不行,我们不能通过localhost直接调用,这里的术语是“容器调用容器”,所以,我们应该通过容器名称一起调用。

  1. 像这样更改 docker-compose:
order-service:
  build: docker/order-service
  container_name: order-service
  ports:
    - 8082:8080
  1. 然后,在客户端服务中,我们只需定义主机,如下所示:

私有字符串主机名 = “http://order-service:8080/order-service/welcome”;

你可以看到,当我们通过浏览器(真实客户端)调用订单服务时,我们通过扩展端口(8082)来调用,但是如果容器调用容器,我们应该通过它的名称和端口(8080)来调用).

s container

检查哪个地址打开了哪些端口。

使用发现服务器/尤里卡服务器,设置你的

netstat -tulpen

您选择的名称也可以是容器的container_name
