我将分享我的 Dockerfile

注意
当我构建jar文件并单独运行它时，它可以工作，所以我开始认为问题来自dockerfile但我不知道，请帮助。
【问题讨论】：
在 docker 中部署时，您的 postgres 未在 localhost 上运行，除非您更新 Postgres 容器以包含您的 jar，我对此表示怀疑。 URL 应该指向包含 Postgres 的 docker 容器的名称。 我不认为这是问题所在，我在本地机器上公开了端口，以便在点击 localhost:5432 时可以找到它，证明我正在连接到数据库使用带有 localhost url 的 DataGrip 这是来自你的本地机器而不是来自容器内。 我将此添加到 Spring Boot 环境环境中：-'spring.datasource.url=jdbc:postgresql://postgres:5432/appointmentSystem' 仍然出现此错误“由：org.postgresql .util.PSQLException：连接到 localhost:5432 被拒绝。”环境不应该覆盖application.yml吗？ 您应该使用SPRING_DATASOURCE_URL 作为环境名称，spring.datasource.url 不允许作为名称（AFAIK . 不允许在名称中使用）。
【参考方案1】：
您的应用程序正在尝试连接到localhost:5432。相反，您应该通过 postgres:5432 连接到 postgress 服务
【讨论】：
我不认为这是问题所在，我在本地机器上公开了端口，以便在点击 localhost:5432 时可以找到它，证明我正在连接到数据库使用带有 localhost url 的 DataGrip 您的应用程序位于容器内。您本地计算机的localhost 接口与应用程序容器内的localhost 接口不同。
我将此添加到 Spring Boot 环境环境中：-'spring.datasource.url=jdbc:postgresql://postgres:5432/appointmentSystem'，但我仍然收到此错误“原因：org.postgresql .util.PSQLException：连接到 localhost:5432 被拒绝。”环境不应该覆盖application.yml吗？以上是关于docker-compose spring boot无法连接到Postgres [重复]的主要内容，如果未能解决你的问题，请参考以下文章
