【问题描述】：

每当我尝试在 macOS 中进行 mvn build 时，应用程序中都会出现以下错误，我尝试更改网络，重新启动 Postgres 服务器，但没有任何工作。

我的系统 11 和 9.5 中有两个版本的 Postgresql，我使用的是 5432 端口 11 版本

应用程序需要的版本是postgresql 11，但在终端显示9.5（不知道可能是它的客户端版本）

psql (PostgreSQL) 9.5.13

Postgres version :
psql (9.5.13, server 11.0)
WARNING: psql major version 9.5, server major version 11.

    标签： java postgresql macos maven


    【解决方案1】：

    你能显示你的 pom.xml 文件吗 我想你可以忘记 postgres 依赖

            <dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
        </dependency>

    【讨论】：

    • 堆栈跟踪清楚地显示使用了 PostgreSQL 驱动程序。
