   my project use sharding-jdbc,4.1.1 version,and meet a problem!
   
   **Error creating bean with name 'shardingDataSource' defined in class path 
resource 
[org/apache/shardingsphere/shardingjdbc/spring/boot/SpringBootConfiguration.class]:
 Bean instantiation via factory method failed; nested exception is 
org.springframework.beans.BeanInstantiationException: Failed to instantiate 
[javax.sql.DataSource]: Factory method 'shardingDataSource' threw exception; 
nested exception is java.sql.SQLException: Can't find file: 'data_10' (errno: 2 
- No such file or directory)**
   
   I debuged and found that sharding jdbc perform both 
loadShardingSchemeMetaData and loadDefaultSchemeMetaData in the 
ShardingMetaDataLoader class.
   
   I don't know why loadDefaultSchemeMetaData method need be invoked, and it 
seems there is no parameter can prevent it。
   this property check.table.metadata.enabled set false as default and it just 
work on loadShardingSchemeMetaData method,
   What is the actual meaning of this parameter?
   Did anyone meet the same problem,please give me some help!
   Thx!
