitMQ侦听该端口5672并仅在15672上提供了前端

Answer 1

RabbitMq使用高级消息队列协议（AMQP）。

在rabbitmq.conf中，提供的tcp端口从Java应用程序中获取RabbitMq的端口。

listeners.tcp.default = 5672

RabbitMQ管理控制台或Web管理员使用15672（默认）端口。

Rabbit MQ无法从Spring Boot Run启动（连接被拒绝）
