无法连接到Docker容器中运行的MySQL（使用Docker maven插件配置）

我在连接Docker容器中运行的MySQL服务器时遇到问题。这里是一个

docker-maven插件

配置

通过JDBC连接时出错，

maven故障保护插件

连接失败：我尝试连接

localhost:3308

，

127.0.0.1:3308

，

0.0.0:3308

和

10.0.75.0:3308

。另外，尝试了网络类型、

网桥

、

主机

和

容器

Docker网络配置：

---

主要是关于mysql版本

如果您尝试使用mysql:5.7，它可能会起作用

在以后的版本中，安全性要求是不同的

它可以通过以下方式禁用：

默认\u身份验证\u插件=mysql\u本机\u密码

---

但是我不知道把它放在docker maven插件的什么地方。

最后

mysql:5.7

成功了。我没有尝试禁用此

默认\u身份验证\u插件

。问题是，在容器中，MySQL在日志中打印了两次

mysqld:ready for connections

。最后的打印是在

临时服务器停止后进行的

。在此之前的任何连接尝试都将导致失败。更好的选择是检查MySQL init进程是否完成。准备启动。在日志中，因为它只打印一次。
