[GitHub] [shardingsphere] zhang-j-x opened a new issue #9066: A question about datasource names
zhang-j-x opened a new issue #9066:
URL: https://github.com/apache/shardingsphere/issues/9066
when i try to config the demo of sharding databases tables,at first,i config like this
and then i found it run error
i realized the config of datasource.names must be as same as the name of physical database,but i found it strange that why not use the name of physical database as the key of datasourceMap,the configuration property name can not appear '-',when i used the database name like sharding_sphere,it will run error.

About the second point ,it's not what i want,but ShardingSphere needs to configure the datasource.names with the actual database names.I just want to configure like this

Hi ~ @zhang-j-x ! Thanks for your feedback!
In fact, datasource.names is a logical database name, which can be inconsistent with the actual database name.
Do you also report an error in the url when you use "_"?

Hi @zhang-j-x ,
You use Sharding-JDBC Datasource with SpringBoot, don't you?
Let me iterate your case. Please correct me if something is misunderstood,
- The databases in your MySQL instance are named with `-`
- You want to configure the `datasource.names` with the actual database names
- But there is an exception
Actually, ShardingSphere has no such limitation. Could you give SpringBoot Configuration a check? I remember some version of `SpringBoot` has terrible support for keys with `-`.

yes，rename can solve this problem，but it means that it not supports the database which name contains '_', sometimes we can not rename the physical database's name.The version i use is 5.0.0-alpha.

How about rename `sharding_sphere` without `_` ? BTW, which version is in your case?
