提取关键信息:

Caused by: javax.net.ssl.SSLHandshakeException: Remote host terminated the handshake
Caused by: java.io.EOFException: SSL peer shut down incorrectly

得知 SSL 握手失败,于是我找了 Azure 的示例代码( https://docs.azure.cn/zh-cn/mysql/connect-java )来测,也是同样的问题。

又参考了《 How to configure spring boot application to use SSL/TLS over MySQL? 》去信任 Azure 的 CA 证书,仍然不起作用。

最后发现是我用的 mysql-connector-java 版本过低导致,我们使用的 Camunda 的 docker 镜像内置了 5.1.21 的数据库驱动,我的测试代码也是同样的版本,连接不上,只要升级到目前的最新版 5.1.49 ,问题就解决了。

另一个坑,如果收到提示

ERROR 9002 (28000): The connection string may not be right. Please visit portal for references.

一般是连接用户名没有加实例名,比如数据库地址是 abc123.mysql.database.chinacloudapi.cn ,那么连接用户名要以 @abc123 结尾。

还有 Azure 整理了一个使用数据库时的常见问题列表,里面有很多问题都会踩到,建议看看——
