rabbitmq Attempting to connect to: [localhost:5672] SocketExceptio:Socket Closed

今天使用spring cloud stream for rabbitmq启动项目报错:

以为端口有问题。检查了下Docker的端口映射

PS C:\Users\wangn> docker ps

没问题。‘

去谷歌了一遍也没有解决。

直到我将application.properties文件中的

spring.rabbitmq.host=localhost
复制代码

换成

spring.rabbitmq.host=10.0.75.2
复制代码

启动就不报错了。

其中10.0.75.2是docker容器的IP地址
