通过 spring 引导连接到远程数据库 [mysql] 奇怪地无法正常工作
Connect to the remote db [mysql] via spring boot strangely not working
我有一个 spring 启动应用程序，它通常使用本地 mysql 数据库。但是一旦我在自己的 raspberry-pi 服务器上创建了一个 mysql 服务器和 mysql 数据库。所以我创建了一个 PuttY 连接来创建隧道。
我之前所做的 - 所以你不必向我建议该选项：
- 我已经扩展了最大包裹尺寸
- 我已授予我的用户更多权限
- 多次重置服务器
屁股你可以看到我已经连接：
此外，当我想通过 Intelij 连接数据库时，在数据库选项卡中，我还可以：
但是当我尝试通过应用程序连接时 - 通过 运行 应用程序，我遇到了这样的错误：
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
