Question

我有一个Spring Boot应用程序，我将其部署到Cloud Foundry实例（BlueMix）。我已将CloudAMQP实例绑定到应用程序，并希望将其用于发送我的STOMP消息。我无法正确配置我的StompBrokerRelayRegistration类以成功连接CloudAMP中的RabbitMQ实例。我打电话了

config.enableStompBrokerRelay("/topic", "/queue");

但是这次尝试连接到localhost。我以为它可能会尝试使用我的org.springframework.amqp.rabbit.connection.ConnectionFactory bean，但我猜不是。

然后我尝试使用VCAP_SERVICES中的信息调用setRelayHost，setRelayPort，setSystemLogin，setSystemPasscode和setVirtualHost。执行此操作后，Spring似乎尝试连接到RabbitMQ实例，但基于日志，连接立即关闭

通过对等方重置连接

。任何人都知道我可能做错了什么？

更新

显然我使用的是错误的端口。使用端口5672会导致立即关闭连接的行为。如果我使用端口61613，则似乎建立了连接。但是，一旦浏览器尝试建立websocket，就会抛出以下异常

任何人都知道这里出了什么问题？

Answer 1

弄清楚我错过了什么。除了调用setSystemLogin和setSystemPasscode之外，我还需要在StompBrokerRelayRegistration上调用setClientLogin和setClientPasscode。执行此操作后，我从浏览器到Cloud Foundry上的应用程序的WebSocket连接正常工作，Spring可以使用CloudAMQP中的RabbitMQ实例发送STOMP消息。

如何使用CloudAMQP配置Spring Websockets
