好，我已经从配置中删除了选项properties.hibernate.temp.use_jdbc_metadata_defaults: false，现在看来可以了.

Ok, I've removed the option properties.hibernate.temp.use_jdbc_metadata_defaults: false from my configuration and now it seems to work.

我不确定为什么要首先添加此选项，我认为有一条警告提示我应该添加此选项...

I'm not sure why I added this option in the first place, I think there was a warning that suggested I should add it...
