和docker-compose.yml作为

version: '3.1'
services:
  app:
    container_name: springboot-postgresql
    image: springboot-postgresql
    build: ./
    ports:
      - "8080:8080"
    depends_on:
      - postgresqldb
  postgresqldb:
    image: postgres
    ports:
      - "5432:5432"
    environment:
      - POSTGRES_PASSWORD=postgres
      - POSTGRES_USER=postgres
      - POSTGRES_DB=employeedb

甚至我也检查了连接5432端口的数据库

但是，我仍然在尝试时出错

码头工人整理

演示如何将postgresdb连接到5432端口（如果可以解决我的错误）

---

我已经检查了postgresql.conf，它显示了5432端口。

从日志中，数据库已经启动并准备就绪

我认为问题在于

.jar

是否可以尝试在项目目录中使用以下命令构建jar：

./mvnw clean package -DskipTests

---

然后再次尝试

docker compose up

。

我尝试了这个，但没有成功，我认为数据库还没有准备好，因为错误日志显示：与postgresqldb的连接：5433被拒绝。检查主机名和端口是否正确，以及邮局主管是否正在接受TCP/IP连接。数据库已在postgres映像日志中启动并准备就绪：

[36mpostgresqldb_1|[0m 2021-05-26T18:27:35.188808600Z 2021-05-26 18:27:35.188 UTC[1]日志：数据库系统已准备好接受连接。

。我尝试了repo，在我的计算机上没有错误。您是否在docker/计算机上运行其他postgres？您使用过windows吗？在运行之前，我已经删除了docker中运行的其他容器/映像。即使如此，它也会给出相同的错误。您是否尝试过

docker rmi springboot postgresql

让docker重新构建映像？如果在删除映像时遇到错误，请尝试

docker rmi-f springboot postgresql

。我认为重新创建映像可以解决您的问题。

./mvnw clean package -DskipTests
