[英]finishConnect(..) failed: Connection refused: localhost/127.0.0.1 , error: Webflux, Webclient, Spring boot, java

我在 localhost 中使用 webclient 时遇到此错误,你们能帮帮我吗??

不行,我们不能直接通过localhost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,我们只需像下面这样定义主机:

private String hostname = "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)调用,但是如果容器调用容器,我们应该通过它s container名称和它的端口(8080)来调用。

连接被拒绝意味着没有服务器监听地址:端口。 您可以使用netstat -tulpen检查在哪个地址上打开了哪些端口。
