spring-boot - 带有两个 Spring Boot 应用程序的 Docker Compose 得到“消息”：“对 \”http://127.0.0.1:8010/...的 GET 请求出现 I/O 错误：连接被拒绝”

问题描述

我有两个小型 Spring Boot 应用程序，它们公开了一个休息 API：

应用程序一

获取请求

 - http://localhost:8010/api/stock/AAPL

回复：

{
    "name": "AAPL",
    "value": 219.9
}

应用程序二

获取请求

 - http://localhost:8080/api/trade/APPL/buy/10

{
    "id": 1,
    "stock": {
        "name": "APPL",
        "value": 219.9
    },
    "quantity": 10,
    "total": 2199.0
}

当我在没有 Docker 的本地主机上运行这两个应用程序时，我从两个 API 中得到了正确的响应。

当我使用 Docker Compose 运行应用程序时，第一个 API 应用程序一响应 OK，但应用程序二返回错误：

"message": "I/O error on GET request for \"http://127.0.0.1:8010/api/stock/APPL\": Connection refused (Connection refused); nested exception is java.net.ConnectException: Connection refused (Connection refused)",
"path": "/api/trade/APPL/buy/10"

这是我的 docker-compose.yml 配置文件：

version: "3.7"
services:
  app-one:
    image: ibercode/app-one
    ports:
    - "8010:8010"
    expose:
      - "8010"
  app-two:
    build: .
    ports:
      - "8080:8080"
    depends_on:
      - app-one      
    environment:
      - APP_ONE_URI=http://127.0.0.1:8010/api/stock/

这是我运行命令后的输出docker-compose up
