spring boot 无法使用 Intellij 连接到 MYSQL 数据库

Question

请帮帮我，我花了 2 天时间解决这个小问题，但我还不知道如何解决。

我已经在本地 Windows 10 PC 的 docker 容器中安装了 mysql。

mysql 服务器工作正常（从 MySQL Workbench 运行）

但是当我尝试从 intellij 运行时，会出现这些错误消息。

Answer 1

当 Docker 运行 MySQL 时，您必须使用 127.0.0.1 而不是 localhost。这是因为当 MySQL 客户端尝试连接到 localhost 时，它会查找套接字文件描述符而不是使用 TCP/IP。

在这篇文章中有解释：Connect to Docker MySQL container from localhost?

Answer 2

当我检查我的任务管理器时，我发现另一个 mysql 进程正在工作

关闭后问题解决

谢谢你
