   This problem mentioned above also happen at the sharding-jdbc version 4.x, 5.0.
   It seems that the problem is relation to the springboot version which is responsibility for resoving the configuration name. I soloved the problem with changing the datasource name using '**-**' not the '**_**' .
   
   my exception message bellows:

   and the profile is :
   `
