   @zjcnb  
   I just saw your reply .
   ```
   k=name
   mode = ModeConfiguration(file,standalone)
   v=(master,slave)
   rules=(new 
ShardingRuleConfigurationYamlSwapper()).swapToObject(YamlReadwriteSplittingRuleConfiguration[from
 yml])
    ShardingSphereDataSource shardingSphereDataSource =
                           (ShardingSphereDataSource) 
ShardingSphereDataSourceFactory.createDataSource(
                                   k, mode, v, rules, shardingProps.getProps());
   ```

   ````
   
   db2-Datasource ：
   Omitted, basically consistent with the above
   
   When progarm restart，here will load all of the datasource of 
metadata(`StandaloneContextManagerBuilder`)
