我想用后端：Spring Boot，前端：Angular 和 Postgresql DB 创建一个 docker-compose。 我在互联网上尝试了所有方法，但它不起作用。 它正在连接，几秒钟后它说连接被拒绝
我的 Docker-Compose：
version: '3'
services:
database:
image: postgres:13.3
container_name: database
environment:
POSTGRES_DB: "fahrzeuge_verwalten"
POSTGRES_USER: "postgres"
POSTGRES_PASSWORD: "postgres"
ports:
- 5432:5432
networks:
- backendNetwork
springapi:
image: openjdk:11-jre-slim
container_name: springapi
ports:
- 8080:8080
depends_on:
- database
volumes:
- ./target/fahrzeugverwaltung-0.0.1-SNAPSHOT.jar:/app.jar
command: ["java", "-jar", "app.jar"]
networks:
- backendNetwork
- frontendNetwork
angular:
image: nginx:alpine
container_name: angular
ports:
- 4200:80
depends_on:
- springapi
volumes:
- ./nginx.conf:/Users/betu/Documents/Docker-Compose/nginx.conf
- ./carManagement/dist/carManagement/:/usr/share/nginx/html
networks:
- frontendNetwork
volumes:
fahrzeugverwaltungData:
networks:
backendNetwork:
frontendNetwork:
应用程序属性：

spring.datasource.username=postgres
spring.datasource.password=postgres

spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

我是初学者，请问有人能帮我解决这个问题吗？
答案 0 :(得分：0)
在您的应用程序属性文件中
你有
spring.datasource.url= jdbc:postgresql://database:5432/fahrzeuge_verwalten
应该是
spring.datasource.url= jdbc:postgresql://locahost:5432/fahrzeuge_verwalten
或更好
spring.datasource.url= jdbc:postgresql://127.0.0.1:5432/fahrzeuge_verwalten
如果您通过 VPN 连接，请在命令提示符下执行 ipconfig 并使用 VPN IPV4 IP 地址代替 localhost，以防 localhost 无法正常工作。
