Hi community,
Background
---
Now, you must to configure rules when you use ShardingSphere-JDBC, otherwise
it can't be use ShardingSphere-JDBC.
Problem
---
I found that our sql hit feature is already available in the master branch,
this feature can specify dataSource by yourself, such as: /* ShardingSphere
hint: DatasourceName=ds0 */.
Maybe user can use sql hit feature to switch data sources. So we check rules
does it exist. Is it necessary? If it is necessary to check it,
i think the error message cannot tell the user intuitively when user not
configuation rules.
not configuration about rules error message:
```
Unsatisfied dependency expressed through method ‘dataSource’ parameter 0;
nested exception is
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying
bean of type ‘org.apache.shardingsphere.infra.config.mode.ModeConfiguration’
available: expected at least 1 bean which qualifies as autowire candidate.
Dependency annotations: {}.
```
