为了测试spring XD，我正在关注项目网页上的简短twitter流教程。 Tutorial运行单节点弹簧XD，并在流定义中使用文件作为接收器。我能够毫无问题地运行该教程。 XD的版本是1.0.0.M7。
后来，我决定使用rabbitmq，所以我在同一台机器上安装了rabbitmq（RabbitMQ 3.3.4），并将定义的接收器部分更改为兔子。
stream create --name twt2rabbit --definition "twitterstream | rabbit " --deploy false
在部署流之前，我更改了config / modules / modules.yml，如下所示。
#Shared RabbitMQ module properties
rabbit:
host: localhost
port: 5672
username: guest
password: guest
vhost: /
由于这些是默认参数，因此在部署流时没有任何问题。我检查了队列中的消息，它们是预期的。
问题在于，当我更改上面的参数以连接并发送到同一LAN上的另一台计算机上的rabbitmq时，我得到连接被拒绝。我检查了以下内容以缩小问题范围。
我收到的错误消息如下。
