   Two problems:
   
   1. When `new ShardingAutoTableRuleConfiguration`, the second parameter 
should be `ds`, only specify dataSources:
   ````java
   `ShardingAutoTableRuleConfiguration(final String logicTable, final String 
actualDataSources)`
   ````
   
   2. Regarding inline expressions, no matter what your actual databases are 
called, the keys in dataSourceMap can be regular, such as
   ````java
    Map<String,DataSource> dataSourceMap = new HashMap<>();
   dataSourceMap.put("ds_0",dataSource); // shardingone
   dataSourceMap.put("ds_1",dataSource1); // shardingtwo
   ShardingRuleConfiguration shardingRuleConfiguration = new 
ShardingRuleConfiguration();
   ShardingTableRuleConfiguration nihao = new 
ShardingTableRuleConfiguration("user","ds_${0..1}");
   shardingRuleConfiguration.getTables().add(nihao);
   ````
