springboot中使用网关和微服务进行端口映射

Question

也许我不太了解使用 docker-compose 和非常简单的网关进行端口映射。除了网关之外，所有项目都运行良好。

我的 application.yml 如下：

spring:
  application:
    name: api-gateway

  cloud:
    gateway:
      routes:
        - id: usermanager
          uri: http://usermanager:1111
          predicates:
            - Path=/user/
        - id: catalogmanager
          uri: http://catalogmanager:2222
          predicates:
            - Path=/catalog/
        - id: paymanager
          uri: http://paymanager:3333
          predicates:
            - Path=/payment/**

而 docker-compose 是：

version: '3.4'

x-common-variables: &common-variables
  DATASOURCE_USER: ${DB_USER}
  DATASOURCE_PASSWORD: ${DB_PASSWORD}
  DATASOURCE_PORT: ${DB_PORT}

调用时返回的错误，例如：http://localhost:8080/user/getAllUser 如下：

I'm trying to create a simple gateway that the request made on localhost/8080 route through the different microservices. Can someone explain me if something is wrong configured?
