Java 无法连接到mongo容器

java spring mongodb docker docker-compose

Java 无法连接到mongo容器,java,spring,mongodb,docker,docker-compose,Java,Spring,Mongodb,Docker,Docker Compose,我之前有一个问题（至少我认为）当我设法修复出现的错误时，或多或少变得毫无用处。。然而，我的新错误是，我似乎无法从docker映像中连接到mongodb docker-compose.yml： version: '3.1' services: company-repo-docker-app: image: company-repo-image build: context: ./ dockerfile: Dockerfile depends_on

我之前有一个问题（至少我认为）当我设法修复出现的错误时，或多或少变得毫无用处。。然而，我的新错误是，我似乎无法从docker映像中连接到mongodb

docker-compose.yml：

version: '3.1'
services:
  company-repo-docker-app:
    image: company-repo-image
    build:
        context: ./

application.properties：

spring.data.mongodb.database=myDb
spring.data.mongodb.host=172.28.0.2 
spring.data.mongodb.port=27017

实际误差：

您已经在

docker compose.yml

文件中显式创建了一个网络，并将数据库设置为使用该网络。Docker Compose还为您创建了一个默认网络，并且由于您的应用程序没有显式声明任何网络，因此只附加到默认网络。然后两个容器在不同的网络上，一个无法到达另一个

这里最简单的解决方案是删除所有手动网络配置：

version: '3.1'
services:
  company-repo-docker-app:
    image: company-repo-image
    build:
      context: ./
    depends_on:
      - mongo
    ports:
      - '8080:8080'
  mongo:
    image: mongo
    ports:
      - '27017:27017'

服务块的名称将是有效的DNS主机名，在您的配置中，您可以设置

spring.data.mongodb.host=mongo
