   ## Question
   I have two database with 4 tables in each.
   db0{tbl0,tbl1,xtbl0,xtbl1}
   db1{tbl2,tbl3,xtbl2,xtbl3}
   
   I have configure application.properties but no datasource configuration. Is this problem means I should manually implement the datasource configuration?
   
   Sorry for no demo code provided since the code should be private.
